ABB GHR4130000V0 BBC Brown Boveri Procontic Relay Module

Product Overview

The GHR4130000V0 is a legacy relay module originating from the BBC Brown Boveri era, now maintained under the ABB industrial heritage portfolio. This module belongs to the Procontic range, one of the earliest and most reliable programmable logic control (PLC) families developed for demanding industrial automation and protection environments.

Specifically engineered for dependable switching and interlocking operations, the GHR4130000V0 plays a critical role in legacy control systems deployed in power distribution facilities and heavy manufacturing plants. Although classified as obsolete, this module remains an essential spare part for maintaining operational continuity in existing Procontic installations without requiring a full system upgrade.

Technical Configuration

The GHR4130000V0 is built according to the deterministic hardware standards established by BBC Brown Boveri engineering:

• Procontic Architecture: Designed for fast logic execution and stable I/O handling within the Procontic PLC system framework.
• Relay Logic: Utilizes high-quality switching components to provide reliable galvanic isolation between control logic and field equipment.
• Protection Functions: Commonly used in command and signaling circuits to support hardware-level safety interlocking.
• Compact Form Factor: Dimensions of 15 × 13 × 5 cm allow installation within standard Procontic racks and industrial cabinets.

Technical FAQs

How do I replace a GHR4130000V0 in an active Procontic system?

Since this module is obsolete, replacements must be sourced from certified legacy inventory. Before installation, isolate system power and verify that terminal labeling and voltage ratings match the original unit to prevent backplane damage.

What are the common failure modes for this relay module?

Typical failures include contact welding caused by excessive current and coil fatigue in high-cycle applications. When these symptoms appear, replacement with verified stock is usually the safest corrective action.

Is there a direct modern replacement for the Procontic GHR series?

There is no direct plug-and-play equivalent. System modernization typically involves migration to newer PLC platforms such as AC500 or AC800M, which requires redesign of wiring and control logic.

Engineering & Installation Guide

Contact Protection:
Use external surge suppression devices when controlling inductive loads. RC snubbers are recommended for AC circuits, while flyback diodes are required for DC loads.

Cleaning and Inspection:
Inspect edge connectors for oxidation before installation. Use a non-residue electronic contact cleaner and avoid abrasive materials that may damage plated contacts.

Mounting Torque:
If screw terminals are used, maintain tightening torque within the recommended range of approximately 0.5 to 0.8 Nm to prevent housing damage.

Thermal Consideration:
Ensure cabinet cooling fans operate correctly. Legacy electronic components are more sensitive to elevated temperatures and may experience instability under thermal stress.
