F60 PS 01 | HIMA HIMatrix | F60PS01 Power Supply Module

Product Overview

The HIMA F60 PS 01 functions as the primary power conditioning unit for the HIMatrix F60 modular safety system. It converts external 24 VDC plant power into regulated internal voltages for the central CPU and up to 6 communication or I/O modules. The module sits in Slot 1 of the F60 GEH 01 subrack to ensure stable, noise-filtered energy delivery for SIL 3 safety calculations.

Technical Specifications

• Module Type: System power supply module

• Input Voltage: 24 VDC (-15% to +20%)

• Output Voltages: 5 VDC and 24 VDC internal system bus rails

• Safety Certification: Up to SIL 3 (IEC 61508) and PL e (EN ISO 13849-1)

• Fuse Protection: Integrated 10 A slow-blow fuse on the input side

• Power Dissipation: Less than 15 W at full system load

• Operating Temperature: 0°C to +60°C

Engineering Advantages

• Absorb Voltage Fluctuations: The module tolerates standard industrial voltage drops and spikes without dropping its internal output. It prevents nuisance safety CPU resets during heavy field motor startups.

• Shield Sensitive Logic: Integrated electromagnetic compatibility (EMC) filters block high-frequency noise from reaching the CPU and I/O modules. It stabilizes safety calculations in heavy turbine halls and chemical refineries.

• Overcome Thermal Fatigue: The module transfers heat efficiently to the F60 GEH 01 subrack ventilation path. It runs cool at full load to double the mean time between failures (MTBF).

• Diagnose Supply Faults Fast: Bright front-panel LED indicators display input power status and internal rail health. Technicians isolate utility supply faults from internal hardware faults in seconds.

FAQs

• Question: Can I hot-swap the F60 PS 01 module while the safety system is running?

• Answer: You must shut down the system before removing the power supply module. Pulling the power supply module under load de-energizes the system backplane and triggers a safe state shutdown.

• Question: Does the module contain internal protection against reverse polarity?

• Answer: Yes. The F60 PS 01 incorporates reverse polarity diodes and overvoltage crowbar circuits to prevent internal trace burnouts during wiring accidents.

• Question: How does the system react if the input voltage drops below 18 VDC?

• Answer: The module signals an undervoltage fault to the CPU via the backplane. The CPU then drives all field I/O to their configured safe state before the internal capacitors drain completely.
