19 inch panel mounting sockets

Module 19-inch 2U D-relay



The 19” module is equipped with 8 pieces of the V33 relay socket. Each contact on the V33 socket has two high-quality spring terminals, suitable for two wires up to 2.5mm2 (solid or stranded), the looping/daisy chaining can be done on the socket and no external connector or terminal is needed. The spring terminal makes the quick connection possible by pressing the spring with a flat-bladed screwdriver and inserting the stripped wire. Solid and (fine) stranded wire up to 2.5mm2 can be inserted. This quick & easy wiring method saves up to 75% wiring time compared with classic technology, like screw terminals.


For heavy duty, industrial applications, space saving design. Installation and replacement of plug-in relays are made easy and cost saving. No maintenance is required for the user.
