Why Choose the Unitronics IO-DI16 Digital Input Expansion Module?
The Unitronics IO-DI16 is a reliable digital input expansion module designed for use with Unitronics Vision PLC controllers. It allows engineers to expand PLC systems by adding additional digital inputs for monitoring switches, sensors and other discrete field devices within industrial automation environments.
The module provides 16 digital inputs arranged in two groups, supporting both PNP (source) and NPN (sink) wiring configurations. This flexible design allows integration with a wide range of industrial sensors and control devices commonly used in factory automation and machine control systems.
One of the inputs can operate as a high-speed counter input, enabling accurate measurement of pulse signals, encoder feedback or frequency signals. The module connects to the PLC via an expansion adapter and can be mounted directly onto a 35 mm DIN rail or fixed to a panel inside a control cabinet.
