Feb 6, 2020 · What is Input Module? The module which interacts with the input signal is called as Input Module. It is required to connect input devices like different types of switches.
Nov 19, 2023 · The input module, often referred to as the input card, handles the reception of signals from different sensors or devices linked to the PLC. This can include proximity sensors, switches, temperature sensors, flow meters, and more.
Input modules convert signals from sensors or other input devices into a format that the control system can process, while output modules convert control signals from the control system into signals that can activate actuators or other output devices.
Sep 17, 2024 · If your facility or workplace uses a PLC, it’s almost certainly because it must interface with physical input and output devices. What kinds of I/O modules exist, and how can you tell the difference?
Jul 14, 2024 · The input module of PLC has four main functions. The input module interface receives the signal from process devices at 220 V AC; Converts the input signal to 5 V DC that can be used by PLC; Isolator block is used to isolate/prevent PLC from undergoing fluctuation; After which the signal is sent to the output end i.e. the PLC
