Honeywell 10100/2/1 Horizontal Bus Driver Module

The Honeywell 10100/2/1, also cataloged as the 10100/2/1 Horizontal Bus Driver Module, operates as a dedicated hardware component for connecting vertical bus architecture to horizontal I/O buses within Honeywell Fail Safe Control (FSC) systems.

Hardware Specifications

Channel-To-Channel Isolation And DCS Protocol Integration

The module coordinates communication integrity by maintaining strict signal paths between the central controller and distributed I/O racks. Operating within Honeywell DCS and safety frameworks, it incorporates channel-to-channel isolation boundaries to mitigate electrical noise propagation. Signal attenuation is minimized through regulated 5 VDC feed delivery, ensuring that ripple content remains below the 50 mV threshold across extended flat-cable assemblies such as A1, A21, and A22 configurations.

Frequently Asked Questions

Q: What are the current consumption variations when switching between A1 and A22 cable configurations?

A: The module draws 35 mA of current when utilizing A1 or A21 single-rack cabling, whereas deployment with the A22 dual-rack cable configuration increases power draw to 65 mA at 5 VDC.

Q: Does the module support hot-swapping during live system operation?

A: Live insertion or removal requires adherence to safety control system procedures and rack power isolation protocols to prevent backplane bus disruption or data corruption on the horizontal bus.

Field Installation Guidelines

• Ensure rack power is fully isolated before seating the module into the DIN 41612 Type F rear interface connector.
• Verify that mechanical dimensions match the target enclosure slot prior to physical insertion.
• Route communication cables away from high-voltage power lines to minimize electromagnetic interference.
• Check that ripple voltage on the 5 VDC bus does not exceed 50 mV peak-to-peak to maintain error-free data transmission.
