Description

1MRB150005R0001 is a digital input module (DI module) of the AC500 series PLC from ABB. Its core function is to collect binary switch signals from industrial sites (such as sensor on/off states, button statuses, etc.) and transmit them to the control system. It is a key component connecting field devices to upper-level control units. The following is detailed product information:

Core Product Positioning and Affiliation

1. Product Type: Industrial-grade digital input module (DI module), model associated with the AC500 series “500DI” standard I/O modules, with “1MRB150005R0001” as the official unique material number.

2. Series Affiliation: Part of ABB AC500 programmable logic controller (PLC) modular I/O family, compatible with the full range of AC500 CPU modules (such as PM554, PM564, PM573, etc.) and expansion racks, supporting both distributed and centralized I/O architectures.

3. Core Function: Receives field passive/active switch signals (such as limit switches, proximity sensors, emergency stop buttons), converts physical on/off states into digital signals (0/1) recognizable by the control system, enabling real-time monitoring of equipment status and triggering of logic control.

Core Functions and Features

1. High-Density Signal Acquisition: Provides multiple independent input channels, supporting parallel acquisition of signals from multiple field devices. It meets the signal monitoring needs of small to medium-sized automation systems and reduces module space occupancy.

2. Wide Compatibility Design: Compatible with dry contact (passive switch) and wet contact (active sensor) inputs, supports 24V DC industrial standard power supply, and can directly interface with NPN/PNP type sensors (some versions require software polarity configuration) without additional adaptation components.

3. Strong Anti-Interference and Reliability: Electrical isolation design is used between channels and between channels and the backplane (isolation voltage ≥ 2.5kV AC), combined with hardware filtering circuits to resist strong electromagnetic interference from motors and frequency converters in a factory workshop; industrial-grade component selection ensures long-term stable operation.

4. Ease of Use and Maintenance Convenience: – Modular compact structure, suitable for 35mm DIN rail installation, flexibly combinable with AC500 series power, output, and communication modules; – Panel equipped with LED indicators (power light + status light for each channel) clearly shows module power and channel signal status, enabling quick identification of wiring or device faults; – Spring-type tool-free terminals support 0.5~1.5mm² wires, ensuring efficient and secure wiring.

5. Flexible Configuration and Diagnostics: Compatible with ABB Automation Builder configuration software, allows configuration of channel filter times (e.g., 1ms/5ms/10ms) to filter high-frequency interference; supports self-diagnosis for channel disconnection, overvoltage, and other faults, with fault information fed back to the CPU via the bus for convenient remote monitoring.
