Product Description

Overview

The HIMA H4135A is a high-integrity safety relay module engineered for integration with HIMA’s HIQuad (H41q/H51q) programmable safety systems. Designed for SIL 3 applications, it provides reliable electrical isolation and safe switching between safety controllers and field actuators, ensuring critical process safety functions are executed under all conditions.

Key Features

High Safety Integrity

  • Certified for SIL 3 according to IEC 61508 and Cat.4 / PL e per IEC 62061

  • Quad-channel design with diverse internal relay architecture to prevent common-cause failures

  • Safe galvanic isolation between input control circuits and output contacts (500 VAC RMS)

Reliable Switching Performance

  • Independently monitored relay channels capable of both NO and NC configurations

  • Hard gold-plated AgNi contacts for long-term durability in low-signal or higher power switching

  • Rapid response with ~8 ms switching time and ~6 ms reset time

  • Rated for over 30 million mechanical cycles and 250,000 electrical cycles at rated load

Installation and Physical Attributes

  • Compact module: 12.5 mm (W) × 100 mm (H) × 100 mm (D)

  • Lightweight: approximately 150 g

  • Standard 35 mm DIN rail mounting; supports horizontal or vertical installation

  • Wiring up to 2.5 mm² (AWG 14) compatible
