Accessories to expand your system
Ethernet communication card
The ECC is an optional ethernet communication card and can be installed in either
the CM3000 or CM4000.
It has two main functions:
■ Equip the circuit monitor with a fast ethernet connection over a 10/100 Mbits/s
copper link or a 100 Mbits/s Fibre-optic link
■ Serve as an ethernet gateway for devices daisy chained to its RS485 Modbus
port
The ECC card also includes a server for six HTML pages that may be consulted by
a standard web browser. The pages may be customised and will display
information from the host circuit monitor and/or devices connected to its Modbus
port.
Current/voltage modules
■ CVM
This is the CM4000 acquisition module for currents and voltages supplied
already installed on the CM4000. If the circuit monitor must be recalibrated,
this is the only module requiring calibration. It may be installed and removed in
the field. This module may also be replaced in the field by a CVMT module
(below) to transform a CM4000 into a CM4000T.
■ CVMT
This is the CM4000T acquisition module for currents and voltages suitable for
the detection of transient phenomena with a 5 MHz voltage-sampling rate. The
CVM may also be installed and removed in the field. Supplied already installed
on the CM4000T.
■ CVMXR
The extended range current/voltage (CVMXR) has the same metering capability
as the CVM, with the additional ability to detect and capture up to 100
amperes on directly connected loads for one second, or 20 amperes on
directly connected loads continuously. The CVMXR is a class 0.5 module.
Some applications for the CVMXR include motor starts or other events with
large inrush current characteristics.
Input/output blocks
The optional input and output blocks can be installed in either CM3000 or CM4000
■ IOC44 Card
This is an input/output card equipped with:
■■ 4 digital inputs 20-138 V AC/DC
■■ 4 digital outputs including 3 relay outputs and a static output that may be
programmed as a pulse output. It may be installed in the option-card slots
of the circuit monitor
There are three possible configurations: (1) IOC44 card, (2) IOC44 cards,
or (1) IOC44 card and (1) ethernet ECC21 card.
■ IOX I/O Extender (CM4000 only)
The IOX input/output extender may be equipped with up to eight plug-in input
or output modules. The entire unit connects to the side of the circuit monitor.
The input/out modules may be digital or analogue.
Three pre-equipped versions may be ordered directly, the IOX08, IOX0404 and
IOX2411. Other versions may be user prepared by ordering an empty IOX
extender and separate I/O modules. In this case, the IOX extender may be
equipped with up to a maximum of four analogue modules
