The Honeywell 10100/2/1 Horizontal Bus Driver Module (HBD) is an essential component in industrial I/O rack configurations, ensuring seamless communication and address line termination. Designed with a robust architecture, it features an electronic module (10100/2/1) and a compatible flatcable (A1, A21, or A22), depending on the I/O configuration—non-redundant or redundant.

The Honeywell 10100/2/1 Horizontal Bus Driver Module connects the vertical bus flatcable from the Central Part to the I/O rack via the back connector CN1. It extends connectivity to the horizontal bus above the I/O rack and manages address selection lines through the connector CN3. It supports multiple configurations, including:

• A1 flatcable for non-redundant I/O,

• A21 flatcable for redundant I/O (single rack), and

• A22 flatcable for redundant I/O (dual rack).

Engineered for reliability, the module can be replaced while the power is on, though for safety-critical applications, system shutdown may occur. Its durable design ensures robust communication pathways in demanding industrial environments.

Key Features

• Seamless integration with I/O racks via vertical and horizontal bus connections.

• Compatible with non-redundant and redundant I/O configurations.

• Safe replacement under power, with automatic shutdown in safety-critical setups.

• Robust DIN 41612 male connector design with precise pin allocation for secure connections.
