Plug-in power protective circuit solid-state relay, with signal logic, can be plugged into 4-pos. basic terminal
blocks, input: 24 V DC, output: short-circuit-proof, 18 - 36 V DC/1 A
Product Features
Reliable detection and indication of an open circuit on the load side
Time-dependent overload shutdown for reliable protection against continuous overloads
Fast short circuit shutdown with simultaneous current limitation
Feedback in the event of an error
Brief inrush peaks are ignored
After an overload or short-circuit has been triggered, a defined reset of the control voltage must be carried out
