Description:
1. Maximum load: AC 250V/10A, DC30V/10A
2. SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA.
3. The module voltage 5V.
4. Each channel module can be set high or low triggered by jumper
5. fault-tolerant design, even if the control line is broken, the relay will not operate.
6. Power indicator (green), 2 relay state indicator (red).
7. Interface design user-friendly, all interfaces are available through the wiring terminal direct connection leads, very convenient.
8. Has four mounting bolts holes , hole 3.1mm, 44.5mm * 20.5mm pitch

Module Interface:
1. DC +: positive power supply DC 12V
2. DC-: negative power connection
3. IN1: 1 channel signal to trigger the end , you can set a high or low level control relay
4. IN2: 2 -channel signal to trigger the end , you can set a high or low level control relay

Relay Outputs:
1. NO1: After a relay normally open interfaces , relay before floating, shorted pull with COM1
2. COM1: 1 relay common interface
3. NC1: 1 relay normally closed port, COM1 relay shorted before and after the pull- vacant
4. NO2:way normally open relay interface, the relay before floating , pull back and COM2 short
5. COM2: 2 Common Interface relay
6. NC2: 2 -way normally closed relay interface relay short front and COM2 , pull vacant post

High And Low Level Trigger Option:
1. S1: It is option switch for channel 1 relay.
2. S2: It is option switch for channel 2 relay.

Note:
This relay will be triggered by DC 12V, can not trigger with signal at 5V.

Package Included:
5*DC 12V 2 Channel Relay Module With Isolated Optocoupler High and Low Level Tr
