The circuit monitor has a modular design to maximize its usability. In addition
to the main meter, the circuit monitor has plug-on modules and accessories,
including:
• Current/voltage module (CVM). A standard part of the circuit monitor is
the current/voltage module where all metering data acquisition occurs.
• Remote display. The optional remote 4-line display is available with a
back-lit liquid crystal display (LCD) or a vacuum fluorescent display (VFD).
The VFD model includes an infrared port that can be used to
communicate directly with the circuit monitor from a laptop and can be
used to download firmware, which keeps the circuit monitor up to date with
the latest system enhancements.
• I/OExtender. The I/O extender, located on the side of the circuit monitor,
enables you to “plug in” up to 8 industry-standard inputs and outputs.
Several preconfigured combinations are available, or you can create a
custom configuration.
• Digital I/O Card. You can further expand the I/O capabilities of the circuit
monitor by adding a digital I/O card (4 inputs and 4 outputs). This card fits
into one of the option slots on the top of the circuit monitor.
• Ethernet Communications Card. The Ethernet communications card
provides an Ethernet port that accepts a 100 Mbps fiber optic cable or a
10/100 Mbps UTP and provides an RS-485 master port to extend the
circuit monitor communications options. This card is easily installed into
option slot A on the top of the circuit monitor.
Table 1–2 lists the circuit monitor parts and accessories and their associated
instruction bulletins.
