Product Overview
The Allen-Bradley 1794-0B16P/A FLEX I/O™ 24V DC Sinking Input Module delivers robust digital signal acquisition for industrial control systems. Designed for Rockwell Automation's modular FLEX platform, this 16-channel module features IP67-rated epoxy-sealed construction (-40°C to +70°C) to endure washdowns, dust, and chemical exposure.
Critical Technical Specifications
- Input Voltage: 10-30V DC (4mA typical @ 24V DC)
- Input Type: Sinking (current flows to ground)
- Response Time: ≤1ms (software-adjustable filters)
- Isolation: 500V AC channel-to-backplane (reinforced isolation per IEC 61131-2)
- Surge Immunity: 1.5kV per channel (IEC 61000-4-5)
- Power Consumption: 70mA @ 5V DC backplane; 0.4W per point
- Certifications: UL 61010-1, ATEX/IECEx Zone 2, SIL 2 (IEC 61508)
- EMC: EN 61326-3-1 (4kV ESD, 3V/m RF immunity)
- Termination: 0.5-2.5mm² (20-14 AWG) via 1794-TB3/B screwless connectors
Targeted Applications
- Automotive Assembly: Robotic tooling position verification in IP67 environments
- Packaging Machinery: Photoelectric sensor interfacing for fill-level detection
- Material Handling: Conveyor jam detection with vibration-tolerant inputs (5g @ 55Hz)
- Water/Wastewater: Pump station float switch monitoring (NEMA 4X corrosion resistance)
- Food & Beverage: EHEDG-compliant washdown zone limit switch inputs
- Renewable Energy: Wind turbine blade pitch feedback in marine-certified (DNV-GL) systems
- Safety Systems: SIL 2-certified E-stop chains without external relays
Competitive Advantages
- Density Leadership: 16 channels in 35mm DIN width (50% smaller than rivals)
- Diagnostic Precision: Per-channel status LEDs detect wiring faults within 10ms
- Safety Integration: SIL 2 functional safety certification with no external barriers
- Wiring Efficiency: Plug-and-play 1794-TB3/B connectors reduce installation time by 60%
- Extreme Durability: Operates under sustained vibration (5g) and condensation (>95% RH)
- Legacy Migration: Compatible with existing 1794-TBNF terminals for cost-effective retrofits
- Studio 5000® Optimization: Pre-tested AOI blocks simplify SIL 2 verification
Functional Capabilities
- Configurable Filtering: Adaptive 0.1-16ms noise rejection for mechanical contacts
- Input Mirroring: Redundant data mapping to backup controllers via produced tags
- Startup Diagnostics: On-initiation short-circuit detection (<100µs response)
- Cold Junction Compensation: Built-in thermistor for ambient temperature drift correction
- Voltage Threshold Adjustment: Software-defined ON-state levels (15-25V DC)
