Libratherm offers four and eight channel Relay Cards. These cards are mainly designed for interfacing low level switching signal outputs coming from PLC, SCADA, DCS etc.. to the external AC/DC operated switching devices (like contactors, solenoid valves, lamps, motors etc..in industrial automation control application).Various types of such cards are available viz. Single changeover contact card, (1 C/O) two changeover contact card (2 c/o) operating on 12 or 24 VDC supply.
Libratherm also offers AC and DC solid state relay cards (using Triacs and Bipolar Transistors) for 4 or 8 channel controls. AC solid state relay card accepts DC controls signal of (0-5) or (0-10) VDC and can switch any single phase AC load rated at 5A @ 230VAC . DC solid state relay cards also accept (0-5) or (0-10) VDC control signal and can switch the DC load of 5A @ 24VDC (max). The solid state relay cards are useful for fast switching (less than 1 second time) of AC or DC loads. The LED indication for each input control signal is also provided. Each output is All the relay cards can be mounted on the plane surface or can be mounted on universal DIN size rails.
