Weidmuller 8965340000 ACT20X-HDI-SDO-RNO-S Isolating Switch Amplifier

Description

Processing digital signals from hazardous zones requires robust galvanic isolation and signal conditioning. The Weidmuller 8965340000 functions as an intrinsically safe isolating switch amplifier designed to interface NAMUR sensors or mechanical contacts located in Ex zones 0, 1, and 2 with safe-area controllers. This dual-channel module provides reliable signal transmission while ensuring complete electrical isolation between the input, output, and power supply circuits. Configurable via FDT/DTM software, the device allows for precise parameterization of line monitoring (wire break and short-circuit detection) and output behavior.

Features

Dual-channel signal transmission for space-saving DIN rail installation.
Intrinsically safe input circuits compatible with NAMUR sensors (EN 60947-5-6) and dry contacts.
Relay outputs (normally open) for switching AC/DC loads.
Comprehensive line fault detection (LFD) for identifying short circuits or cable breaks.
Galvanic 3-way isolation between input, output, and power supply.
FDT/DTM software configuration for flexible parameter adjustments.

Applications

Chemical and petrochemical processing plants
Oil and gas extraction and refining facilities
Wastewater treatment and hazardous material storage
Power generation and distribution systems
