ACT20M Expansion
More Analog Functionality in a 6mm Wide Package

ACT20M: The Slim Solution
Space-Saving Signal Converter

Looking for more space in your switch cabinet? The ACT20M series and our ACT20-FEED-IN supply modules offer the ideal space-saving solution.
The ACT20M series combines innovative technology with top functionality in an electronics housing that is just 6 mm wide. The supply device eliminates the need to wire a power supply to the modules, reducing installation time by at least 30%. The ACT20-FEED-IN-PRO-S can supply and monitor up to 120 devices mounted on the CH20 DIN rail bus.
The ACT20M series includes passive isolators, universal measuring transducers, DC isolating amplifiers, and signal splitters, which are capable of reading bipolar input voltages. Temperature transducers and power-supply devices are also available.

• Temperature and Voltage/Current: Suitable for thermocouples, RTDs, and bipolar D.C.
• Power Rail Option Saves Installation Time: No jumpers needed.
• Choice of Isolation/Conversion: Includes low-cost non-isolating models.
• Wide Temperature Input Range: Easy configuration with DIP switches.
• Global Approvals: Available with cULus and Div 2 / Zone 2 approvals.

Analog Signal Conditioners

• Selectable Output Ranges: Configurable outputs for ranges between -20...+20 mA or -10...+10V.
• Accuracy: Improved measurement accuracy down to 0.5% of the full-scale measurement.

Multifaceted: ACT20P-CMT
Flexibility and Accuracy in Diverse Applications

Universal Solution: ACT20P-PRO DCDC

• Configurable range: ±300 VDC or ±100mA input range.
• Integrated Display: Configurations and settings can be made easily via the front display or additional DIP switches.
• Flexible Power Inputs: Models with input power supply ranges from 24 to 230Vac/dc, or only with 24Vdc.
• Complete Line Detection: Easier troubleshooting with short circuit and wire break detection built-in.
• Precise Data Recording: Measurement data is converted and transmitted with an accuracy of 0.05%.

Secure Isolation of Signals from Hazardous Areas
Intrinsically Safe ACT20X Ex-Signal Converters

For applications where signals need to be routed to or from hazardous areas, our ACT20X intrinsically safe signal isolating converters meet the strict standards of the process industry. They process signals from a wide range of Ex-zones (Zones 0, 1, 2) for control purposes.

• Universal Usage: On the input side, the converter can process HART® input signals, or DC, RTD, thermocouple, or NAMUR signals from the Ex-zone. On the output side, ACT20X controls field devices with analogue or digital signals.
• High Insulation & Accuracy: All ACT20X products are characterized by high insulation, accuracy, and temperature stability.
• Space-Efficient: The 2-channel versions (22.5 mm wide) are available with either transistor or relay output.
• Reduced Installation Costs: Due to the highly integrated design, reducing space and overall cost.
• SIL Approval: ACT20X also offers SIL approval for safety functions like monitoring actuators or temperature/pressure.

Configuration via WI Manager
All modules can be quickly and conveniently configured using manufacturer-independent FDT/DTM software.

Intelligent Connection System
Pluggable, coded, with a release lever, simplifying maintenance and enabling disconnection without damaging cables.

• Worldwide Application: Fulfills strict process industry standards and is applicable worldwide with international and local approvals like ATEX, IECEX, CULUS, FM, GOST, and DNV.

Alarm Function
Integrated alarm function for cable or sensor errors. In case of failure, a diagnostic signal is sent to the control system, eliminating laborious troubleshooting.

• Robust Design: Wide ambient temperature range from -20°C to +60°C.

SIL Certification
Available for safety functions, including switching aggregates on/off, monitoring actuators, or temperature/pressure.
