Digital Voltage Comparator 0-100V Voltage Measurement Control Voltage Measuring Charge Discharge Protection Overvoltage Undervoltage Overload Protection (12V)

Parameters:

Module work voltage: DC 12V (nominal voltage should not exceed +/- 10%).

Current: less than 12V, 50mA (relay action not less than 12mA, turn off the display less than 3mA).

Operating temperature: Recommended -20 -60 (the limits of -30 -70 ).

Measuring range: 0-99.9V.

load capacity:

Normally open relay port maximum load capacity: DC 0-30V / 10A, AC 0-250V / 10A;

Relay NC port maximum load capacity: DC 0-28V / 10A, AC 0-125V / 10A.

Module interface:

Module voltage inputs: a 4-wire interface, all the terminals are the interface, user-friendly;

1, DC +: DC power positive;

2, DC-: DC power supply negative;

3, V +: measuring voltage positive electrode;

4, V-: measure negative voltage.

Function Module:

The user can select from the following five kinds of functions in one, you can set and save function parameters are automatically saved parameter set, power-down is not lost.

Function1: Voltage measurement: this function is selected, the relay will not operate, digital display of the current measurement voltage.

Function 2: Charge monitoring: When the measured voltage falls below a preset voltage V1 and V2 in the lower one, relay, voltage V1 and V2 higher than the higher of a relay off.

Function3: Discharge Monitoring: When the measured voltage is higher than the preset voltage V1 and V2 higher one, relay, T1 and T2 voltage is lower than the lower one, the relay off.

Function 4: pull the interval: When measuring the voltage between V1 and V2 between, relay, the relay off other cases.

Function 5: interval outer pull: When the measured voltage falls below a preset voltage V1 and V2 in a lower or higher than the preset measuring a voltage higher voltages V1 and V2, the relay is energized; otherwise relay disconnect.
