Product Description

Description

Intrinsically safe signal transmission in hazardous industrial environments is managed efficiently by the 8965390000 isolating switch amplifier. This dual-channel module processes digital signals from Ex Zone 0 areas, providing reliable galvanic isolation and signal conditioning for NAMUR sensors and mechanical contacts. By isolating the input and output circuits, the device ensures safe operation of control systems in the safe zone.

Engineered with advanced diagnostics, the ACT20X-2HDI-2SDO-S supports comprehensive alarm monitoring to identify fault conditions instantly. The module is configured via standardized FDT/DTM software, allowing precise parameter adjustment and simple integration into modern distributed control systems (DCS) and PLC architectures.

Features

  • Dual-channel digital input (2HDI) and digital output (2SDO) configuration.
  • Intrinsically safe isolation barrier designed for Zone 0, 1, and 2 applications.
  • Integrated diagnostic alarms for line interruption, input short circuits, supply voltage loss, and internal device errors.
  • FDT/DTM software-based configuration for flexible parameter setup.
  • Compact 22.5 mm DIN-rail housing to optimize cabinet space.
  • Robust screw connection terminals for secure wiring in high-vibration environments.

Applications

  • Oil and gas extraction and refining facilities.
  • Chemical and petrochemical processing plants.
  • Wastewater treatment plants with hazardous gas environments.
  • Power generation and fuel storage monitoring.

Installation Guidelines

  • Mount the device vertically or horizontally on a standard TS 35 DIN rail.
  • Maintain a minimum clearance around the module to ensure proper natural convection cooling.
  • Ensure strict physical separation between intrinsically safe (Ex) and non-intrinsically safe wiring paths.
  • Verify that the DIN rail is properly grounded to the functional earth of the control cabinet.
