Why Choose the Unitronics UID-W1616R Wide Digital I/O Expansion Module?

The Unitronics UID-W1616R is a high-capacity digital input and relay output expansion module designed for the Unitronics UniStream PLC platform. As part of the advanced Uni-I/O Wide Series, this module provides an impressive combination of 16 digital inputs and 16 relay outputs within a single compact unit, helping engineers maximise I/O density while reducing panel space requirements.

Developed for industrial automation, machine control and OEM applications, the UID-W1616R integrates seamlessly with UniStream Built-in, Modular and Virtual PLC systems. Its wide-module design offers significantly more I/O points than standard modules, allowing control systems to expand efficiently while maintaining a streamlined architecture.

Featuring 16 sink/source compatible digital inputs and 16 SPST-NO relay outputs, the UID-W1616R delivers flexible monitoring and control capabilities for industrial machinery, process systems, conveyors and manufacturing equipment. All inputs and outputs are electrically isolated to improve system reliability and protection in demanding industrial environments.

Key Advantages

  • 16 digital inputs and 16 relay outputs in a single module.
  • Part of the Uni-I/O Wide Series for higher I/O density.
  • Compatible with the complete Unitronics UniStream platform.
  • Supports both PNP and NPN input wiring.
  • Relay outputs suitable for AC and DC loads.
  • All inputs and outputs electrically isolated.
  • Reduces control panel space requirements.
  • Simple integration using UniLogic software.

Key Features

  • Unitronics Uni-I/O Wide Series.
  • 16 digital inputs.
  • 16 relay outputs.
  • Sink (PNP) and Source (NPN) compatible inputs.
  • SPST-NO (Form A) relay output contacts.
  • Two isolated groups of 8 inputs.
  • Four isolated groups of relay outputs.
  • 24 VDC control operation.
  • Status LEDs for diagnostics and monitoring.
  • DIN rail or local expansion installation capability.

High-Density Digital Monitoring and Control

The UID-W1616R is designed for applications requiring large numbers of digital inputs and outputs while minimising hardware footprint. Its wide-module architecture enables engineers to add thirty-two I/O points using a single expansion module, reducing wiring complexity and simplifying control panel layouts.

The relay outputs provide excellent flexibility for switching both AC and DC loads, making the module suitable for controlling contactors, valves, indicators, alarms and other industrial equipment. Combined with sixteen digital inputs, the module offers a powerful solution for machine monitoring and process control applications.
