4 Channel 5V Relay Module High and Low Level Trigger Relay Module with Optocoupler

This 4 Channel 5V Relay Module High and Low Level Trigger Relay Module with Optocoupler comes with a max load for output: AC 250V/10A, DC 30V/10A. A trigger current of 20 mA can be used to all kinds of single-chip microcomputer IO control triggering, normally opening and closing two work modes. By switching the trigger level selection terminal to set 3-5V high level or 0-1.5V low-level trigger controlled,

Adopting patch piece opto-isolator, green power light, red relay status light, strong drive capability, stable performance, and clear work conditions This product is known as the 4 Channel 5V Relay Module, the 12V 4-Channel Relay Module, and the 5V 4 Channel Relay Optocoupler Isolation Module.

Trigger Mode Configuration:

The module has a trigger level selection terminal; for each relay, the trigger level can be individually controlled through the short-circuit cap. The COM side is common, in the middle. When the LOW (L) terminal is connected to the common terminal, it is a low-level trigger; when the HIGH (H) terminal is connected to the common terminal, it is a high-level trigger.

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

Features:

• The 8550 transistor drive, driveability.
• A fixed bolt holes for easy installation.
• It has a relay status indicator led Power LED(Green), 1 relay status indicator LED(Red)
• Relay control interface by single-chip IO.
• Low-level suction close, high-level release.
• Easy to use, simple 3 line structure.
• 1-Channel Relay interface board,
• Equipped with high-current relay : 15A 125V AC or 10A 250V AC
• Standard interface that can be controlled directly by microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM).
