Sample text

Also, the starter coil’s overloads are wired in series with the coil. In a PLC wiring diagram, the PLC is connected to power lines L1 and L2 (see Figure 28). The field inputs are connected to L1 on one side and to the module on the other. The common, or return, connection from the input module goes to L2. The output module receives its power for switching the load from L1. Output terminal 030 is connected in series with the starter coil and its overloads, which go to L2. The output module also directly connects to L2 for proper operation.

This circuit will drive output 030, which controls the starter. If the start push button is pressed, output 030 will turn ON, sealing the start push button and turning the motor ON through the starter. If the stop push button is pressed, the motor will turn OFF. Note that the stop push button is wired as normally closed to the input module. Also, the starter coil’s overloads are wired in series with the coil. In a PLC wiring diagram, the PLC is connected to power lines L1 and L2 (see Figure 28).
