“WOW” Our new Weidmüller ACT20C gateway provides greater transparency and preventive monitoring for equipment and processes

“With our new ACT20C gateway and communication-enabled signal converters you can for the first time obtain extensive information directly from the signal conversion level.”

The Weidmüller ACT20C gateway provides greater transparency as well as preventive monitoring of systems and processes. The “smart software configuration” of modules is based on the FDT and FDT2 standards.

The new ACT20C gateway supplies precise diagnostics and status information on devices used in various areas of automation, while performing preventive monitoring of systems and processes. In this way, the ACT20C gateway plays a big part in optimising the control of processes. With our ACT20C gateway and communication-enabled signal converters, it is now possible to obtain comprehensive information directly from the signal conversion level – regardless of the automation solution selected. An Ethernet interface provides easy access to the desired information: the data acquired by the ACT20C gateway is processed by Modbus TCP or can be displayed directly in an FDT frame application. The “smart software configuration” of the modules is based on the FDT and FDT2 standards.

The ACT20C gateways have a flexible design, which helps to simplify process optimisation. Depending on the communication infrastructure in use, data can be made available throughout the network or relayed to a SCADA or maintenance system. The data can be used from any location over the Internet via an Industrial Ethernet router. The Ethernet interface transmits important diagnostics, which, for example, supports the rapid correction of system errors.

The station design with “Plug & Produce” and “hot swapping” makes installation and maintenance work faster and thus more economical.

The current status of equipment, functions and ambient conditions are monitored continuously via Ethernet, which means that users have a clear overview of all process parameters with the new ACT20C gateways. In addition, station management with “Plug & Produce” and “hot swapping” speeds up installation and maintenance, thereby increasing efficiency. The comprehensively designed diagnostics concept supports fast and precise root cause analysis in line with Namur recommendations NE107 and NE43.

An ACT20C-GTW-100-MTCP-S gateway provides access to all data from the devices connected to an ACT20C station. An RJ45 port with Ethernet TCP/IP and 10/100BaseT (X) is used for this purpose. There is also a jack plug for local communication via a CBX200 USB interface. The gateway receives data via the CH20M rail bus from multiple ACT20C (ACT20C-CMT-x) communication-enabled current measuring transducers. In addition to dynamic addressing via DHCP, manual settings based on the FDT and FDT2 standards are also possible. This simplifies the setting of parameters as well as documentation and data backups. Monitoring and configuration take place on the ACT20C gateway station.

The status of devices, environmental conditions and functions are continuously monitored via Industrial Ethernet.

The communication-enabled ACT20C CMT current measuring transducer can be combined with the gateway to measure and monitor AC/DC current. The new current transducer uses the RMS method (True RMS) to capture the real power consumption of a connected load for DC and AC current – even with distorted waveforms. Information about the connected load’s operating behaviour is also determined during this process. ACT20C current measuring transducers measure current very accurately (≤ 0.5% FSR) and supply additional status information via Ethernet.

The input and output ranges of the ACT20C are easy to adjust. With an input measurement range of 0…5/10 A AC (RMS) or DC and an input frequency of AC 15…700 Hz, an output voltage of 0…5 V, 0…10 V, -5…+5 V, -10…+10 V and an output current of 0…20 mA, 4…20 mA, -20…+20 mA, the current measuring transducer offers multiple options for individual settings. The transducer has a relay output for limit value alarms with switching threshold, delay and hysteresis. Multiple threshold monitoring facilitates the precise definition of a range of alarm situations with main and secondary alarms. The alarm delay time can be configured at any position in the range from 0 to 180 seconds. Galvanic four-way isolation and an impulse withstand voltage of 6.4 kV pursuant to IEC 61010-2-201 guarantee a high level of process reliability.

Two variants are available: ACT20C-CMT-10-AO-RC-S with an input measurement range of 0…5/10 A and ACT20C-CMT-60-AO-RC-S with an input measurement range 0…40/50/60 A. The ACT20C-LBT-10 bus termination terminal electrically isolates the CH20M DIN rail bus of an ACT20C station. It also acts as a mechanical end bracket.
