▼ Features :-
SMD optocoupler isolation
Good in safety. In power system and high voltage system, the lower current can control the higher one, able to control
various appliances and other equipment with high-current current.
Standard interface that can be controlled directly by microcontroller
(Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).
Green indicator LEDs for Power status
Red indicator LEDs for Relay output status.
With a normally-open (NO) and a normally-close (NC) contact.

▼ Pinouts
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
Rated current of the interface is 16A
