UID-W1616R Unistream Input/Output Expansion Module with 16 Digital Inputs and 16 Relay Outputs

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

The Unitronics UID-W1616R is a powerful UniStream Uni-I/O Wide expansion module designed to significantly increase the input and output capacity of Unitronics UniStream PLC systems. The module provides 16 digital inputs and 16 relay outputs, allowing industrial controllers to monitor field signals and switch loads from a single high-density module.

Part of the UniStream Uni-I/O Wide series, this module is wider than standard Uni-I/O modules, enabling more I/O points in a compact footprint. It can be installed directly on the back of a UniStream HMI panel with a CPU-for-Panel or mounted on a DIN rail using a local expansion kit.

The relay outputs support switching of both AC and DC loads, making the module suitable for controlling contactors, valves, motors and signalling devices. Its flexible digital inputs support both sink and source wiring for compatibility with a wide range of industrial sensors and switches.
