Product Overview

The HIMA F 7130A is a dedicated power supply module for the PES H41q safety system. This DC/DC converter takes 24 VDC input and produces stable 5 VDC output. It provides electrical isolation between the input and output voltages. The F 7130A supplies separate power paths for the central device, I/O modules, and HIBUS interface. You get overvoltage protection and current limitation for reliable safety system operation.

Technical Specifications

Input Characteristics

• Input Voltage: 24 VDC with -15% to +20% tolerance.

• Input Ripple: Maximum pp less than 15%.

• Primary Fuse: 5 A gL type.

• Monitoring Supply: Fed separately via pin z16 (NG) for central device monitoring.

Output Characteristics

• Output for Central Device and I/O Modules: 5 VDC at 10 A maximum.

• Output for HIBUS Interface: 5 VDC at 1 A maximum.

• Output Voltage Tolerance: +0.25 V for both outputs.

• Efficiency Rate: 70% or higher under normal load.

• Short-circuit Protection: All outputs are short-circuit proof.

• Overvoltage Protection: Built-in for safe module operation.

• Current Limitation: Prevents damage from overload conditions.

Electrical Isolation

• Isolation Type: DC/DC converter with galvanic isolation.

• Isolation Location: Between input voltage and output voltage.

• Separate Supply Paths: Central device and I/O modules use one path.

• Separate Supply Paths: HIBUS interface uses a second dedicated path.

Physical Characteristics

• Space Requirement: 4 SU (standard units).

• Front Panel Indicators: LEDs for input voltage (L+) status.

• Front Panel Indicators: LEDs for output voltage status.

• LED Behavior: Slight illumination of 5 V CPU/EA LED still indicates proper operation.

Installation Guide

Follow these steps to install the HIMA F 7130A correctly. First, verify your 24 VDC supply falls within -15% to +20% tolerance. Second, install the 5 A gL primary fuse in the input circuit. Third, connect the monitoring supply separately via pin z16 (NG). Fourth, insert the module into a 4 SU wide slot in your H41q rack. Fifth, connect the 5 VDC output to your central device and I/O modules. Sixth, connect the separate 5 VDC output to your HIBUS interface. Finally, check the front panel LEDs to confirm normal operation. A slightly dim 5 V CPU/EA LED still indicates proper function.

Frequently Asked Questions (FAQ)

Q1: What happens if the 5 V CPU/EA LED on the HIMA F 7130A lights only slightly?
A: Slight illumination of this LED still indicates proper module operation. This is normal behavior and does not require replacement. The F 7130A continues to supply full rated power even with a dim LED.

Q2: Can I use the HIMA F 7130A with other PES systems besides H41q?
A: This module is specifically designed for the PES H41q safety system. The 5 VDC outputs match the H41q central device and I/O module requirements. Always verify compatibility before using with other systems.

Q3: What is the purpose of the separate monitoring supply via pin z16?
A: Pin z16 (NG) provides dedicated power for the central device monitoring circuit. This separation ensures the monitoring function remains active even if the main supply has issues. It improves overall safety system reliability.

Q4: How much current can the HIMA F 7130A deliver to the HIBUS interface?
A: The HIBUS output provides 5 VDC at up to 1 A maximum. The central device and I/O output provides 5 VDC at up to 10 A maximum. Both outputs are short-circuit proof and current limited.

Q5: What input protection features does the HIMA F 7130A include?
A: The module includes overvoltage protection and current limitation on the input side. The outputs are short-circuit proof for safe field wiring. An external 5 A gL fuse provides additional primary protection.
