The 10100/2/1CC10900 HORIZONTAL BUS DRIVER is a specialized horizontal bus driver (HBD) module that serves as a critical communication interface within industrial control systems. This essential component is installed in I/O racks, where its primary function is to manage data flow between the central processing unit and various input/output modules. The module operates on a 5 VDC power supply with remarkably low current consumption, typically drawing between 35-65 mA depending on the connected flat cable type, which demonstrates its energy-efficient design.

The physical architecture of the Honeywell FSC SYSTEM 10100/2/1CC10900 consists of two main elements: the electronic processing unit and a choice of flat cables (A1, A21, or A22). These cables extend from the front of the module to connect with the horizontal bus above the I/O rack, while the back connector interfaces with the vertical bus flat cable from the Central Part. This dual-connection design enables the module to effectively bridge communication between different levels of the control system hierarchy.

Configuration flexibility is a key characteristic of the Horizontal BUS Driver 10100/2/1CC10900, as it supports multiple operational modes through different cable types. The standard A1 cable facilitates non-redundant I/O connections, while the A21 and A22 cables enable redundant I/O configurations for enhanced system reliability. This adaptability makes the module suitable for various application requirements, from basic control setups to mission-critical systems where redundancy is essential for continuous operation.

The installation and maintenance advantages of the 10100/2/1CC10900 HONEYWELL include its compact form factor requiring only 4TE/3 HE space and lightweight design at 0.11 kg. Notably, the module supports hot-swapping capability, allowing replacement without system shutdown, though caution is required as removal may trigger central part shutdown for safety-related functions. The proven reliability and versatile application of the Honeywell 10100/2/1CC10900 IN STOCK make it an indispensable component for ensuring robust communication within complex automation architectures.
