1. Interface

The input-output interface is the interface circuit connecting PLC with the industrial field control or detection element and the executive element. PLC input interface has DC input, AC input, AC DC input and other types; The output interface includes transistor output, thyristor output and relay output. The transistor and thyristor output are contactless output circuits, the transistor output is used for high frequency low power load, and the thyristor output is used for high frequency high power load. The relay output is a contact output circuit for low frequency loads.

Field control or detection element input to PLC a variety of control signals, such as limit switch, operation button, selector switch and some other sensor output switching or analog amount, through the input interface circuit will be converted into the CPU can receive and process signals. The output interface circuit converts the weak current control signal sent by the CPU into the strong current signal output required by the field to drive the actuator of the controlled equipment, such as the solenoid valve and contactor.

1) Input interface

The input interface is used to receive and collect two types of input signals, one is by button, transfer switch, travel switch, relay contact and other switch input signals; The other is the continuously varying analog input signals provided by potentiometers, velocimetry generators and various converters.

Take the DC input interface circuit shown in Figure 2 as an example, R1 is the current limiting and voltage divider, R2 and C constitute the filtering circuit, and the filtered input signal is coupled with the internal circuit through the optical coupler T. When the button SB at the input end is switched on, the optical coupler T is switched on, and the DC input signal is converted into the 5V standard signal level (TTL for short) that can be processed by PLC. At the same time, the LED input indicator lights up, indicating that the signal is switched on. The input interface circuit of microcomputer is generally composed of register, power selection circuit and interrupt request logic circuit, which are integrated in a chip. Ac and AC/DC input interface circuits are similar to DC input interface circuits.
