1>.Settable reference voltage
2>.Inputs can be selected one or two
3>.Three function options
4>.Relay control output
3.Parametes:
1>.Working voltage: DC 12V
2>.Work current:10mA
3>.Standby current:5uA
4>.Operating Temperature:-20℃~85℃
5>.Operating Humidity:5%~95%RH
6>.Module Size:63*38*19mm
4.Functions:
1>.Function_1: Compare the Input Voltage and the Reference Voltage.The Reference Voltage can be set by potentiometer.Relay output will turn ON if the Input Voltage is more than the Reference Voltage.Relay output will turn OFF if the Input Voltage is less than the Reference Voltage.
2>.Function_2: Compare the Input Voltage A and the Input Voltage B.Relay output will turn ON if the Input Voltage A is more than the Input Voltage B.Relay output will turn OFF if the Input Voltage A is less than the Input Voltage B.
3>.Function_3: Compare the Input Voltage and the Reference Voltage.Its function is site to function_1.This function needs remove jump cap from module and short pads on the back of the PCB.The Reference Voltage can be set by potentiometer.Relay output will turn ON if the Input Voltage is less than the Reference Voltage.Relay output will turn OFF if the Input Voltage is more than the Reference Voltage.
4>.Adjust the Reference Voltage: It comes from module's work voltage.Its adjust range is 0~12V.
