Description

1. The module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A;
2. Using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA;
3. The module Operating voltage 5V;
4. The module can be high or low by a jumper setting trigger;
5. Fault-tolerant design, even if the control line is broken, the relay will not operate;
6. The power indicator (green), the relay status indicator (red)
7. The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient
8. Module size: 50mm * 26mm * 18.5mm (L*W*H)
9. Mounting hole size:44.5mm * 20.5mm (L*W);Has 4 mounting bolts holes , hole 3.1mm,

Trigger voltage range:
DC 05V: Low-level trigger: 0-1.5V relay ON; 2.5-5V relay OFF;
High-level trigger: 2.5-5V relay ON; 0-2V relay OFF;

Module interface:
1. DC+: positive power supply (VCC) ;
2. DC-: negative power supply (GND);
3. IN: can be high or low level control relay;
4. S, HIGHT OR LOW LEVER;
Relay outputs:
1. NO: normally open relay interface
