Honeywell 05701-A-0145 is a discrete input/output module PLC, which is one of the I/O modules of PLC (Programmable logic Controller). In the PLC system, the discrete input/output module is used to collect and output discrete signals, that is, digital signals. These signals typically represent switching states, such as on or off, or other discrete variables. The discrete input module is used to receive the discrete signal input, while the discrete output module is used to output the discrete signal and control the state of the external device. The Honeywell 05701-A-0145 module has a variety of functions and features. First of all, it can achieve fast and reliable signal transmission and processing to ensure the PLC system's accurate control and monitoring of external equipment. Secondly, the module has high reliability and can operate stably for a long time, reducing the need for failure and maintenance. In addition, it is easy to program and configure, users can set up and control according to their needs.

Digital/analog signal difference The digital input/output signal is the switching signal, 1 or 0, Analog signals, there are two, voltage or current signals, generally the signal transmitted by the transmitter, such as the pressure transmitter to detect the pressure of the water pipe, it will output an analog signal 4-20mA or 0-10V signal to the PLC, PLC for data processing. The switching input point (DI) processes the switching input signal. Analog input point (AI), processing analog input signals (0-20mADC,0-5VDC). Resistance signal (including thermal resistance) input point, processing thermal resistance or general resistance signal. High-speed pulse input point, processing high-speed pulse signal. Voltage (including thermocouple) input point, processing voltage input or thermocouple signal. There is also communication, which is used to exchange data with the upper computer or control the instrument driver of the lower controller

Digital/analog input module difference According to the difference of field input signal, the input module can be divided into switching input module and analog input module. The function of the switching input module is to convert various switching signals into TTL standard signals required by the CPU. According to the input power supply type, it can be divided into DC input module and AC input module. The input signal is converted into TTL (5V) standard signal by photoelectric coupling after voltage division, current limiting and filtering. The function of the analog input module is to convert the continuously changing analog signals such as temperature, flow, current, voltage, etc. into several digital signals that the CPU can process. The analog input circuit is generally composed of op amp conversion, mode conversion (A/D), photoelectric isolation, etc. 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
