The module is triggered, high trigger current less than 5mA, part of the 51 single-chip IO port output capability is weak, pull or increase the drive capability of the circuit. The advantage of the high drive control line disconnection, the load will not work, as security.
The relay using the Song Yue relay, the output contact capacity 10A 250VAC, 10A 30VDC, easily used in home appliances, or industrial.
8 ways are high, namely high relay.
Each relay has normally open and normally closed contact.
8 ways, optically isolated, safe, reliable, high noise immunity.
Can be selected by jumper relay and TTL or ground.
With a power indicator. 8-way road has a status indicator
With the relay coil to absorb the diode protection.
VCC: 12V from power suplly
GND: 0V from ground
IN1: 1-input control signal
IN2: 2-input control signal
Terminals: connected to load
