UID-W1616T Unistream Input/Output Expansion Module with 16 Digital Inputs and 16 Transistor Outputs

Why Choose the Unitronics UID-W1616T UniStream Wide Digital I/O Module?

The Unitronics UID-W1616T is a high-capacity UniStream Uni-I/O Wide digital input and transistor output module designed to significantly expand the I/O capabilities of Unitronics UniStream PLC systems. The module combines 16 digital inputs and 16 PNP transistor outputs, allowing industrial controllers to monitor multiple field signals while delivering fast switching control for DC loads.

Part of the UniStream Uni-I/O Wide series, this module is approximately 1.5— wider than standard Uni-I/O modules, enabling a greater number of I/O points within a single expansion unit. It integrates seamlessly with UniStream controllers and can be attached directly to a UniStream HMI panel with a CPU-for-Panel or installed on a DIN rail using a local expansion adapter.

The transistor outputs provide fast response times and are suitable for driving relays, solenoids, indicators and other DC devices in industrial automation systems. With high-density I/O and flexible installation options, the UID-W1616T is ideal for machine builders and system integrators who require scalable PLC control architectures.
