HIMA B9302 997009302 I/O Rack (H41q/H51q)
Basic Information
HIMA B9302 997009302 is a 4U‑height 19‑inch I/O expansion rack kit compatible with H41q/H51qsafety control systems, part number 997009302. The complete set includes FK1406 rack body, F7553 coupling module and BV7032 flat bus cable. It is used to expand I/O points of HIMA safety PLC and serves as the I/O sub‑carrier for H51q distributed systems. A single B9302 997009302 can accommodate up to 16 I/O modules. Up to 16 sets of such racks can be connected to the central main rack to build large‑scale safety instrumented systems. B9302 997009302 relies on a dedicated I/O bus for deterministic communication between the central rack and distributed I/O modules, and is widely applied in process‑industry safety interlock scenarios.

Frequently Asked Questions
Q: Can B9302 997009302 be used directly as a central main rack?
A: No. B9302 997009302 is an I/O expansion sub‑rack. It only carries I/O modules and cannot accommodate CPU or power‑supply units. It must work together with H41q/H51q central rack kit.
Q: Is there a mandatory order for module placement in slots 1‑16 of B9302 rack?
A: Digital‑input and analog modules can be freely placed in slots 1‑16. A maximum of 8 pcs F3330 output modules can be installed per B9302 rack due to rack power‑supply budget constraints.
Q: How many B9302 997009302 racks can one H51q system support?
A: H51q system supports up to 16 units of B9302‑type I/O sub‑racks, and total bus cable length shall not exceed 30 meters.
Q: What are the differences between B9302‑0.5, B9302‑1 and B9302‑X?
A: The rack body hardware is identical for all three versions; differences lie only in BV7032 flat bus cable. ‑0.5 stands for 0.5 m, ‑1 for 1 m, ‑X for customer‑specified custom length. Part number 997009302 corresponds to complete B9302 kit.
Q: Does B9302 997009302 support H41q compact system?
A: H41q compact system comes with built‑in I/O slots. B9302 is mainly intended for H51q distributed architecture. It is hardware‑compatible for H41q expansion, but total system I/O quantity limits need to be evaluated.
Q: Does B9302 997009302 kit include F7133 power‑distribution module?
A: Standard B9302 kit does not include F7133. F7133 is an optional accessory to be ordered separately. Standard kit includes FK1406 rack, F7553 coupling module and BV7032 bus cable.
Q: If B9302 rack fails and only FK1406 rack housing is replaced, can original F7553 still be reused?
A: F7553 coupling module can be removed and reused. Re‑insert it into Slot 17 after replacing rack housing and confirm proper bus‑cable connection.
Q: Can B9302 997009302 be used for new‑generation HIMax systems?
A: No. B9302 997009302 belongs exclusively to legacy H41q/H51q series; its hardware bus is incompatible with HIMax controllers.
Notes
- B9302 997009302 is for cabinet‑internal use only. It cannot be directly deployed in hazardous explosive areas; on‑site explosion‑proof application requires additional flame‑proof enclosures.
- Total bus length must be strictly kept within 30 meters; exceeding this limit will cause unstable bus communication.
- Slot 17 must be fitted with F7553 coupling module; sub‑rack cannot communicate normally if this slot is vacant.
- Rack ground terminals must be reliably connected to cabinet protective earth to guarantee EMC anti‑interference performance.
- Configuration shall be completed via ELOP II software; slot addresses in software must match actual physical module arrangement after hardware installation.
- Quantity of output modules shall not exceed per‑rack power‑supply limit, otherwise loop power‑supply insufficiency faults will occur.
