one 1 channel relay module DC 12V high and low level trigger relay control with optocoupler
Description:
100% brand new and high quality
1-Channel relay module, with photoelectric isolation
The module can be high or low by a jumper setting trigger
With power and relay action indicator
The module Operating voltage: 12V
The module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A
module Description:
1, the module uses genuine quality relay, normally open interfaces Maximum load: AC 250V / 10A, DC 30V / 10A;
2, using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA;
3, the module voltageļ¼ 12V
4, the module can be set to trigger high or low with jumpers;
5, fault-tolerant design, even if the control line is broken, the relay will not operate;
6, the power indicator (green), relay state indicator (red)
7, user-friendly interface design, all interfaces are available through the wiring terminal direct connection leads, very convenient
8, module size: 50mm x 26mm x 18.5mm (L x W x H)
9, with four mounting bolts holes, hole 3.1mm, 44.5mm x 20.5mm pitch
module interface:
1, DC +: positive power supply
2, DC-: negative one
3, IN: can be high or low level control relay
Relay outputs:
1, NO: normally open relay interfaces, relay before hanging, pull back with COM
2, COM: Relay Common Interface
3, NC: normally closed relay interfaces, relay before with COM, pull vacant post
High and low end of the trigger selection:
1. jumper LOW LOW trigger short-circuited;
2. When the trigger is high with high short jumper.
