Relay 5V 30A 1 Channel  Module with Optocoupler High Low Level Trigger

The relay module uses an authentic quality mechanical relay and the industry's top quality subminiature two-way isolation optical coupling which gives you the strong anti-interference ability, and stable performance.

The user can choose the relay control level, can be a high level off, also can be low level and off. The Single-channel 5V 30A Relay Module Power Failure Relay contains a limited flow resistance, can directly use the power supply is negative control, you can also use the MCU I/O control.

The relay module equips a power indicator light (red), 1 road relay status indicator light (blue).With this relay, you can easily control electrical appliances, lights, etc.

Fault-tolerant design, even if the control line break, the relay will not move.

Module interface :

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

Features :

Optical coupling isolation, driving ability is strong, stable performance; Trigger current is 5mA

The module can be set high level or low-level trigger by the jumper

Rated current of the interface is 16A

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 trigger Jumper and H pin connection, IN pin, is the high-level trigger.
