Fault tolerant designed, humanized lead wire terminals, even the control line break off, the relay still keep working.

Module Size: 50x26x18.5mm

4 Fixed Holes for Screw: Diameter 3.1mm

Quiescent Current: 5mA

Max Current: 190mA

Trigger Current: 3-5mA

Input Interface:

1. DC+: 5V positive power supply

2. DC-: 5V negative power supply

3. IN: corresponding with trigger signal level of relay

Output Interface:

1. NO: normally open interface

2. COM: common interface

3. NC: normally close interface

Normally Open Interface Work Mode:

COM port connect with loaded AC live line or DC positive power supply, NO port connects with loaded AC zero line or DC negative power supply, the load circuit is disconnected, when there is trigger signal iniput, relay pick up, and circuit connected, load work.

Normally Close Interface Work Mode:

COM port connect with loaded AC live line or DC positive power supply, NC port connects with loaded AC zero line or DC negative power supply, the load circuit is close, and load work normally. When there is trigger signal iniput, relay disconnect, and load is off work.

Voltage: 5V
