1MRK002246-BD: Product Overview
The ABB 1MRK002246-BD is a 16-channel analog input module designed for seamless integration into ABB’s System 800xA automation platform. As a critical component for signal acquisition, it enables industrial systems to measure and monitor a wide range of physical parameters—including temperature, pressure, flow, voltage, and current—with high precision and reliability.
Role in Automation Systems:
Positioned as a front-end signal processing unit, the 1MRK002246-BD acts as an interface between field devices (e.g., sensors, transducers) and the System 800xA controller. It converts analog signals from field devices into digital data, which is then transmitted to the controller for real-time analysis, control, and visualization. This role is pivotal for applications requiring accurate process monitoring, such as power generation, chemical processing, and manufacturing.
Core Functionality:
-
Universal Input Support: Accepts multiple signal types, including 0–10V, 0–20mA, 4–20mA, and 0–50mV, eliminating the need for separate modules for different signal types.
-
High-Resolution Sampling: With 16-bit resolution, the module captures subtle changes in analog signals, ensuring precise measurement of process variables.
-
Isolated Inputs: Each channel is electrically isolated to prevent noise and interference from affecting signal integrity, a critical feature for harsh industrial environments.
-
Fast Sampling Rate: Supports up to 100 samples per second per channel, enabling real-time monitoring of dynamic processes.
Platform Benefits (System 800xA):
The 1MRK002246-BD leverages the scalability and flexibility of ABB’s System 800xA platform, which is designed for large-scale industrial automation. Key benefits include:
-
Seamless Integration: Compatible with other System 800xA components (e.g., controllers, I/O modules, HMI), reducing integration complexity.
-
Scalability: Supports up to 16 channels per module, allowing users to expand their system as needed without replacing existing hardware.
-
Diagnostics: Built-in diagnostic tools monitor channel health, signal quality, and power supply status, simplifying maintenance and troubleshooting.

Core Features & Customer Value
1. Universal Input Flexibility:
The 1MRK002246-BD’s ability to accept multiple signal types (voltage, current, resistance) reduces the need for specialized modules, simplifying inventory management and system design. For example, a chemical processing plant can use the same module to monitor temperature (via RTDs), pressure (via transducers), and flow (via vortex meters), streamlining maintenance and reducing costs.
2. High Precision for Critical Applications:
With 16-bit resolution and ±0.05% accuracy, the module delivers precise measurements even for small signal variations. This is critical for applications like power generation, where accurate monitoring of generator voltage and current ensures grid stability. For manufacturers, precise temperature control using the module can improve product quality and reduce waste.
3. Isolated Inputs for Harsh Environments:
Electrical isolation between channels and ground prevents noise from machinery, motors, or other sources from corrupting signals. This ensures reliable data transmission in industrial settings, where electromagnetic interference (EMI) is common. For example, in a steel mill, the module can accurately measure the temperature of molten metal despite high levels of EMI from nearby equipment.
4. Fast Sampling for Real-Time Control:
The module’s 100 samples/second per channel sampling rate enables real-time monitoring of dynamic processes. In a water treatment plant, this allows operators to adjust chemical dosing immediately based on pH or turbidity readings, ensuring compliance with environmental regulations. For robotics applications, fast sampling supports precise motion control by providing up-to-date feedback from sensors.
