Weidmuller 8965450000 ACT20X-SAI-HAO-S Current Output Isolator

Description

Designed for hazardous area applications, the Weidmuller 8965450000 (ACT20X-SAI-HAO-S) provides reliable galvanic isolation and signal conditioning for analog current outputs. This high-performance current output isolator safely transmits control signals from safe-area controllers to intrinsically safe (Ex i) actuators, control valves, or I/P converters located in hazardous environments. Featuring an integrated alarm relay, the module monitors critical faults such as line interruptions, signal limit violations, and power supply failures, ensuring maximum process safety and system availability.

The device is fully configurable via standard FDT/DTM software, allowing engineers to customize alarm thresholds and operational parameters to match specific process requirements. Its compact 22.5 mm housing design optimizes cabinet space, making it an ideal choice for high-density control panels in demanding industrial environments.

Features

• Galvanic isolation between input, output, and power supply circuits.
• Intrinsically safe (Ex i) output design for hazardous area field devices.
• Integrated alarm relay for real-time fault signaling and diagnostics.
• FDT/DTM software-based configuration for precise parameterization.
• Fast step response time of 5 ms or less for dynamic control loops.
• Compact DIN-rail mountable housing with screw connection technology.

Applications

• Chemical and petrochemical processing plants.
• Oil and gas extraction, refining, and distribution.
• Water and wastewater treatment facilities.
• Power generation and utility control systems.
• Intrinsic safety isolation for control valves, positioners, and I/P converters.

Technical Specifications

Installation Guidelines

• Mounting: Install the device vertically on a standard TS 35 DIN rail.
• Ventilation: Ensure adequate clearance around the module to facilitate natural convection cooling, especially when mounting multiple units side-by-side.
• Wiring: Use appropriate wire cross-sections for the screw terminals. Keep intrinsically safe (Ex i) field wiring physically separated from non-intrinsically safe power and signal wiring in compliance with local electrical codes.
• Grounding: Ensure the DIN rail is properly grounded to a low-impedance earth ground to maintain signal integrity and safety shielding.
