4 Channel Relay Module 24V High and Low Level Trigger Relay Module

This 4-Channel Relay Module 24V High and Low-Level Trigger Relay Module comes with max Load for Output: AC 250V/10A, DC 30V /10A. 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 24V Relay Module, the 12V 4-Channel Relay Module, and the 24V 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 to control. 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+: 24V positive power supply
2. DC-: 24V 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

Note: The actual product may vary in slight variation in color and components with the image shown depending upon quantity availability.
