The module uses a genuine quality relay with normally open interfaces. Maximum load: AC 250V/10A, DC 30V/10A.

It uses an SMD optocoupler isolator, with driving capability and stable performance. Activation current 5mA.

The module voltage is available in 5V, 9V, 12V, 24V.

The module can be set to activate with a high or low signal via jumper.

Fault-tolerant design, even if the control line is broken, the relay will not operate.

Power indicator (green), relay status indicator (red).

The interface design is human-centric, all interfaces can be connected directly via terminal wires.

Module size: 50mm * 41mm * 18.5mm (L * W * H).

It has four mounting holes, diameter 3.1mm, 44.5mm * 35.5mm pitch.

Module Interface:

• DC +: positive power supply (voltage required by relay, options are 5V, 9V, 12V, and 24V).
• DC-: negative power supply.
• IN1: channel 1 signal for activation, can be set for high or low level relay control.
• IN2: channel 2 signal for activation, can be set for high or low level relay control.

Relay Outputs:

• NO1: normally open relay interface, floats before use, contacts with COM1.
• COM1: common relay interface 1.
• NC1: normally closed relay interface 1, contacts with COM1 before and after use.
• NO2: normally open relay interface 2, floats before use, contacts with COM2.
• COM2: common relay interface 2.
• NC2: normally closed relay interface 2, contacts with COM2 before and after use.

High and Low Signal Activation Options:

• S1 is the high or low signal selection for the relay.
• S2 is the high or low signal selection for the dual relay activation.
• When com and low are shorted, the related relay activates with a low signal.
