Weidmuller 8965490000 ACT20X-HUI-SAO-S Universal Measurement and Signal Isolating Converter

Description

Processing temperature and electrical signals from hazardous areas requires specialized, intrinsically safe isolation. The Weidmuller 8965490000 ACT20X-HUI-SAO-S functions as a highly adaptable universal signal isolator and measurement converter, designed to condition, isolate, and convert analog signals from Ex Zone 0, 1, or 2 environments. This module accepts a wide range of inputs including RTDs, thermocouples, resistors, and active/passive current or voltage signals, converting them into standard active or passive current/voltage analog outputs.

Equipped with an integrated alarm relay, the device provides rapid fault signaling in the event of sensor errors or power loss. Configuration is managed via standard FDT/DTM software, allowing precise parameterization for diverse industrial applications. The compact 22.5 mm housing saves valuable DIN rail space while ensuring high galvanic isolation between the input, output, power supply, and relay contacts.

Features

Intrinsically safe input circuit (Ex ia) certified for Zone 0, 1, and 2 applications.
Universal input capabilities supporting RTDs, thermocouples, potentiometers, resistance, and mA/V signals.
Flexible analog output configurable for active or passive current and voltage loops.
Integrated relay output for limit value monitoring and system alarm functions.
Galvanic 4-way isolation between input, output, power supply, and relay contacts.
FDT/DTM software-based configuration for precise calibration and diagnostic monitoring.
Secure screw connection technology for reliable field wiring in high-vibration environments.

Applications

Chemical and petrochemical processing plants.
Oil and gas extraction, refining, and distribution.
Water and wastewater treatment facilities.
Power generation and thermal plant monitoring.
Hazardous area signal conditioning and safety instrumented systems (SIS).
