URD-0032NG-4 – Unitronics DO32,Sink,24VDC/0.3A,40P

Why Choose the Unitronics URD-0032NG-4 Digital Output Module?

The Unitronics URD-0032NG-4 is a high-density 32-channel NPN digital output module designed for the UniStream Remote I/O platform. It provides 32 sink-type transistor outputs operating at 24 V DC, enabling PLC systems to control relays, actuators, solenoids and signalling devices across distributed industrial automation systems.

Installed within a UniStream remote I/O assembly, the module connects to a remote Ethernet I/O adapter which communicates with the PLC controller. This distributed architecture allows engineers to place I/O modules close to machinery and field equipment, reducing wiring complexity while enabling scalable automation systems.

With 32 high-density transistor outputs, fast switching response and a slim DIN-rail form factor, the URD-0032NG-4 provides reliable digital output expansion for modern industrial automation and machine control environments.
