1. With power supply reverse connection function to prevent damaging the module.
2. The module uses genuine relay, rated load of normally open interface: AC 250V/10A, DC 30V/10A.
3. Using small-sized two-way isolated optocoupler, with strong anti-interference ability and ; trigger current is only 5mA.
4. Users can select the control level of the relay, which can be high level pull-in or low level pull-in.
5. The module has built-in finite current resistor. The positive and negative pole control of the power supply can be used directly, or use the I/O port of the single-chip to control.

Specification:
Isolation Type 16 Channel Relay Module can select high-level or low-level triggering, and only needs 5mA current to drive the relay with 10A control capability to pull in.
The module adopts genuine power relay, small-sized package optocoupler, high-power high dielectric strength triode, red and blue indicator, double-sided PCB board, and with reasonable layout and , can be widely used in a variety pf control.
