A kind of PLC host of three major parts

PLC in a robot control system are as follows: 1, input unit input unit eight by eight button, switch and 16 connectors, each with 16 input point of PLC. Change the switch or button on and off state, can be the host switch input needed quantity. 16 other dc connectors can be external or switch quantity input signal. 2, output, unit output unit is composed of 24 diode and 24 connector, which is linked with 24 output points of PLC. Light emitting diode is light, can be said output point state, users can get the output of the host information. 24 output connectors can be an external need to control other devices. Output of unit 4 side, lead to the panel respectively, of which only C4 with 3 v power supply. 3, the host has an external left 220 v power supply unit PLC/AV socket, as PLC working power supply. Built-in transformer, the output 3 v power supply, for the use of diode. Another 24 VDC and 24 GND PLC controller, leads to the panel for the external input devices, Such as sensors) Working power supply.
programmable control systems plc manufacturers is generally used to plc controller price.
