Operating as an intrinsically safe solenoid driver, the Weidmuller ACT20X-SDI-HDO-H-S controls valve systems, acoustic alarms, and indicators located in hazardous areas. This high-performance module provides galvanic isolation between the control system and the field devices, ensuring reliable signal transmission and robust explosion protection in demanding process environments.

Key Features

Intrinsically safe output (Ex ia IIC) designed for direct deployment in hazardous areas.
Integrated alarm relay output for immediate signaling of power loss or internal device errors.
FDT/DTM software-based configuration for precise parameterization and diagnostic monitoring.
Compact 22.5 mm DIN-rail housing to optimize space within electrical control panels.
Secure screw connection technology to guarantee long-term, vibration-resistant wiring.

Industrial Applications

Chemical and petrochemical processing plants with explosive atmospheres (Zone 0, 1, and 2).
Oil and gas extraction, refining, and distribution facilities.
Pneumatic and hydraulic solenoid valve control in hazardous process loops.
Industrial signaling, beacon control, and acoustic alarm integration.

Empirical Engineering Insights

Alternative Models & Compatibility

The ACT20X-SDI-HDO-H-S is fully compatible with standard FDT/DTM frame applications such as Weidmuller WI-Manager. When replacing legacy ACT20X models, ensure that the configuration profile is exported and reloaded using the CBX200 USB interface cable to preserve specific safety loop parameters.

Application Pitfalls & Engineering Notes

When mounting multiple ACT20X modules side-by-side on a DIN rail, ensure cabinet ventilation maintains ambient temperatures below 60 degC. High-density packing without adequate airflow can lead to localized thermal stress. Always verify that the Ex-i output parameters (Uo, Io, Po) strictly match the electrical characteristics of the connected solenoid valve to maintain safety loop integrity.

Commissioning & Wiring Tips

Perform offline configuration via the front-panel port before mounting the unit onto the DIN rail. Ensure that intrinsically safe field wiring (hazardous area) is physically separated from non-intrinsically safe wiring (safe area) by a minimum distance of 50 mm, or utilize physical partitions in compliance with IEC/EN 60079-14 standards.

Installation Guidelines

CRITICAL WARNING:

Isolate all power sources before mounting, wiring, or configuring the device. Failure to de-energize the system prior to installation in hazardous areas can result in electrical arcing, leading to severe equipment damage, explosion, or personal injury.

1 Mount the module vertically onto a standard TS 35 DIN rail, ensuring secure mechanical latching.

2 Connect the intrinsically safe field device wiring to the Ex-designated terminals (Terminals 41 and 42).

3 Wire the control input, alarm relay, and the 24 V DC power supply to the safe-area terminals.

4 Connect the CBX200 USB cable to configure the alarm thresholds and operational parameters via FDT/DTM software.

#Valve Control Modules #Weidmuller ACT20X Series

How is the ACT20X-SDI-HDO-H-S module configured?

Configuration is performed using standard FDT/DTM software via a CBX200 USB interface cable connected to the front-panel port.

What is the purpose of the integrated alarm relay?

The alarm relay provides a normally closed (NC) contact that opens to signal a loss of supply voltage or an internal device error.

Can this module drive solenoid valves located in Zone 0?

Yes, the output circuit is rated intrinsically safe (Ex ia IIC), allowing direct connection to solenoid valves and indicators in Zone 0, 1, or 2.

What are the maximum switching limits for the alarm contact?

The alarm relay contact supports up to 125 V AC at 0.5 A or 110 V DC at 0.3 A.
