Processing temperature signals from hazardous areas requires high-integrity isolation, which is precisely what the Weidmuller ACT20X-HTI-SAO-S (Article Number 8965470000) delivers. This intrinsically safe temperature transducer converts RTD and thermocouple inputs into a standard isolated analog current signal, ensuring safe and accurate data transmission to the control system. Designed for DIN-rail mounting, it integrates seamlessly into modern process automation architectures.

Key Features

Intrinsically safe input designed for Zone 0 / Division 1 hazardous area deployments.
FDT/DTM software-based configuration for precise calibration and parameterization.
Integrated alarm relay output for line interruption, short circuit, and device errors.
High galvanic isolation between input, output, and power supply circuits.
Compact 22.5 mm housing width to maximize control cabinet density.

Industrial Applications

Chemical and petrochemical processing plants.
Oil and gas extraction and refining facilities.
Power generation thermal monitoring.
Water and wastewater treatment systems.

Empirical Engineering Insights

Alternative Models & Compatibility

The ACT20X-HTI-SAO-S is part of Weidmuller's specialized intrinsically safe signal converter family. It requires the WI-Manager software (FDT frame) and the specific ACT20X DTM driver package for configuration. Ensure your USB interface cable (such as the Weidmuller CBX200) is compatible before attempting setup.

Application Pitfalls & Engineering Notes

When mounting multiple ACT20X modules side-by-side on a DIN rail, ensure adequate cabinet ventilation. Although the power consumption is low (<= 0.8 W), high ambient temperatures exceeding 60 degC can degrade the internal optocouplers over long-term operation. Always verify that the Ex-protection parameters (Uo, Io, Po) match the connected field sensor's entity parameters.

Commissioning & Wiring Tips

For thermocouple inputs, ensure the cold junction compensation (CJC) is correctly configured in the DTM software. If using RTDs, 3-wire or 4-wire configurations are highly recommended over 2-wire setups to eliminate lead resistance errors. Shielded cabling must be grounded only at the designated safe-area ground point to prevent ground loops.

Installation Guidelines

CRITICAL WARNING: De-energize all power sources before mounting, wiring, or configuring the device. Ensure the installation complies with all local and international intrinsic safety regulations (Ex-protection). Do not connect non-intrinsically safe signals to the blue Ex-input terminals.

Mount the device vertically on a standard TS 35 DIN rail.

Connect the temperature sensor to the blue Ex-input terminals (41-44) following the sensor-specific wiring diagram.

Wire the analog output (11-12), power supply (13-14), and alarm relay (51-52) to the safe-area terminals.

Apply power and connect via the front-panel interface to configure sensor type and scaling parameters using FDT/DTM software.

How do I configure the ACT20X-HTI-SAO-S transducer?

Configuration is performed using standard FDT/DTM software (such as Weidmuller WI-Manager) via a compatible USB interface cable connected to the front-panel port.

What types of sensors can be connected to this module?

It supports standard RTDs (such as PT100, PT1000) and various thermocouple types (J, K, T, E, R, S, B, N), as well as direct resistance inputs.

Is this module suitable for installation in hazardous areas?

Yes, the module features intrinsically safe inputs designed for connection to sensors located in Zone 0 / Division 1 hazardous areas, while the module itself is installed in the safe area.

What happens if there is a sensor line break or short circuit?

The integrated alarm relay output triggers immediately, and the analog output signal transitions to a pre-configured fail-safe state to protect downstream processes.
