Ethernet ECC21 communication card
The ECC21 is an optional Ethernet communication card. It may be installed in the
slot in the Circuit Monitor intended for options. It has two main functions:
b equip the Circuit Monitor with a fast Ethernet connection over a 10/100 Mbits/s
copper link or a 100 Mbits/s fiber-optic link
b serve as an Ethernet gateway for devices daisy chained to its RS 485 ModBus
port.
The ECC21 card also includes a server for six HTML pages that may be consulted
by a standard web browser. These pages can be customised using WPG software
and display information from the host Circuit Monitor and/or devices connected to its
ModBus port.

CVM current/voltage module
This is the CM4000 acquisition module for currents and voltages. It is supplied
already installed on the CM4000. If the Circuit Monitor must be recalibrated, this is
the only module requiring recalibration. It may be installed and removed in the field.
This module may also be replaced in the field by a CVMT module to transform a
CM4000 into a CM4000T.
Part number
Current/voltage module for CM4000 CVM

CVMXR current-voltage module
This is the CM4000XR acquisition module for currents and voltages. Current
measurement range is extended to:
b 20 In for 1 second or 4 In continuously for 5 A sensors
b 100 In for 1 second or 20 In continuously for 1 A sensors.
The accuracy class is reduced to 0.5S for energy. As for the CVM, it can be added
and removed on-site. It is supplied already installed on the CM4000XR.
Part number
CM4000XR current/voltage module CVMXR
059217
CVMT current-voltage module
This is the CM4000T acquisition module for currents and voltages, i.e. it is suitable
for the detection of transient phenomena with a 5 MHz voltage-sampling rate. Similar
to the CVM, it may be installed and removed in the field. It is supplied already
installed on the CM4000T.
Part number
CM4000T current/voltage module CVMT
Memory extension kit
These kits make it possible to extend the Circuit Monitor memory to 16 MB or 32 MB.
