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 5v;
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.
