ALLEN BRADLEY Electrical 1785-L20E processor module

Brand:Allen Bradley

MPN:1785-L20E

Type: Processor Module
Country of production: United States

The 1785-L20E quotation AllenBradleySLC500 is a small framework programmable logic controller. It also includes discrete, analog, special I/O modules, and related peripheral devices. The SLC500 controller has strong processing power, and its communication network, functional modules, and storage capacity can be flexibly selected and configured. RSLogix500 ladder diagram programming software provides a convenient editing and development environment, allowing users to configure I ≤ O modules by clicking and selecting with the mouse. At the same time, it is equipped with a powerful symbol database editor and fault diagnosis function, which can help developers save time and maximize production efficiency. Kunrui002
PLC has small size, light weight, and is easy to install. The input and output system of PLC can intuitively reflect the changing status of on-site signals and the operating status of the control system through various means, such as internal working status, communication status, I/O point status, abnormal status, and power supply status. There are some eye-catching explanations that are very beneficial for operation and maintenance personnel to monitor the system. The input signal types for the supply of programmable controllers in the 1785-L20E quotation can be switch quantity, analog quantity, and digital quantity. Generally speaking, the input unit consists of two parts: one is the interface circuit connected to the controlled device, and the other is the input image register.
The input unit receives various control signals from user devices, such as limit switches, operation buttons, selection switches, jump switches, and other sensors. Through the interface circuit, these signals are converted into signals that the central processing unit can recognize and process, coexisting with the input image register. At runtime, the CPU reads input information from the input image register and processes it, storing the processing results in the output image register.
In order to prevent various interference signals and high-voltage signals from entering the PLC, affecting its reliability or causing equipment damage, the on-site input interface circuit is generally isolated using optoelectronic coupling circuits. The key component of the optoelectronic coupling circuit is the optocoupler, which is usually composed of light-emitting diodes and optotransistors. The quotation for 1785-L20E usually includes PLC input types of DC (DC24V), AC and AC and DC. The power supply for the input circuit is provided externally. Some can also be provided internally by the PLC. For DC input, it is divided into two types based on the form of the field input interface circuit: source input and destination input. The vast majority of PLCs in Europe and the United States use leakage inputs, while the vast majority of PLCs in Asia use source inputs.
The PLC is connected to the control object through input/output terminals. The input and output terminals of PLC usually have three organizational forms, namely sink type, group type, and separate type. Most of the input terminals of PLCs adopt a sink type, while some PLCs adopt a group type to increase flexibility in use.
Collect temperature, pressure, and flow rate, and control the heating flow rate based on the collected data, achieving the goal of energy conservation. According to the changes in outdoor climate, adjust the opening of the electric valve in the original pipeline network to timely control the temperature return of the secondary pipeline network. By scheduling the given control curve, the operating parameters of each heat exchange station are within the given range. Colleagues, the central control room can remotely control and adjust operating parameters of the dispatched electric valves as needed. The gprs dtu system configuration can achieve temperature control and frequency conversion of filling remote control water pumps. The upper computer chooses to configure the King configuration software, which is combined with the database to store and analyze all data, and can cooperate with the optimization software for priority control.
