Power Distribution and Protection
The F7130A converts the 24 VDC input into a regulated 5 VDC supply for the central processing device and I/O modules. A separate 5 VDC output supplies the HIBUS interface. These outputs have individual current ratings, allowing the module to distribute power to the designated system sections.
The converter provides electrical isolation between its input and output. In addition, overvoltage protection and current limitation help protect the connected circuitry. The outputs are short-circuit proof, while the primary circuit uses a specified 5 A gL fuse.
Status Indication and Monitoring
LED indicators on the front plate show the presence of the input voltage (L+) and the output voltages. The 5 V CPU/EA indicator may illuminate only faintly while the module continues to operate correctly; therefore, a dim indicator alone does not necessarily indicate a power supply fault.
The power supply for monitoring the central device receives a separate feed through pin z16 (NG). This connection is distinct from the main power distribution paths and should be considered when checking the module’s wiring and supply arrangement.
Frequently Asked Questions
Q: What input voltage does the HIMA F7130A require?
A: The module operates from a nominal 24 VDC input with a tolerance of -15% to +20%. The specified input ripple is less than 15%.
Q: What are the 5 VDC output ratings?
A: The central device and I/O modules receive 5 VDC at up to 10 A, while the HIBUS interface receives 5 VDC at up to 1 A. Both outputs have a voltage tolerance of +/- 0.25 V.
Q: Is the HIMA F7130A still manufactured?
A: The supplied product information identifies the F7130A as discontinued by the manufacturer. When sourcing a replacement, verify the required power ratings, connector arrangement, monitoring connections, and system compatibility before selecting another module.
