- Applicable to a wide power supply range (100 to 240V AC)
- For relay contacts, operation (high/low), hysteresis or fail-safe function are programmable
- Non-volatile memory retains settings in the event of power failure
- Volume indication as well as level indication
- Bar graph and 7 segment 4 digit display for level/volume indication
- Simulation (4 to 20mA DC) available for loop check
- Power, input and output are isolated.
