Description

Designed for intrinsic safety applications, the **Weidmuller 8965380000** functions as a highly reliable 2-channel **isolating switch amplifier**. This device transmits digital signals from hazardous areas (Zone 0, 1, 2) to safe areas, providing complete galvanic isolation between the input, output, and power supply. It is specifically engineered to interface with NAMUR sensors and mechanical contacts, converting their states into digital relay outputs.

The **ACT20X-2HDI-2SDO-RNC-S** features integrated line fault detection (LFD) capable of identifying line interruptions or short circuits at the input. Diagnostic status and device errors are signaled via an integrated alarm contact, ensuring high system availability and simplified troubleshooting. Configuration is easily performed using standard FDT/DTM software, allowing for precise adjustment of input types, output behavior, and diagnostic parameters.

Features

  • Dual-channel design for space-saving installation on standard DIN rails.
  • Complete 3-way galvanic isolation between input, output, and power supply.
  • Supports both NAMUR sensors and mechanical contact inputs.
  • Integrated line fault detection (LFD) for short-circuit and wire-break monitoring.
  • Dedicated alarm relay output for system diagnostics and error reporting.
  • Simple configuration and parameterization via FDT/DTM software.
  • Secure screw connection terminals for reliable field wiring.

Applications

  • Chemical and petrochemical processing plants.
  • Oil and gas extraction, refining, and distribution.
  • Water and wastewater treatment facilities.
  • Hazardous area signal isolation and safety-instrumented systems.

Installation Guidelines

  • Mounting: Install vertically on a standard TS 35 DIN rail. Ensure the module is securely locked into place.
  • Wiring Separation: Maintain strict physical separation (at least 50 mm) between intrinsically safe (blue terminals) and non-intrinsically safe wiring to comply with safety standards.
  • Grounding: Ensure the DIN rail is connected to a low-impedance functional earth ground.
  • Ventilation: Provide sufficient clearance above and below the device to allow natural convection cooling and prevent heat accumulation.

Compliance and Certifications

  • CE
  • ATEX
  • IECEx
  • cULus
