Connection:
- DC+ / DC- : Power supply (12V DC)
- V+ / V- : Voltage to be measured (0...99V DC)
- NO / COM / NC : Relay contact outputs

Delay setting: 0...99.9s

Operating functions (Modes): The module has 5 different modes to choose from, as well as adjustable lower (V1) and upper (V2) voltage limits:

-F1 - Voltage measurement: The relay does not switch, the module only displays the current measured voltage.

-F2 - Charging supervision (Hysteresis): If the measured voltage falls below the lower limit, the relay is activated. If it reaches the upper limit, the relay is released.

-F3 - Discharge supervision (Hysteresis): If the measured voltage goes above the upper limit, the relay is activated. If it falls below the lower limit, the relay is released.

-F4 - Window Comparator (In Range): The relay energizes when the voltage is between the set lower and upper limits.

-F5 - Inverted Window Comparator (Out of Range): The relay energizes when the voltage is less than the lower limit OR greater than the upper limit.
