£150.50
The Unitronics URD-3200-4 is a high-density remote digital input expansion module designed for the Unitronics UniStream Remote I/O platform. Developed for industrial automation, machine control and distributed I/O applications, this compact module provides thirty-two universal digital inputs, enabling efficient signal acquisition while minimising control cabinet space requirements.
As part of the UniStream Remote I/O family, the URD-3200-4 integrates seamlessly with UniStream Ethernet and EtherCAT remote I/O adapters, allowing machine builders and automation engineers to create scalable and decentralised control systems. Its slim DIN rail footprint makes it particularly suitable for installations where panel space is limited but high input density is required.
Featuring 32 universal digital inputs supporting both sink and source operation, the URD-3200-4 provides flexible connectivity for sensors, switches, push buttons and other industrial field devices. Fast response times and robust industrial construction ensure reliable operation in demanding manufacturing and process automation environments.
Digital input modules such as the Unitronics URD-3200-4 allow automation systems to efficiently monitor large numbers of field devices while reducing wiring complexity. By distributing I/O closer to machinery and process equipment, installation costs can be reduced and system flexibility improved.
The URD-3200-4 is particularly well suited to manufacturing systems, packaging machinery, material handling equipment, production lines and industrial process applications where large numbers of digital signals must be monitored reliably and efficiently.
