Features:
✪ The module uses real high quality relay, the maximum load of normally open interface: AC 250V/10A, DC 30V/10A.
✪ With patch optocoupler isolation, strong driving ability, stable performance; tripping current 5mA.
✪ The module operating voltage is available in 5V.
✪ The module can be triggered by a jumper to set a high or low level.
✪ Fault-tolerant design, even if the control line is broken, the relay will not move.
✪ Operation indicator (green), relay status indicator (red).
✪ The interface design is user-friendly, all interfaces can be connected directly via the terminal block, which is very convenient. ✪ Module size: 50 mm * 26 mm * 18.5 mm (length * width * height).
✪ With 4 mounting screw holes, hole 3.1 mm, spacing 44.5 mm x 20.5 mm.

Two-module interface:
1.DC+: Connect the positive pole of the power supply (the voltage is selected according to the relay and there are options for 5 V).
2, DC-: Connected to the negative pole of the power supply.
3, IN: Can control the relay to pull high or pull low.

Relay outputs:
1, NO: normally open relay interface
2, COM: Common Interface Relays
3, NC: normally closed relay interface

High and low level trigger options:
It is a low-level trigger when the jumper is connected to the LOW pin
It is a high level trigger when the jumper is connected to the HIGH pin
