The input and output types of PLC are divided into digital input and output, analog input and output, and high-speed pulse input and output. You should know the digital analog quantity, the digital quantity is only 0 and 1 (the circuit is represented as on and off), the analog quantity is a current or voltage … Continue reading PLC digital output and relay output

plc transistor output vs relay output
Plc Transistor output vs Relay output1. Different load voltage and current typesLoad type: The transistor can only have a DC load, and the relay can be used with both AC and DC loads.Current: Transistor current 0.2A-0.3A, relay 2A.Voltage: The transistor can be connected to DC 24V (generally the maximum is about 30V DC, the relay … Continue reading plc transistor output vs relay output
What is the difference between Relay and Transistor outputs?
PLC transistor output response is fast, can be used for high-speed output, but control solenoid valve or need to add intermediate relay; relay output response is slow, but can save external relay, simple wiring. What output should be chosen depends on the load.Transistors are mainly used for position control, and they need to send pulses … Continue reading What is the difference between Relay and Transistor outputs?
