Phoenix Contact IBS ST ME 24-BK-T – Inline Bus Terminal Module | INTERBUS Platform
Engineering Background: The INTERBUS (IBS) inline system from Phoenix Contact is a proven fieldbus architecture widely deployed in discrete manufacturing, process automation, and machine-building applications across Europe and Asia-Pacific. The IBS ST ME 24-BK-T serves as a critical bus terminal node within the inline station, providing the electrical and logical interface between the INTERBUS remote bus and the local I/O modules.
Product Positioning: Part number 2754367 is the OEM-designated inline bus terminal module for 24 VDC INTERBUS stations. It is the mandatory head-of-station component that manages bus communication, power distribution, and diagnostic signaling for all downstream inline I/O modules. Procurement engineers specifying INTERBUS expansions or executing like-for-like replacements will find this module essential for maintaining system continuity without re-engineering the station architecture.

System Architecture & Signal Flow
The IBS ST ME 24-BK-T occupies the head position of an INTERBUS inline station. The remote bus (RS-485, 9-pin D-Sub) connects upstream to the INTERBUS master controller (e.g., Phoenix Contact IBS SYS or third-party INTERBUS master cards). The module decodes the INTERBUS frame, extracts local process data, and distributes it across the inline local bus to downstream I/O modules via the proprietary inline connector. Power (24 V DC) is fed through the terminal’s power connector and distributed to the logic rail of all connected inline modules. The -T suffix denotes the terminal block variant, providing screw-clamp field wiring connections directly on the bus terminal body.

Technical FAQ
Q: Is the IBS ST ME 24-BK-T compatible with all Phoenix Contact INTERBUS masters?
A: Yes. It is compatible with all Phoenix Contact INTERBUS master controllers (IBS SYS series, IBS PCI SC/I-T, etc.) and third-party INTERBUS masters conforming to the IEC 61158 / EN 50254 standard.
Q: Can this module be used with non-Phoenix Contact inline I/O modules?
A: No. The inline local bus uses a proprietary Phoenix Contact connector and protocol. Only Phoenix Contact inline I/O modules are compatible downstream.
Q: What does the -T suffix indicate?
A: The -T suffix designates the terminal block (screw-clamp) field wiring variant, as opposed to spring-cage or push-in connection variants.
Q: Is firmware update required after replacement?
A: No firmware update is required. The IBS ST ME 24-BK-T is a hardware module; configuration is managed by the INTERBUS master controller, not the terminal module itself.
Q: Do you provide a Certificate of Conformance (CoC)?
A: Yes, a CoC is available upon request for orders of 5 units or more. Contact [email protected].
