Mitsubishi A1SX41-S2 is an expansion digital input module for Mitsubishi Electric’s A-series PLC (Programmable Logic Controller). The specific details are as follows:
It belongs to the expansion digital input module of Mitsubishi A-series PLC, designed to collect external digital signals (such as the on/off status of switches, sensors, etc.).
- Number of Input Points: 16 points, capable of accessing 16 channels of digital input signals simultaneously.
- Input Type: DC input, typically supporting a DC 24V voltage supply (compatible with common industrial DC control circuits).
- Input Mode: Universal for sinking/sourcing types (specific details need to be confirmed with the manual), adapting to different wiring requirements in on-site applications (sinking type is suitable for NPN sensor signals, while sourcing type matches PNP sensor signals).
- Response Time: Generally less than 1ms, enabling rapid response to changes in external signals (suitable for scenarios requiring real-time signal capture, such as high-speed production line status monitoring).
Exclusively designed for Mitsubishi A-series PLC systems, it must be used in conjunction with the same-series CPU modules (e.g., A1SHCPU) and power modules (e.g., A1S61PN). It expands the system’s input capacity through a rack or backplane, allowing the PLC to connect more external switch devices and enhance on-site status monitoring capabilities.
- Industrial-Grade Design: Boasts strong anti-interference capabilities, enabling stable operation in complex electromagnetic environments such as factories (effectively resisting interference from motors, frequency converters, and other high-power equipment to avoid signal distortion).
- LED Indicators: Equipped with LED indicators for each input point, which intuitively display the on/off status of each input channel. This facilitates quick troubleshooting (e.g., identifying faulty sensors or disconnection issues by checking indicator status).
- Rack-Mounted Installation: Adopts a rack-mounted installation method, allowing seamless integration into the PLC system. It simplifies wiring and ensures neat arrangement of the entire control system, reducing on-site installation and maintenance workload.
- As an older module of the A-series, Mitsubishi’s A-series PLC has gradually been replaced by newer models such as the Q-series. Currently, this module is mainly used for maintenance and replacement of existing old systems (it is recommended to confirm compatibility with the original system before procurement).
- During wiring, pay attention to the power polarity and voltage range (strictly following DC 24V specifications). Incorrect polarity or overvoltage may cause permanent damage to the module.
This module is widely used in industrial automation control fields, such as production lines and mechanical equipment. It connects the switch signals of external devices to the PLC system, enabling logical control (e.g., triggering equipment start/stop based on switch status) and status monitoring (e.g., real-time tracking of whether a mechanical limit switch is activated), thus ensuring the stable operation of the control system.
