Information About 1797-IBN16
The 1797-IBN16 is part of the Allen-Bradley FLEX Ex I/O family, engineered for intrinsically safe installations in Class I, II, III Division 1 and Zone 1 applications. It features a single group of sixteen NAMUR-compatible sinking inputs designed to interface with low-energy field devices commonly found in hazardous process areas. The module connects directly to intrinsically safe terminal bases such as the 1797-TB3 or 1797-TB3S, ensuring full compliance with explosion-protection requirements. With configurable input delay settings and extensive LED diagnostics, the 1797-IBN16 is well suited for precise monitoring and troubleshooting in distributed process control systems.
Key Features:
- Sixteen NAMUR-Compatible Inputs: Supports a full group of sinking, non-isolated input channels.
- Intrinsic Safety Ratings: Certified Ex ia / Ex ib for use in Class I, II, III Division 1 and Zone 1 hazardous locations.
- Configurable Delay Times: Selectable input delays from 1 to 33 ms to accommodate varying process requirements.
- Dedicated Diagnostics: Includes 16 yellow status LEDs, 16 red fault LEDs, and a green power indicator for clear channel monitoring.
- High Input Frequency: Supports up to 1000 Hz for rapid signal detection.
- Compatible Terminal Bases: Designed specifically for FLEX Ex bases 1797-TB3 and 1797-TB3S.
- Low-Current Signaling: On-state current of 2.1 mA and off-state current of 1.2 mA for NAMUR sensor compliance.
- Industrial Temperature Range: Operates from −20 °C to +70 °C with robust environmental tolerance.
The 1797-IBN16 delivers the reliability and precision required for intrinsically safe signal acquisition in hazardous-area process automation.
