The HIMA F7126 is a versatile module that appears in different contexts across the search results, primarily as a power supply module 🛠️ for safety systems and potentially as other types of modules. Here’s a synthesis of its technical specifications based on the provided search results:

🔧 1. Module Type and Primary Function

• The F7126 is primarily described as a power supply module within HIMA’s safety system architecture, particularly in the H51Q-HRS system used on marine platforms .
• It is also listed as a digital input module in one source , though this might be a misclassification or a different variant, as the majority of sources point to its power supply function.

⚡ 2. Electrical Specifications

• Input and Output: It provides redundant power distribution with features like isolation, overvoltage protection, and current limiting. Outputs are short-circuit protected .
• Voltage Adjustment: The front panel includes test sockets and a potentiometer for adjusting output voltage. In redundant setups, the output voltage difference between modules should be minimal (denoted as “V” in the source, likely a small value) .
• Load Balancing: Designed for load balancing in redundant configurations .

🛡️ 3. Safety and Reliability Features

• High Reliability: Built with quality materials and craftsmanship for stable long-term operation in harsh industrial environments .
• Functional Safety: Part of HIMA’s safety systems, which are TÜV-certified (e.g., AK6/SIL3) . The F7126 itself supports critical safety functions with features like watchdog timers and diagnostic logging .
• Diagnostics: Capable of storing diagnostic information (e.g., up to 500 entries per I/O module) and transmitting these to a DCS . It also logs maintenance activities such as resets, downloads, and mode changes .

🔌 4. Mechanical and Physical Specifications

• Form Factor: Supports both panel and rack mounting .
• Temperature Range: While not explicitly stated for the F7126, HIMA systems often operate in industrial temperature ranges. One related source mentions an operating temperature of -40°C to +85°C for a different module .

🖥️ 5. System Integration

• Compatibility: Integrates with HIMA’s HIMax platform, which supports various redundancy configurations (e.g., dual, quadruple) and allows online hardware and software changes .
• Communication: Although primarily a power module, it exists within systems that support communication protocols (e.g., TSN, safety Ethernet) for data exchange with DCS and other devices .
