The 1-channel H/L 5V optocoupler relay module is made with genuine quality relays and features normally open interfaces. It uses SMD optocouplers for electrical isolation, offering driving capability and stable performance.

The trigger setting can be adjusted via jumper, allowing operation at high or low level. The design is fault-tolerant, as even if the control line breaks, the relay will not activate.

It has a power indicator (green) and relay status indicator (red), while the interface design is user-friendly, with all interfaces available through direct connection with wire terminals.

Specifications:

• Maximum load: AC 250V/10A, DC 30V/10A

• Four mounting holes, diameter 3.1mm

Module interface:

• DC+: positive power supply (VCC)
• DC-: negative power supply (GND)
• IN: can control the relay at high or low level

Relay outputs:

• NO: normally open relay interface
• COM: common relay interface
• NC: normally closed relay interface

High and low level activation options:

• It is low-level activation when the jumper is connected to the LOW socket
• It is high-level activation when the jumper is connected to the HIGH socket

Package includes:

• 1 x 1-channel H/L optocoupler relay module
