2 Channel DC 5V Relay Module 30A optocoupler isolation module High and Low Level Trigger Relay for Smart Home PLC

Feature:

Using double-sided FR-4PCB board

Using high-power relay, control the load up to 30A

With each optocoupler isolation, anti-interference ability

Black 9500 terminals, more convenient for high-current wiring

Each circuit has a relay on LED indication

The modules comply with international safety standards with isolation slots in the control and load areas

Applications:

PLC automation equipment control, industrial system control, internet of things control, home intelligent control, electronic hobbyist development experiment, all kinds of circuit modification

Trigger voltage range

5V low trigger module: 0-2VDC relay on (ON), 3-5VDC relay off (OFF)

5V high trigger module, 3.3-5VDC relay (ON), 0-2.5VDC relay off

Module interface:

1.DC +: module DC power supply positive (trigger terminal voltage positive)

2.DC-: module DC power supply negative (trigger terminal voltage negative)

3.IN: signal trigger terminal (the default trigger voltage and power supply the same)

4. High / low level trigger mode selection, as shown, jumper and L-side connection, IN-side low-level trigger, connected with the H-side high trigger

5. NC (NC): normally closed relay

6. Common (COM): Relay Common

7. often open (NO): relay normally open
