Description
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 advantages of the high drive control line disconnection, the load will not work, as security.
Features:
- 5V relay
- Can be used as a microcontroller development board module can be used as a home appliance control
- 5 V-5v TTL control signals
- Control DC or AC signal can control the 220V AC load.
- A normally open and one normally closed contact
- A power indicator
- Control light, bright pull, disconnect does not shine
- The increase in transistor drive a relay coil, control pins high impedance.
