FC-IOCHAS-0002R - System Power Supply

Description

The switching input module is the processing module of the external control signal or field detection signal to the PLC CPU, and the external signal is generally the button, the proximity switch, the travel switch, etc. The output module is the PLC according to the input module input signal and internal logic programming logic processing, after processing the result, the switching output will be output by the output module high and low level signal, drive the external intermediate relay, contactor, indicator light, solenoid valve and other components, and then make the external equipment to carry out the corresponding action The role of the output module The function of PLC output module is to amplify the power of the output signal. The PLC signal is expressed by the level, so that it does not distort in the process of being read out, it needs to have a certain reserve energy or a certain signal power. The function of the output module is actually a power amplifier. The output module is what drives the external load. Common PLC output devices are transistors, thyristors, relays. The PLC input module is used to receive the various parameters of the production process. (start stop) The PLC output module is used to send out the information obtained after the operation of the programmable controller, and complete all kinds of control of the industrial site through the actuator outside the machine. (Execution results with output) 1. Have good anti-interference ability. 2. It can meet the matching requirements of various signals in industrial sites.

PLC digital output type plc switching output types are roughly divided into three types, relay output type, transistor output type and thyristor output type. R-relay; t-transistor Relay output AC DC can be, the transistor common 5vdc and 24vdc output, thyristor is relatively rare, only special output models have. Considering the type of output module selected, usually the relay output module has low price, wide voltage range (can be connected to the mains), large load capacity, small on-voltage drop, strong ability to withstand instantaneous voltage and overcurrent, but short life, long response time, slow action speed and so on. Transistor output (can be divided into PNP, NPN type) has the advantage of fast on-off speed (pulse output, suitable for high frequency), generally about 0.2ms; Long life; The disadvantage is low working voltage (can not be connected to the mains); The load capacity is weak, about 300mA. Thyristor output module is suitable for DC load, frequent switching, fast reaction speed, long life, low inductive power factor load, but the price is more expensive, the overload capacity is poor.

The company focuses on DCS, PLC, robot, large servo four systems
