be selected as the measured variable. 

Additionally, both frequency and phase angle are displayed. Features: 

A relay with changeover contact reacts to configured measurement range limits (on/off switching delay and threshold value switch function can be configured with up to two threshold values). 

Adjustable software filter 

Simulation of input/output response via WAGO Interface Configuration Display 

Analog unipolar/bipolar signals (current/voltage) at output 

Additional digital signal output for configured measurement range limits 

The digital output can be configured as a frequency generator or pulse output (S0 interface). 

## Notice: 

The device is supplied with 24 VDC, which can be commoned using lateral push-in type jumper bars: (6.1) US+ (BR) and (6.2) GND 2 (BR). With this variant, it is necessary to ensure that the max. permissible total current of 6 A is not exceeded.
