Mono or multi-channel reset device

By EurolElektrikApplications for building and civil engineering

Application

Object : Specific programmable controller for the control of self-reset of circuit breakers and switches. In the case this PLC controls a circuit-breaker self-reset, as soon as the voltage is out, the PLC will generate a remote reset signal taking into account the context and/or the programmed delay time.

Presentation : Plastic box mounted on DIN track and equipped with :

* inside : an electronic card connected on local voltage supply,
* on front face : a user interface with 8 keys and 5 displays of 7 segments,
* on the sides : screw terminals for the connection to local voltage supply, remote control signals, alarms, serial and output connections of reset control (or connection with the 4 channel extension box for the multi-channel optional device).
