Honeywell 10100/2/1 Horizontal Bus Driver Module
The Honeywell 10100/2/1, also cataloged as the 10100/2/1 Horizontal Bus Driver, operates as a dedicated hardware component for high-speed rack-to-rack data bus driving and signal regeneration within Honeywell Safety Manager and Fail Safe Controller (FSC) architectures.
Suffix Breakdown & Model Matrix
The catalog numbering structure defines specific hardware revision and subsystem compatibility parameters:
- Base Part Number (10100): Identifies the core FSC/Safety Manager system horizontal bus driver printed circuit assembly.
- Variant Qualifier (/2/1): Designates the dual-channel driver configuration tier optimized for standard 3U rack backplane interfaces.

Process Control & DCS Signal Interfacing
Configured for high-integrity inter-rack communication in Honeywell DCS and safety platforms, the Honeywell 10100/2/1 (10100/2/1 Horizontal Bus Driver) provides direct physical/electrical execution. It buffers logic-level signals transmitted across chassis backplanes, utilizing channel-to-channel isolation and differential drivers to suppress cross-talk and common-mode noise. The onboard driver circuits ensure deterministic bus timing across extended cable lengths while maintaining stable 5 VDC logic levels within specified power ripple limits.
Frequently Asked Questions
Q: How do different interconnection cable types (A1, A21, A22) affect the current draw of the 10100/2/1 module?
A: Interconnecting via A1 or A21 cables imposes a 35 mA current load on the internal 5 VDC backplane supply, whereas utilizing higher-capacity A22 bus cables increases logic current consumption to 65 mA.
Q: What are the consequences if backplane 5 VDC supply ripple exceeds the 50 mV p-p limit?
A: Exceeding 50 mV peak-to-peak power ripple may induce logic timing jitter across high-speed bus drivers, triggering diagnostic parity errors or communication retries on the horizontal bus.
Field Installation Guidelines
Mount the 10100/2/1 module into a standard 3U (3 HE), 4 HP (4 TE) card slot in the system rack chassis. Verify that all system power supplies are deactivated before seating the module into the backplane connectors to prevent pin damage or electrical arcing. Fasten the front-panel captive retention screws to ensure chassis ground continuity and mechanical stability under vibration. All interconnecting bus cables (A1, A21, or A22) must be securely locked into their corresponding header connectors, and cable drain wires must terminate directly to the cabinet earth bus bar.
