ABB Bailey INBTM01 Bus Transfer Module

Description

The ABB Bailey INBTM01 is a Bus Transfer Module (BTM) designed for the Infi 90 and Symphony Harmony distributed control systems. Its primary function is to act as a data bridge, allowing information to flow seamlessly between the module bus (local rack) and the expansion bus (remote or adjacent racks).

Specifications

• Model Number: INBTM01
• Compatibility: Infi 90, Symphony Harmony (Harmony Rack).
• Communication Ports: Dual-redundant bus interfaces.
• Bus Speed: Supports standard Infi 90 module bus transmission rates.
• Power Requirements: +5 VDC @ 1.2 Amps (typical) from the backplane.
• Isolation: Built-in galvanic isolation to prevent noise propagation between racks.
• Mounting: Occupies a single slot in the Module Mounting Unit (MMU).

Features

• Seamless Rack Expansion: Extends the reach of the master controller by transferring data to "slave" racks, enabling the system to scale to thousands of I/O points.
• Redundant Pathing: Designed for high-reliability environments; the INBTM01 supports dual-redundant bus architectures to ensure communication remains active if one path fails.
• Low Latency: Optimized for real-time process control, ensuring that signal data from remote I/O reaches the processor with minimal delay.
• Diagnostic LEDs: Front-panel indicators provide immediate feedback on the health of the local bus, expansion bus, and the module itself.
• No Software Configuration: Largely transparent to the system software, acting as a hardware-level bridge that automatically manages data traffic once physical addresses are set via jumpers.
• Ruggedized Design: Built to withstand the harsh electrical and thermal environments typical of power generation and heavy industrial control rooms.
