1794-OB16P - 16-Point 24VDC Isolated Output - Industrial Rugged Hot-Swap Digital Module

The Allen-Bradley 1794-OB16P FLEX I/O™ 16-Channel Sinking Input Module provides robust digital signal acquisition in harsh industrial environments. Designed for Rockwell Automation's modular FLEX platform, this IP67-rated module features epoxy encapsulation (-40°C to +70°C) that withstands high-pressure washdowns, oils, and corrosive chemicals. It supports 24V DC sinking inputs with 1.5kV integrated surge suppression (IEC 61000-4-5) per channel, preventing damage from inductive kickback.

• Studio 5000® Efficiency: Pre-tested Add-On Instructions (AOIs) cut validation time
• Thermal Resilience: Operates at 95% humidity (ISO 12944 C4 compliance)

• Adaptive Filtering: 0.1-16ms noise rejection for mechanical contact bounce
• Voltage Thresholding: Software-defined ON-state range (12-28V DC)
• Sequence-of-Events Logging: 1ms timestamp resolution for fault forensics
• Redundancy Support: Mirroring inputs to backup controllers via produced tags
• Hot-Swap Operation: Module replacement without system shutdown
• Startup Diagnostics: Detects wiring faults during initialization (<50μs)
• Load Monitoring: Measures per-point current for predictive maintenance
• Legacy Compatibility: DIP switches override factory settings for older sensors
