CONPROSYS Robust I/O Series - Industrial remote I/O modules

IEC 61000 Certified

ESD/EFT/Surge Protection

Extreme Environments Destroy Standard I/O Equipment

Standard remote I/O modules fail catastrophically in harsh industrial conditions—causing unplanned downtime, data loss, and equipment replacement costs that devastate operational budgets.

Temperature-Induced Failures

Standard I/O modules operate only within narrow temperature ranges (0 to 50°C), failing immediately in foundries, outdoor installations, and thermal process environments.

IMPACT:

Unplanned shutdowns, recalibration delays, emergency replacements

Electrical Noise Corruption

Electrical interference from VFDs, welding equipment, and high-power machinery corrupts data acquisition, producing measurement errors and false triggers.

IMPACT:

Inaccurate process control, quality defects, regulatory non-compliance

Voltage Spike Destruction

High-voltage transients from motor startups, lightning strikes, and power surges permanently damage unprotected input/output circuits.

IMPACT:

Module replacement costs, extended downtime, lost production

Wiring Error Vulnerabilities

Miswiring during installation or maintenance destroys input circuits without overvoltage protection, requiring complete module replacement.

IMPACT:

Hardware damage, troubleshooting delays, technician retraining

Communication Blackouts

Network failures and module malfunctions occur silently without watchdog monitoring, causing invisible data loss and undetected system failures.

IMPACT:

Silent failures, delayed fault detection, cascading system errors

Unsafe Output Behavior

When host communication fails, outputs remain in unpredictable states, potentially damaging connected actuators or creating hazardous conditions.

IMPACT:

Safety risks, equipment damage, liability exposure

High Costs

Frequent module replacements and emergency repairs

Extended Downtime

Unplanned shutdowns and troubleshooting delays

Data Loss

Corrupted measurements and missed critical events

26 Models

Ethernet + RS-485

IEC 61000 Certified

ESD/EFT/Surge Protection

Extreme Environments Destroy Standard I/O Equipment

Standard remote I/O modules fail catastrophically in harsh industrial conditions—causing unplanned downtime, data loss, and equipment replacement costs that devastate operational budgets.

Temperature-Induced Failures

Standard I/O modules operate only within narrow temperature ranges (0 to 50°C), failing immediately in foundries, outdoor installations, and thermal process environments.

IMPACT:

Unplanned shutdowns, recalibration delays, emergency replacements

Electrical Noise Corruption

Electrical interference from VFDs, welding equipment, and high-power machinery corrupts data acquisition, producing measurement errors and false triggers.

IMPACT:

Inaccurate process control, quality defects, regulatory non-compliance

Voltage Spike Destruction

High-voltage transients from motor startups, lightning strikes, and power surges permanently damage unprotected input/output circuits.

IMPACT:

Module replacement costs, extended downtime, lost production

Wiring Error Vulnerabilities

Miswiring during installation or maintenance destroys input circuits without overvoltage protection, requiring complete module replacement.

IMPACT:

Hardware damage, troubleshooting delays, technician retraining

Communication Blackouts

Network failures and module malfunctions occur silently without watchdog monitoring, causing invisible data loss and undetected system failures.

IMPACT:

Silent failures, delayed fault detection, cascading system errors

Unsafe Output Behavior

When host communication fails, outputs remain in unpredictable states, potentially damaging connected actuators or creating hazardous conditions.

IMPACT:

Safety risks, equipment damage, liability exposure

High Costs

Frequent module replacements and emergency repairs

Extended Downtime

Unplanned shutdowns and troubleshooting delays

Data Loss

Corrupted measurements and missed critical events

DIN Rail Mounting (35mm Standard)

All CONPROSYS Robust I/O modules are designed for standard 35mm DIN rail mounting, allowing quick installation in control panels, junction boxes, and industrial enclosures.

Mounting Procedure:

①Hook the top of the module onto the DIN rail
②Press the bottom of the module firmly until it clicks into place
③Verify secure mounting by gently pulling the module
④Leave adequate spacing between modules for heat dissipation and cable routing

CPSR-ET7200

120 × 76 × 38 mm

CPSR-M7000

122 × 72 × 34 mm

Power Supply Connection

CONPROSYS Robust I/O modules operate on 10-30VDC power supply with reverse polarity protection and wide input voltage tolerance for industrial power conditions.

