Description, device design, dimension drawing
Using the selectivity module, a 24 V DC output voltage from a regulated power supply can
be distributed across four load circuits. The response threshold of the output current can be
individually set for each output using a potentiometer. When the set response threshold is
exceeded, the output is automatically switched off according to a defined switch off
characteristic, and can be switched on again after a wait time using a pushbutton or remote
reset (SITOP PSE200U). The status of the output is displayed using a multi-color LED for
each output. The status of the outputs can be processed via a group signaling contact or via
a serial single-channel signal.
