12 v 30 A type A (normally open) optical coupling isolation relay module

12 v 30 A type A (normally open) optical coupling isolation relay module

1.On board EL817 photoelectric coupler with photoelectric isolating anti-interference ability strong.

2.On board 12 v,30 a / 250 vac,30 a / 30 VDC relays,the relay long life can absorb 100000 times in a row.

3.Module can be directly and MCU I/O link,with the output signal indicator.

4.Module with diode current protection,short response time.

5.Module is normally open (NO) output,impermanence closed (NC) output.

6.PCB size: 34 (mm) x39 (mm).
