Available Options

Module description:


The module uses genuine high-quality relays, the maximum load of the normally open interface: AC 250V / 10A, straight 30V / 10A;

SMD optocoupler isolation, strong driving ability and stable performance; trigger current 5mA;

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

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

User-friendly interface design, all interfaces can be directly led out through terminal blocks, which is very convenient


Two module interface:

1. DC +: Connect to the positive pole of the power supply (3.3V)

2. DC-: connect to the negative pole of the power supply

3. IN: Low-level control relay pull-in


Relay output:


1. NO: Normally open interface of the relay. The relay is suspended before pull-in, shorted to COM after pull-in.

2. COM: Relay common interface

3. NC: relay normally closed interface, the relay is short-circuited to COM before pull-in, and left floating after pull-in
