Description
B&R 8MSA3M.R0-42 Product Specification
The B&R 8MSA3M.R0-42 is a high-performance digital input module designed for industrial automation systems, offering reliable signal acquisition and seamless integration with control platforms.
1. Product Description
The B&R 8MSA3M.R0-42 is a modular I/O solution engineered to interface with sensors, switches, and discrete devices in manufacturing, energy, and process control environments. It supports multiple digital input channels (configurable per application) and processes signals such as ON/OFF status or pulse triggers. The module features standard industrial communication protocols (e.g., Profinet, Modbus) for real-time data exchange with PLCs or HMIs. Its robust design ensures stable operation in harsh conditions, including high temperatures, vibrations, and electrical noise.

- Process Control: Manages valve positions and level indicators in chemical facilities.
Case Study: A food processing plant used the B&R 8MSA3M.R0-42 to monitor 200+ sensors across 25 modules. The system reduced downtime by 25% through real-time fault detection.

5. Competitor Comparison
- Higher Channel Density: Supports up to 64 inputs per rack compared to typical 32-channel limits.
- Faster Response Time: 1 ms signal processing vs. 2–3 ms in comparable products.
- Lower Power Consumption: <50 mA per channel for energy-efficient operation.
6. Selection Recommendations
- Channel Requirements: Choose based on the number of digital devices to monitor.
- Protocol Compatibility: Ensure alignment with your PLC’s communication standards.
- Environmental Demands: Pair with IP67-rated enclosures for outdoor or dusty environments.
7. Precautions
- Installation: Follow B&R’s guidelines for DIN-rail mounting and wiring.
- Voltage Stability: Use a regulated power supply to avoid signal distortion.
- Software Configuration: Calibrate input thresholds via Automation Studio.
