10100/2/1 | Honeywell Horizontal Bus Driver HBD Module

Product Overview

The Honeywell 10100/2/1 is a Horizontal Bus Driver (HBD) for the Honeywell FSC (Fail Safe Control) system. It drives the horizontal bus signals within I/O racks, enabling communication between the I/O backplane and the I/O modules, ensuring reliable data exchange in safety-critical distributed I/O configurations.

FAQ

Q: What is the difference between HBD and VBD?
A: The HBD (10100/2/1) drives the horizontal bus within I/O racks, while the VBD (10001/R/1) drives the vertical bus between the CP rack and I/O racks.

Q: Is the HBD required for every I/O rack?
A: Yes, each I/O rack requires an HBD for horizontal bus communication between the backplane and I/O modules.

Installation Guide

1. Power down the FSC I/O rack before installation.
2. Insert the HBD into the designated slot on the I/O backplane.
3. Verify backplane compatibility (10314/1/1 for non-redundant, 10315/1/1 for redundant).
4. Connect horizontal bus wiring per FSC system documentation.
5. Verify bus continuity using FSC diagnostic tools.

Selection Tips

• For non-redundant I/O racks, use backplane 10314/1/1 or 10318/1/1 with HBD.
• For redundant I/O racks, use backplane 10315/1/1 or 10317/1/1 with HBD.
• Ensure proper grounding of I/O racks for reliable HBD operation.
