Product Description

Overview

The HIMA Z7138 serves as a critical power interface for the HIQuad and H41q/H51q safety systems. This dual-function module combines power supply filtering and connector capabilities to ensure stable, clean, and protected 24 VDC power distribution across the system subrack. By eliminating electrical noise and protecting against transient voltage events, it safeguards the sensitive safety CPUs and I/O modules.

Engineered for industrial environments, the Z7138 delivers reliable performance under vibration, shock, and extreme temperatures, making it an essential element of SIL 3-rated safety systems.

Key Features

• Filters high-frequency noise and EMI from incoming 24 VDC power

• Protects against overvoltage and accidental reverse polarity

• Distributes power efficiently to the subrack backplane and modules

• Front cable connector with watertight sealing for moisture resistance

• Rugged design to endure vibration, shock, and dust

• Gold-plated contacts for corrosion-free connections

• Wide operating temperature range from -40°C to 85°C

Technical Specifications

Applications

The Z7138 ensures clean and reliable power delivery in safety-critical environments such as chemical plants, oil & gas facilities, and energy production sites. It supports redundant configurations, allowing dual modules to maintain continuous operation if one fails.
