GENERAL DESCRIPTION
The Trentech 237 Master and 238 Slave Relay Boards are compact panel mounted circuit boards designed to interface directly with high-density output modules from several manufacturers of industrial grade programmable logic controllers. Convenient “sems” type screw terminals are provided for field terminations and “pluggable” connectors are provided for P.L.C. or control panel interface.
Reliable high current mechanical relays are provided for control of A.C. or D.C. circuits, dry contacts, or a mixture of all types simultaneously. Each circuit is fuse protected and easily identified with the provided “clip-on” terminal strip covers. “Bussable” neutral and relay common points are available on terminal strips and are configurable via zero ohm resistors, insulated wire jumpers, or bus strips depending on user requirements.
