Do you have a question about the Unitronics V200-18-E3XB and is the answer not in the manual?

The V200-18-E3XB is a snap-in I/O module designed to integrate directly into compatible Unitronics OPLCs, forming a self-contained PLC unit with local I/O capabilities.

Function Description:

This module provides a comprehensive set of I/O features for industrial automation applications. It includes 18 isolated digital inputs, 15 isolated relay outputs, 2 isolated transistor outputs, 4 isolated analog/PT100/TC inputs, and 4 isolated analog outputs. The digital inputs support both pnp (source) and npn (sink) types, with two inputs capable of high-speed counter (HSC) functionality. The relay outputs are SPST-NO (Form A) and are isolated by relay. The transistor outputs are high-speed and can be individually configured as pnp (source) or npn (sink) via wiring and jumper settings. The analog inputs are highly versatile, supporting current, voltage, RTD (PT100), and thermocouple (B, E, J, K, N, R, S, T types) measurements, configurable via wiring and jumper settings. The analog outputs provide 0-10V or 4-20mA signals.

Usage Features:

Wiring: Use crimp terminals for wiring with 26-12 AWG wire. Ensure proper stripping (7±0.5mm), insertion, and tightening of wires. Avoid exceeding 0.5 N·m torque to prevent wire damage. Do not use tin, solder, or other substances on stripped wire. Install wiring at maximum distance from high-voltage cables and power equipment. Input/output cables should not share multi-core cables or the same wire.
Digital Inputs: Each group of 9 inputs shares a common signal and can be configured as pnp (source) or npn (sink). Inputs 10 and 12 can be used as normal digital inputs, high-speed counters, or part of a shaft encoder. Inputs 11 and 13 can be used as normal digital inputs, high-speed counter resets, or part of a shaft encoder.
Digital Outputs: Use a 24VDC power supply. Each relay output can be wired separately to either AC or DC loads. The 0V signal of relay outputs is isolated from the controller's 0V signal. Transistor outputs can be configured as npn or pnp via jumper settings and wiring. The 0V signal of transistor outputs is isolated from the controller's 0V signal.
Analog I/O Power Supplies: A 24VDC power supply is required for all analog input and output modes. The analog I/O power supply is isolated, allowing the controller's 24VDC power supply to be used. The 24VDC power supply must be turned on and off simultaneously with the controller's power supply.
Analog Inputs: Inputs can be wired for current or voltage. When set to current/voltage, all inputs share a common ACM signal. RTD inputs require one lead wired to the common signal (CM). 4-wire PT100 can be used by leaving one sensor lead unconnected. Thermocouple inputs support various types (B, E, J, K, N, R, S, T) and can be set to mV by software.
Analog Outputs: Outputs can be wired for either current or voltage.
Jumper Settings: Jumper settings for analog inputs and digital/analog outputs are critical for configuring the module's functionality. These settings are accessed by removing the module from the controller and then removing the PCB board.

Maintenance Features:

Safety Guidelines: Always read and understand the document before use. Only qualified service personnel should open the device. Failure to comply with safety guidelines can result in severe personal injury or property damage.
Equipment Protection: Check the user program before running. Do not use the device with parameters exceeding permissible levels. Install an external circuit breaker and take appropriate safety measures against short-circuiting. Do not connect/disconnect the device when power is on. Ascertain that terminal blocks are properly secured.
Environmental Considerations: Avoid installation in areas with excessive or conductive dust, corrosive or flammable gas, moisture, rain, excessive heat, regular impact shocks, or excessive vibration. Provide proper ventilation by leaving at least 10mm of space around the device. Do not place in water or allow water to leak onto the unit. Prevent debris from falling inside the unit during installation.
Increasing Contact Life Span (Relay Outputs): For inductive DC loads, connect a clamping diode in parallel. For inductive AC loads, connect an RC snubber circuit in parallel.
Warm-up Period: For analog inputs and outputs, a warm-up period of half an hour is recommended to ensure proper performance.
Shielding: Shields for analog inputs should be connected at the signal source. Shields for analog outputs should be earthed, connected to the earth of the cabinet.
Troubleshooting (Analog Inputs): The analog value can indicate faults such as input value deviating above/below the input range or power supply disconnection.
Troubleshooting (PT100 Inputs): The analog value can indicate faults such as sensor not connected, value exceeding permissible range, power supply disconnected, or sensor short-circuited.
Troubleshooting (Thermocouple Inputs): The analog value can indicate faults such as sensor not connected, value exceeding maximum/minimum, or power supply disconnected.
Accessing Jumpers: To access jumpers, turn off power, disconnect and dismount the controller. Discharge any electrostatic charge by touching a grounded object. Avoid touching the PCB board directly; hold it by its connectors. Remove the snap-in module by pressing the 4 side buttons and gently rocking it. Remove the center screw from the upper PCB board and lift the PCB board by its edges.
Reassembly: Return the PCB board, secure the center screw. Reinstall the module by aligning circular guidelines and applying even pressure until a 'click' is heard. Ensure all sides and corners are correctly aligned.
