PLC Digital Signals Wiring Techniques. In Above Figure, a level switch is mounted to a vessel. The switch is monitored by a PLC digital input module. The circuit is powered through a circuit breaker (CB2) in an instrument power panel. The main power feed is brought to a marshalling panel, where the power is split, feeding multiple fused circuits.

Working of Contactor. Let us understand the working of a contactor.When the PLC digital output turns on, the relay is energized. The output contact (NO) of the relay becomes closed and passes a supply potential connected through its common terminal to the NO contact and then to the contactor pin.. This energizes the contactor and switches on the three …

As per the datasheet of the 5mm White LED, the Forward Voltage of the LED is 3.6V and the Forward Current of the LED is 30mA. Therefore, VS = 12V, VLED = 3.6V and ILED = 30mA. Substituting these values in the above equation, we can calculate the value of Series Resistance as. RSERIES = (12 – 3.6) / 0.03 = 280Ω.
