Allen-Bradley 1771-IMD/B High-Density AC/DC Input Module
The Allen-Bradley 1771-IMD/B is a versatile 16-point AC/DC input module engineered for PLC-5 control systems, delivering reliable signal acquisition across diverse industrial environments. This dual-voltage input card seamlessly interfaces with both AC and DC field devices, eliminating the need for separate modules and reducing panel space requirements.
Technical Specifications
- Input Points: 16 isolated AC/DC digital inputs
- Voltage Range: 85-132V AC / 85-140V DC
- Input Current: 7 mA typical @ 120V
- Response Time: 20 ms ON, 30 ms OFF (AC mode)
- Isolation: 1500V optical isolation per input group
- Compatibility: PLC-5 family (1771 chassis)
- Operating Temperature: 0 °C to 60 °C (32 °F to 140 °F)
- LED Indicators: Individual status per input channel
Industrial Applications
Power Generation: Monitor turbine protection systems, generator breaker status, and auxiliary equipment feedback in coal, gas, and nuclear facilities.
Oil & Gas Processing: Interface with pump motor starters, valve limit switches, and emergency shutdown circuits across upstream and downstream operations.
Manufacturing Automation: Capture conveyor interlocks, safety gate positions, and machine cycle signals in automotive, food processing, and packaging lines.
Water Treatment: Track pump run status, level switch inputs, and alarm conditions in municipal and industrial wastewater systems.
Key Advantages
Dual-voltage flexibility reduces spare parts inventory
High-density design maximizes I/O per chassis slot
Optical isolation protects PLC backplane from field noise
Hot-swap capability enables maintenance without system shutdown
Proven reliability in harsh industrial environments
Integration & Support
The 1771-IMD/B integrates seamlessly with RSLogix 5 programming software and supports online module replacement for minimal downtime. Field wiring terminates via removable terminal blocks (RTBs) for simplified installation and troubleshooting. Compatible with standard 1771 I/O chassis and redundant power supplies.
Ideal for retrofits, expansions, and new installations requiring robust AC/DC signal monitoring in legacy PLC-5 architectures.
