Description
A 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 voltage is 12 V;
4. the module can be set to high or low triggered by jumper;
5. fault-tolerant design. even if the control line is broken. the relay will not operate;
6. the power indicator (green). relay status indicator (red)
7. interface design humane. all interfaces can be connected directly via terminal wiring leads. very convenient
8. module size: 50mm * 26mm * 18.5mm (L * W * H)
9. has four mounting bolts holes. hole 3.1mm. 44.5mm * 20.5mm pitch
Two module interface:
1. DC +: positive power supply (voltage required by the relay. there 12V)
2. DC-: negative power connection
3. IN: can be high or low level control relay
Relay outputs:
1. NO: normally open relay interface. the relay before the vacant after the pull shorted with COM
2. COM: Common Interface Relays
3. NC: normally closed relay interface relay shorted with COM ago. after the pull-vacant
High and low level trigger selection ends:
1. when jumper short circuit with LOW is low lever trigger;
2. When jumper short circuit with high is high lever trigger.
