Expansion modules and accessories for 7KM PAC measuring devices

Expansion modules are used as communication interfaces and for expanding the digital bs/outputs for 7KM PAC measuring devices.

The expansion modules are plugged in at the back of the measuring device. The device identifies the module automatically and presents the relevant beters for this module for selection in the beterization menu.

The following expansion modules are available:

• Expansion module I(N), I(Diff), analog
• 7KM PAC Switched Ethernet PROFINET expansion module
• 7KM PAC PROFIBUS DP expansion module
• 7KM PAC RS 485 expansion module
• 7KM PAC 4DI/2DO expansion module

Expansion module I(N), I(Diff), analog

The 7KM PAC I(N), I(Diff), Analog expansion module offers the following perbance features for the 7KM PAC3200 and 7KM PAC4200 measuring devices:

• N-conductor measurement (IN) Class 1 in accordance with IEC 61557-12
• Residual current measurement (IDiff).
• 2 analog bs for residual current (IDiff) temperature, flow, and pressure measurement, for example
• Continuous monitoring to determine a gradual increase in leakage currents and thus a possibility of reducing costs by preventing disconnection in the case of a BGV A3 test (with summation current transbers TYPE A or TYPE B measurement)
• They provide an expansion option for existing devices and systems at any time.

Connection for 3VA molded case circuit breaker

The following expansion modules can also be mounted on the front of the COM800/COM100 breaker data servers of the 3VA molded case circuit breaker:

• 7KM PAC Switched Ethernet PROFINET and
• 7KM PAC PROFIBUS DP

7KM PAC Switched Ethernet PROFINET expansion module

The 7KM PAC Switched Ethernet PROFINET expansion module is a plug-in communication module for 7KM PAC3200 and 7KM PAC4200 measuring devices and 3VA molded case circuit breakers.

It provides the following features:

• Standardized PROFIenergy interface to the measured variables
• The measured variables can be individually selected using a GSDML file. This permits use of cost-effective S7 CPUs
• Easy beter assignment using the device display and STEP 7
• Integrated Ethernet switching allows networking with short cables without additional switches.
• Direct integration in production machine networks using IRT (IRT = Isochronous-Real-Time)
• Full support of PROFINET IO (DHC, DNS, SNMP, SNTP)
• Device replacement without PG in the PROFINET assembly using LLDP
• Deterministic reversing time through ring redundancy (MRP)
• Modbus TCP communication
• Communication with powermanager or powerconfig
• 2 x Ethernet (RJ45) sockets
• Baud rates 10 and 100 Mbit/s.
• PROFINET IO, PROFIenergy and Modbus TCP protocols
• No external auxiliary power necessary
• Additional display via the device display and via LEDs on the module

All measured variables from 7KM PAC3200 and 7KM PAC4200 can be individually selected and cyclically transmitted by means of the GSDML file. This enables optimum use of the process image of the PROFINET controller, e.g. CPU 315-2 PN/DP of SIMATIC S7.

The measured variables can be read out in acyclic mode using PROFIenergy, a PNO protocol profile. Thanks to PROFIenergy, it is possible to assemble a power monitoring system with devices from various manufacturers using PROFINET.
