2, using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA;
3, the module voltage is 5V, 9V,12 V, 24V are available;
4, the module can be set to high or low triggered by jumper;
5, fault-tolerant design, even if the control line is broken, the relay will not operate;
6, the power indicator (green), relay status indicator (red)
7, interface design humane, all interfaces can be connected directly via terminal wiring leads, very convenient
8, module size: 50mm * 26mm * 18.5mm (L * W * H)
9, has four mounting bolts holes, hole 3.1mm, 44.5mm * 20.5mm pitch
Two module interface:
1, DC +: positive power supply (voltage required by the relay, there 5V.9V.12V and 24V choice)
2, DC-: negative power connection
3, IN: can be high or low level control relay
Relay outputs:
1, NO: normally open relay interface, the relay before the vacant after the pull shorted with COM
2, COM: Common Interface Relays
3, NC: normally closed relay interface relay shorted with COM ago, after the pull-vacant
High and low level trigger selection ends:
1 when jumper short circuit with LOW is low lever trigger;
2 When jumper short circuit with high is high lever trigger.