Power Wiring Guidelines:

•Power Range: 10-30VDC (typical 24VDC industrial supply)
•Wire Gauge: Use AWG 16-24 (0.25-1.5mm²) for power connections
•Polarity: Observe correct polarity (+Vs and GND terminals)
•Grounding: Connect FG (Frame Ground) terminal to protective earth
•Protection: Use external circuit breaker or fuse (recommended 1-2A)

Important Safety Notice

Verify power supply voltage before connection. Excessive voltage may damage the module. Disconnect power when wiring I/O terminals to prevent electrical shock or equipment damage.

Communication Network Setup

Ethernet TypeET7000/ET7200 Modbus-TCP

Ethernet models use standard RJ-45 connectors with 10/100BASE-TX communication supporting daisy-chain or star topology configurations.

Ethernet Wiring Options:

Option 1: Star Topology (Network Switch)

• Connect each module directly to Ethernet switch using Cat5e/Cat6 cable
• Maximum cable length: 100 meters per segment
• Suitable for large installations with centralized switch

Option 2: Daisy-Chain (ET7200 with LAN Bypass)

• Use two RJ-45 ports on ET7200 for daisy-chain connection
• Reduces cabling complexity in linear installations
• LAN Bypass maintains network when module is powered off

Network Configuration

• Set unique IP address for each module
• Configure subnet mask (typical: 255.255.255.0)
• Set gateway address if required
• Default Modbus port: 502

Cable Specifications

• Use Cat5e or Cat6 Ethernet cable
• Shielded cable recommended for noisy environments
• Maximum nodes: 247 modules per network
• Speed: 10/100 Mbps auto-negotiation

RS-485 TypeM7000 Modbus-RTU

RS-485 models support long-distance multi-drop communication up to 1.2 kilometers using twisted-pair cabling with termination resistors.

RS-485 Wiring Requirements:

①Cable Type: Use twisted-pair cable (shielded recommended)
②Wire Gauge: AWG 20-24 (0.5-0.8mm²) suitable for up to 1.2km
③Topology: Multi-drop bus (all modules in parallel on D+ and D- lines)
④Termination: Install 120Ω termination resistor at both bus ends
⑤Node Address: Set unique Modbus address (1-247) for each module
⑥Baud Rate: Configure matching baud rate on all modules (9600, 19200, 38400, 57600, 115200 bps)

Communication Parameters

• Protocol: Modbus-RTU
• Max distance: 1.2 kilometers

Termination Resistor

• Value: 120Ω (1/4W or higher)
• Location: First and last module on bus
• Connection: Between D+ and D- terminals
• Purpose: Prevent signal reflection

I/O Terminal Connections

Connect field sensors, actuators, and control signals to I/O terminals with proper wiring and grounding practices for reliable operation in harsh environments.

Analog Input Wiring

• Use shielded twisted-pair cable for long runs
• Connect shield to FG at module end only
• Observe polarity for voltage/current inputs
• Configure input range via software utility
• Verify disconnection detection for 4-20mA loops

Sensor Input Wiring (RTD/TC)

• RTD: Use 3-wire or 4-wire configuration
• Thermocouple: Observe correct polarity (+/-)
• Use compensating cable for thermocouples
• Enable open wire detection in software
• Configure sensor type (Pt100, K-type, etc.)

Digital Input Wiring

• Select Sink or Source input mode via DIP switch
• Use screened cable in high-noise environments
• Dry contact: Voltage-free switch closure
• Wet contact: External voltage source (3.5-80VDC)
• Maximum input voltage: ±70VDC (protection)

Output Wiring (Relay/Digital)

• Power relay: Up to 16A @250VAC/30VDC
• PhotoMOS relay: 60-80V @1.0A (temp derating)
• Digital output: Open collector sink/source
• Use external snubber circuit for inductive loads
• Configure safe mode for communication loss

High Voltage Warning

Power relay outputs switch high voltage (up to 250VAC). Only qualified personnel should perform wiring. Disconnect power before wiring. Follow local electrical codes and safety regulations.
