This 4 Channel Relay Module 12V 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 open 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 12V Relay Module, 12V 4-Channel Relay Module, and 12V 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:
- DC+: 12V positive power supply
- DC-: 12V negative power supply
- IN: corresponding with trigger signal level of relay
Output Interface:
- NO: normally open interface
- COM: common interface
- NC: normally close interface
Package Includes: 1 x 4 Channel Relay Module 12V High and Low-Level Trigger Relay Module
