IN+ : Forced switch signal input
IN- : Forced switch signal input
NO : The relay is normally open
COM: relay common terminal
NC : Normally closed terminal of relay

Instructions for use:

After the module is powered on, the indicator light flashes four times and then stays on, the digital tube displays the testing voltage, short press the SET key to enter the setting, the set value digit flashes, press the ENTER key to make the set value from 0 to 9 The cycle increases, the first to be set is the upper limit of the voltage, short press the SET button three times, the second group to be set is the lower limit of the voltage, the lower limit of the voltage cannot be set higher than the upper limit, (if the lower limit is The value cannot be set, please increase the upper limit first), short press the SET key to enter the third group of values for the voltage correction value, the default is 0, the setting range is -0.5 ~ +0.5, and the fourth group of values is the digital tube The time of automatic shutdown, such as ''dL0'' means that the digital tube is always on, ''dL9'' means that the digital tube is automatically turned off after 9 minutes. After pressing the SET setting, the digital tube is no longer flashing. At this time, it enters the voltage testing control mode and collects real-time data. Display the DC voltage value input from the outside, when the detected voltage is higher than the set voltage upper limit, the relay will pull in (normally open point is connected, normally closed point is disconnected), until the voltage is lower than the set voltage lower limit value , the relay is released (the normally closed point is connected, and the normally open point is disconnected).

When the voltage is detected, press and hold the SET button for three seconds and then release it, the logicc state of the voltage control relay will be reversed. You can use this operation to achieve the voltage higher than the upper limit relay pull-in, or the voltage lower than the lower limit relay pull-in.

When the voltage is detected, short press the ENTER key to switch the minute timing time of the relay's pull-in status (the rightmost decimal point flashes when the timing is in progress). When the relay is released, the timing stops. Press and hold ENTER for three seconds to reset the timer value.

The forced switch can be externally connected or a voltage signal (DC5-26V) can be used to force the relay to pull in. When the external switch or voltage signal is continuously input, the relay pulls in. When the switch or signal disappears, the relay is controlled by voltage testing.

Note: The testing voltage terminals should be in reliable contact, loose wiring, and lack of insulation around the circuit board may result in inaccurate voltage testing values.
