• Module description: 1 The module adopts genuine high quality relay, the maximum load of the usually open interface: AC 250V/10A, DC 30V/10A; 2 Using double optocoupler isolation, strong pressure capability, secure performance; set off recent 5mA; 3 Each channel of the module would be caused through jumper excessive or low level; four Fault-tolerant design, although the control line is broken, the relay will not move; five Power indicator (green), 1 relay repute alerts (red) 6 User-friendly interface design, all interfaces would be immediately connected during the wiring terminals, very convenient Module interface: 1 DC+: Connect to the high quality pole of the power supply (voltage is relay 5V) 2 DC-: Connect to the detrimental pole of the flexibility delivery 3 : The relay can be controlled by way of excessive or low point Relay output: 1 NO: Relay usually open interface, before the relay is vacant, it will likely be shorted to COM after selecting up 2 COM: Relay Common Interface three NC: Normally closed relay interface Before the relay is closed, it's short-circuited with COM High and low point trigger selection: 1 S1 is the high and low point set off number of relay 1; 2 When com is shorted to low, the corresponding relay is a low point set off When com is shorted to high, it's a excessive point set off Note: 1 to the various visual display unit and light-weight effect, the actual coloration of the article is probably barely varied from the colour which is showed at the photos 2 forgive 1 cm/0"-3 cm/1" measuring deviation due to manual dimension
