12V 5A single channel relay Optical coupling isolation Original Panasonic LKT1
1. Summarize
LC Relay-Panasonic relay module is a general power relay module based on Panasonic electromagnetic relay.
2. Functional Characteristics
-1:The on board EL817 photoelectric coupler with photoelectric isolating anti-interference ability is strong;
-2: The module can be directly and MCU I/O link, input signal trigger mode optional;
-3: With output indicator and diode module stream protection.
3. Introduce of hardware and instructions
Connection details:
VCC: input voltage (12 v);
GND: input voltage to end;
VIN: high level trigger terminal;
IN: low level trigger the end;
COM: output the public end.
NO: Relay and impending, after actuation short circuit with COM.
NC: The normally closed end, before actuation relay short circuit with COM, after actuation suspend in mid air.
Before using high level trigger manner, IN the need to connect with GND;
Before using low level trigger manner, VIN side need to pick up the voltage (3.6 V to 12 V)
Note: NO NC COM connection you must remember: do not use the L and N access to two of the three interfaces at the same time , otherwise it will short-circuit the danger.
Correct connection: COM can be used as the access point L (or N), NO (or NC) as L (or N) output.
