Conrad Business Supplies has added the latest Weidmüller u-remote HD high-density remote I/O modules to its industrial automation portfolio. They are used for connecting sensors and actuators to a PLC or central controller. u-remote I/O modules measure 11.5mm. Within this form factor, the latest HD modules accept eight plug-in connectors, each with connections for four wires, to allow up to 32 connections on a single module. This enables designers to use fewer modules and achieve smaller cabinet sizes. The four-wire HD plugs allow many types of sensors or actuators to be connected, and accept wire sizes from 0.14mm² to 0.32mm².
