Teyleten Robot 1 Channel Relay Module with Optocoupler Isolation Support High and Low Level Trigger Expansion Board 5V 3pcs
Two module interface. 1、DC+:Connect the positive pole of the power supply (voltage according to the requirements of the relay) 2、DC-: connected to the negative pole of the power supply 3, IN: can be high or low level control relay suction Relay output: 1、NO:Normally open relay interface, the relay is suspended before the relay is engaged, after the relay is engaged, it is shorted to COM. 2、COM:relay common interface 3、NC:Normally closed relay interface, shorted to COM before the relay is engaged, suspended after the relay is engaged. High and low level trigger selection terminal: 1. Low level trigger when jumper is shorted to LOW. 2. High level trigger when jumper is shorted to HIGH.
Product Features
- The module adopts high quality relay, normally open interface maximum load: AC 250V/10A, DC 30V/10A;.
- The use of chip optocoupler isolation, drive ability, stable performance; trigger current 5mA;
- The module can be set through the jumper high level or low level trigger;
- Fault-tolerant design, even if the control line is broken, the relay will not act;
- Power indicator (green), relay status indicator (red)
- Interface design humane, all interfaces can be directly connected through the terminal leads, very convenient
