System
Experiment panel system with all necessary digital inputs and outputs as well as the required interfaces. The inputs are accessible via 4 mm safety sockets for 230 V and via the built-in switches with latching and push-button function. The outputs are designed as potential-free relay contacts and are accessible via safety sockets on the front. It is possible to permanently set the sockets to 230 V using jumper plugs. The control unit has an Ethernet interface designed as an RJ 45. The control voltage is 230 V AC.
