User ManualThe Current Monitoring Relay monitors AC/DC current signals and mV signals for MIN and MAX Alarm and transmits the limit value message to the switching output.
The configuration is carried out via DIP switches or via the front programming interface (requires DZU 1201, see accessories). The monitoring relay has an adjustable switch-on delay, switch-off delay and a wiper function. Further settings such as latch function and window function are also possible.
Power can be supplied via the connection terminals or via the optional In-Rail-Connector (see accessories). The switching status and the device status are indicated by LEDs on the front panel. If the device is operated via the In-Rail Connector, a group message is available.
