Relay and contactor working status indication circuit b
Source: InternetPublisher:D先生 Keywords: Relay BSP indicator light Updated: 2021/10/15
In order to indicate the working status of relays and contactors, the circuit shown in Figure 13-54 can be used . When the relay and contactor
are closed, the indicator light is on; when they are released, the indicator light is off.
The resistance value of resistor R can be determined experimentally.
