A 24V 30A 1-channel relay module with optocoupler is an electronic device that is used to control high-power electrical devices, such as motors, lights, or appliances. It consists of a relay, a control circuit, and a user interface, and is typically used to switch electrical devices on or off remotely, or to switch between multiple devices. The module is equipped with an optocoupler, which is an electronic component that uses an optical coupling mechanism to isolate the control circuit from the load being controlled. This can help to reduce electrical noise and interference, and can improve the reliability and safety of the system. The module is typically triggered by a low-power control signal, such as a voltage from a microcontroller or a switch. The H/L-trigger version of the module can be triggered by either a high or low level control signal. 24V 30A 1-Channel Relay Module with Optocoupler H/L Level Triger 30A relay module, normally open interface maximum load: AC 250V/30A, DV 30V/30A Optical coupling isolation, driving ability is strong, stable performance;Trigger current is 5mA Module can be set high level or low level trigger by the jumper Power indicator light (green), relay status indicator light (red) Module Size:50mm*33mm*24mm Technical parameters: Voltage version:24V The static current:5mA Working current:50mA Trigger current:2-4mA Module interface specifications: DC : DC power supply positive pole DC- :DC power supply negative pole IN : signal triggering pin JD : relay control voltage positive JD- : relay control voltage negative DC and JD shorted by jumper cap, DC- and JD- shorted with jumper cap, it is the same voltage between trigger terminal and relay control terminal High and low level trigger mode selection.Jumper and L pin connection, IN pin is low level triggerJumper and H pin connection, IN pin is high level trigger Normally closed pin (NC) : relay normally closed pin Common pin (COM) : relay common pin Normally opened pin (NO) : relay normally opened pin
