Core functions

Convert 24VDC to isolated 5VDC, providing power for the CPU, I/O backplane and HIBUS interface of the H41q/HIQuad system

Electrical isolation of input and output, blocking interference

Integrated overvoltage, undervoltage, overcurrent, short circuit and overheating protection, self-protection in case of faults

Independent power supply circuit design, separate power supply for CPU/I/O and HIBUS interface

Panel LED indicators, showing input voltage (L+) and output status

Support for hot swapping, allowing module replacement online

Caution for use

Reserve space for heat dissipation, away from strong interference equipment such as frequency converters and contactors

24V input uses an independent regulated power supply, not connected to high-power loads in the same circuit

The cabinet is reliably grounded, with a grounding resistance of ≤ 4Ω, single-ended grounding of the shielding wire

Ensure consistent output voltage of the two modules during redundant parallel operation to avoid internal circulation

Regularly check terminal fastening, no oxidation, and no condensation

Faults can be directly replaced with the same model without modifying wiring and programs
