P RODUCT D ESCRIPTION
The I-210+ is a solid-state electricity meter designed to measure energy in
residential and commercial applications that are wired for single-phase ANSI form
1S, 2S, 3S, and 4S services. The I-210+n meter, the functional equivalent of the
I-210+,contains additional circuitry to support poly-phase residential (3-Wire Y
Network) applications wired for ANSI 12S and 25S meter forms. The I-210+ and
I-210+n are configured for single-voltage applications up to 240 VRMS.
The I-210+ product family is designed to work with a broad range of third-party
AMR / AMI systems encompassing all types of unidirectional and bi-directional
communications media. The modular meter design allows utilities to integrate a
range of AMR choices to suit each application’s requirement inside a standard
metering platform. The I-210+ and I-210+n are available with an internal
connect-disconnect relay option within the same meter height and form factor.
The I-210+c meter provides a wide range of features, including the following:
• An extended range of software configurable features softswitches expand the
functionality of the meter. (Please refer to Softswitches on page 25 for more
information.)
• Alphanumeric display
• Standardized meter reading (ANSI C12.18) and programming (ANSI
C12.19)
• Improved MeterMate™ support for the I-210+ expands shop configuration
of the meter operating and display parameters.
• A Programmable Transformer factor display item
• Separate accumulators for each detenting mode supports net metering
applications with different delivered and received energy pricing.

4I-210+ User Manual
Physical Description
The I-210+ meter is furnished with a standard UV stabilized polycarbonate cover.
The sides of the cover are designed to be reflective to minimize solar heating and
obscure the internal components of the meter. Other cover options are available on
request.
The meter base assembly contains current sensing CTs and the necessary potential
connections to configure the meter for specific applications. The meter base
configuration is set in the factory and not designed for field modification (except
for 5th terminal location). The I-210+ is available with optional potential test links
in forms 2S and 12S.
The Liquid Crystal Display (LCD) indicates energy consumption and optionally
instantaneous demand or voltage on the lower three-digit informational display.
The display is soldered directly to the meter circuit board for high reliability. The
display features are covered in detail
AMR options may be installed on a supporting plastic bridge which mounts into
the meter base, or they may be mounted in the Nameplate Carrier itself, depending
on the size and construction details of the specific option.
A configuration port is located at the 3 o’clock position of the meter face. The port
is used in conjunction with a reset adapter that mounts over the cover and
MeterMate software (version 5.41 or greater) to reset accumulated energy to zero.
The port is intended for factory or shop use and is not designed for use in direct
sunlight. (Please see Configuration Port on page 19 for more information.)

theory of operation is described in conjunction with the following block diagram.

I-210+ User Manual 9
Chapter 2 • Product Description
Sensing Devices
Voltage is measured through a high impedance resistive voltage divider network.
Load current is converted to a scaled voltage signal by precision Current
Transformers. The scaled signals are inputs for the analog front-end of the
metering circuitry.
Metering and Reading of Data
The Meter chip contains a fully integrated analog-to-digital converter that samples
the scaled-down current and voltage signals. The meter chip integrates the product
of voltage and current over small intervals and accumulates the energy value in a
register.
The meter chip also contains an 8-bit microcontroller. It reads the accumulated
energy at defined momentary intervals from the meter chip and calculates the
energy consumption to be displayed. It uses non-volatile memory to store the
metered data and critical metering parameters.
Nonvolatile Memory
The I-210+ meter is equipped with 256 bytes of nonvolatile EEPROM memory
device. It is used to store the metered data, calibration parameters, and
configuration constants. Meter data quantities are updated at each power fail event.
Stored data includes error-detection provisions. The non-volatile memory does not
require a battery to retain information when line power is not present.
Power Supply
The I-210+ meter is powered from the AC main voltage of 120 V or 240 V for
single phase ANSI forms 1S, 2S, 3S, and 4S and 100 V, 120 V, or 240 Volt for
polyphase ANSI 12S meter forms. It has an operating range of ±20% of nominal
rating. It is a wide range solid-state switching type power supply; however, the
meter is configured for use at a specific nominal voltage rating.
AMR Interface
The meter has a ten-pin header (2x5 pin connector) that can be used to interface
with various AMR modules. Power and data signals allow an AMR device to
operate and retrieve metering data though this interface. The interface scheme
supports four different data communication methods and must be configured to
match the installed AMR device requirement.
Use of unlisted AMR/AMI modules shall result in voided warranty as Aclara can
no longer guarantee the safety and integrity of the product.
Disconnect Switch
The meter can be equipped with an optional under the cover 200A disconnect
switch in the same form factor.

10 I-210+ User Manual
Remote Disconnect Features
The Remote Connect/Disconnect (RCDC) feature provides the means to
disconnect the load side terminals from the line side terminals by activating a
switch that is controlled by the meter. This can be used for applications such as
Pre-Payment Metering (PPM), Emergency Conservation Periods (ECP), Demand
Limiting Periods (DLP), and Outage Management. The RCDC feature provides
the means to connect or disconnect service with direct switch commands. Presence
of load side voltage will be detected, and service will not be reconnected (the
RCDC switch will not be closed) while load side voltage is present.
The load control modes and direct switch commands share control of the RCDC
switch. The RCDC function can be in one of the following states (listed from
highest to lowest priority):
• Locked open,
• Locked closed,
• Armed for manual closure,
• Opened and held open,
• Open due to outage management,
• Open due to load control service disconnect,
• Closed with service connected.
If the meter detects load-side voltage, the actual switch state will remain open until
load side voltage is no longer detected.
The softswitches associated with the RCDC feature, which provide additional load
limiting features, are reference in Softswitches on page 25.
Outage Management and Restoration
The outage management function enables meter to open the closed switch in an
event of outage. Note that the meter does not enter into outage open mode, if the
switch was already open, before the outage occurred. The meter can be
programmed to reconnect the switch, after restoration of power.
Enabling Outage Management and Restoration in I-210+
The meter supports two programmable options to restore the connection by turning
the switch on:
• Immediately after the power is restored.
• Wait for a predefined time before turning the switch on.
