1. the use of the original SMI type of double relay;

2. the input is two way to trigger, but there are four output;

3. the output of the relay has two public side, often beginning, often closed, and two independent work;

4. the use of high temperature resistance PA terminal, the quality is very good;

5. with a working state indicator relay;

6. with the SS8550 original transistor to do the switch tube, the big current is more quality assurance;

7.the low level of the module is triggered, that is, with DC negative trigger.

Electrical parameters:

1. there is 24v;

2. quiescent current: less than 5mA;

3. with load maximum power: 1.5W;

4. relay load capacity: 5A 250VAC (1250W exchange) or 5A 30VDC (150W);

5. relay the maximum life: 1000000 times.
