The HIMA 80105 (order number 984080105) is a high-reliability power supply module specifically designed for use in HIMatrix safety systems. It accepts a nominal 24 VDC input from an external industrial power source and provides the regulated voltages required by the CPU, I/O modules, and communication interfaces within the HIMatrix controller. Certified for safety applications up to SIL 3 (IEC 61508), the 80105 ensures that critical safety functions receive clean and stable power, even under fault conditions. Its compact design integrates seamlessly into the HIMatrix chassis, and its comprehensive diagnostics allow for continuous monitoring of power quality.
SIL3 Certified: Suitable for high-integrity safety functions requiring the highest risk reduction.
Wide Input Range: Accepts 24 VDC nominal (18–32 VDC) with reverse polarity protection.
Integrated Diagnostics: Front-panel LED indicators for power OK and fault; remote status via relay contact.
Short-Circuit Protection: Output protected against overloads and short circuits; automatic recovery.
Redundancy Ready: Can be used in 1+1 redundant configurations with external decoupling.
Hot-Swappable: In redundant mode, a faulty module can be replaced without system shutdown.
Input Voltage: 24 VDC nominal (18–32 VDC)
Input Current: 2.0 A typical (depending on load)
Output Power: 25 W (typical) to backplane
Efficiency: > 85%
Isolation: 500 VAC between input and output
Diagnostics: Relay contact rating 30 VDC / 1 A
Operating Temperature: -20°C to +60°C
Certifications: TÜV Rheinland (SIL3), CE, UL, ATEX (Zone 2)

The 80105 is used in HIMatrix safety systems deployed in process industries such as oil & gas, chemical, petrochemical, and power generation. Typical applications include emergency shutdown (ESD), fire and gas detection (F&G), burner management (BMS), and turbine control. In redundant configurations, it ensures that a single power supply failure does not interrupt safety functions, meeting the high availability requirements of SIL 3 applications.
The module plugs into the HIMatrix chassis and is automatically recognized by the safety CPU. The diagnostic relay can be wired to a digital input module to report power status to the safety controller. The front-panel LEDs provide immediate visual feedback: green for normal operation, red for fault. In redundant setups, both modules share the load; if one fails, the other continues to supply full power without interruption.
Designed for harsh industrial environments, the 80105 meets IEC 61000-4 immunity standards and is tested for vibration and shock. Its operating temperature range of -20°C to +60°C covers most process plant conditions. The module is RoHS compliant and carries CE and UL marks for global acceptance.
With its robust design and safety certifications, the HIMA 80105 (984080105) power supply module ensures reliable power delivery for critical safety systems, contributing to overall plant safety and availability.
