1MRK000508-CBr00 ABB Digital Input Module

Description

The 1MRK000508-CBr00 ABB Digital Input Module is a core signal acquisition component for industrial automation systems, designed to collect and process on-site switch status signals for integration with control systems like PLC, DCS, or PAC platforms. As a member of ABB’s digital input module lineup, it shares key industry-standard features: it receives on/off signals from field devices including buttons, limit switches, proximity sensors, and relay contacts, then converts these signals into data recognizable by central control systems.

Typical technical specifications for comparable ABB digital input modules include configurable input point counts (such as 4, 8, 16, or 32 channels), common input voltage ranges like 18 to 30 V DC, and input current draws around 6 mA at 24 V DC. Core functional features include electrical isolation via optical couplers to protect control systems from high voltage, noise, and ground potential interference; built-in filtering to eliminate signal jitter for stable data transmission; and channel status indicator lights for quick on-site diagnostics. Some models may also include grouped channel isolation and voltage monitoring inputs that trigger error signals via the module bus if power is lost.

This module is ideal for applications such as equipment running status detection, emergency stop signal collection, and sensor trigger monitoring in factory automation, building control, energy management, and transportation system environments, supporting real-time data transfer via backplane or field buses like Profibus, EtherCAT, or Modbus.
