HIMA 6060024 H51q Series Safety CPU Module

The HIMA 6060024, also cataloged as the 6060024 Safety CPU Module, operates as a dedicated hardware component for safety-related logical execution within H51q-MS, HS, and HRS safety-critical programmable electronic systems.

Hardware Specifications

Safety Integrity & Fail-Safe Architecture

• SIL 3 and Category 4 Certification: The internal structural architecture and diagnostic routines of the 32-bit ARM9 processor are certified to meet IEC 61508 SIL 3 and EN ISO 13849-1 Category 4 performance standards, permitting execution in high-demand safety-instrumented systems.
• Fail-Safe State Execution: Upon detection of a critical watchdog timeout, memory corruption, or operating system exception, the module immediately enters the defined fail-safe de-energized state, shutting down external logical channel drives within the configured safety time limit.
• Triple Modular Redundancy (TMR) Interface: The module supports native synchronization protocols over the H51q system backplane, enabling integration into redundant 2oo3 (two-out-of-three) voting matrix configurations to isolate field signal faults.
• Galvanic Port Isolation: Onboard communication controllers for the RS-485 and Ethernet interfaces incorporate structural galvanic isolation barriers to block common-mode electrical surges from penetrating the primary micro-processing core.

Frequently Asked Questions

Q: What is the expected physical service life and replacement cycle of the built-in backup battery?

A: Under standard operating temperatures (25 deg C), the internal backup lithium cell has an operational lifespan of 5 years. A dedicated low-voltage diagnostic warning is broadcast on the backplane bus when the cell potential falls below 2.8 VDC, signaling the requirement for online replacement without loss of active volatile memory.

Q: Can the BS41q/51q operating system firmware be updated while the CPU is executing process logic?

A: No. Firmware flash updates to version BS41q/51q V7.0-8 (05.31) require the safety controller to be completely offline, with the controlled process set to an external safe shutdown state. Updating during active safety loop operations is physically blocked by the hardware key switch locks.

Field Installation Guidelines

Ensure the rack backplane power supply is completely de-energized before inserting or extracting the module to prevent electrical damage to the gold-plated connector pins. The unit must be mounted vertically inside an IP54 or higher rated industrial enclosure to avoid environmental particulate accumulation. Maintain a minimum clearance of 50 mm above and below the module rack assembly to promote natural convective heat dissipation and prevent local temperatures from exceeding the 60 deg C operating limit. All RS-485 and Ethernet communication cables must utilize double-shielded, twisted-pair cabling, with the shield drain wire terminated directly to the low-impedance master ground busbar at the cabinet entry point.
