Honeywell 51109693100B | I/O module

Core Function & Technical Overview

Key Features

• Presumed to include 16–32 discrete input/output channels, supporting both dry contact (no voltage) and wet contact (24 VDC/125 VDC) signals, or analog signals (4–20 mA/0–10 V).
• High-speed signal sampling (estimated 1–10 ms per channel) to capture transient events (e.g., emergency stop triggers) in safety-critical loops.
• Compatible with system-wide I/O expansion, supporting up to 1000–2000 points when paired with DCS racks.

• Presumed to integrate with controllers via Local Control Network (LCN) or Modbus protocol, with a transmission rate of up to 1 Mbps for seamless data exchange with operator stations.
• Equipped with diagnostic ports for troubleshooting via Honeywell Engineering Workstation software.

• Extended operating temperature range (presumed -40°C to +70°C) for harsh industrial environments (e.g., high humidity, dust).
• Presumed to feature 2.5 kV galvanic isolation (channel-to-channel, channel-to-ground) to resist interference from high-voltage equipment.
• Shock-resistant (estimated 50 G peak) and vibration-tolerant (2.5 G RMS), compliant with IEC 60068-2 standards.

• Configurable via Honeywell Engineering Workstation for channel mapping, signal scaling, and debounce settings (0–100 ms).
• Presumed to support IEC 61131-3 standards for compatibility with modern programming tools.

Technical Specifications

Key Design Features

• Presumed to be rack-mounted in TDC 3000 or Experion PKS 10-slot chassis, supporting up to 8 modules per rack for scalable I/O expansion.
• Likely hot-swappable, allowing replacement without system shutdown to reduce maintenance downtime.

• Optional dual power supplies for fail-safe operation in mission-critical applications.
• Built-in self-test (BIST) with LED indicators (power, fault, channel activity) for real-time diagnostics.
