Honeywell FSC 10100/2/1 Horizontal Bus Driver Module

The Honeywell FSC 10100/2/1 Horizontal Bus Driver Module is a critical communication interface module used in Honeywell’s Fail Safe Controller (FSC) platform. Designed to ensure safe and reliable horizontal communication between logic solvers or subsystem nodes within an FSC-based Safety Instrumented System (SIS), this module is pivotal in the high-integrity safety architecture demanded by the process industries.

In large-scale or distributed safety configurations, the 10100/2/1 module supports deterministic communication across horizontally arranged controllers, maintaining synchronicity, signal accuracy, and system-wide fault tolerance. It is particularly suited for SIL 3 certified environments and provides redundant operation for enhanced system availability. The module operates seamlessly with Honeywell’s FSC system infrastructure, commonly used in refineries, offshore platforms, chemical plants, and power facilities.

• Petrochemical and Chemical Plants

  Provides horizontal linkage for distributed logic solvers, essential for process safeguarding and interlocking mechanisms.

• Power Generation Facilities

  Used in turbine safety, boiler management systems (BMS), and plant-wide protection strategies.

• Refineries

  Ensures consistent safety communication between modular shutdown units and control panels.

• Pharmaceuticals

  Supports validated and redundant data transmission for cleanroom or hazardous zone applications.

• LNG Terminals and Storage

  Ensures synchronized horizontal safety logic in distributed liquefaction, compression, or vaporization systems.
