Description
SAFT-185-TBC Types of PLC input and output modules: digital input DI, digital output DO, analog input AI, analog output AO. Digital input and output are generally 24V. There are 4 kinds of analog quantities in 2 categories, and the 2 categories are voltage type and current type respectively. Voltage type has 0-10V and -10 to 10V. Current type mainly has 4-20MA,0-20MA. Then the module converts the analog quantity into A number between +32767 and -32768 through A/D conversion, and then implements the control. The function of the signal template is to convert various process i/o signals. The input signals are converted into digital quantities, which are easy for plc to identify, process and analyze. The output is converted into analog to various regulating mechanisms for execution, or the output is converted into a 2-bit do quantity to control some devices such as start, stop, on and off
SAFT-185-TBC
SAFT-185-TBC 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 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.
