Acuvim IIR-M DIN Rail Mount power meter is a revenue grade power meter with on-board datalogging that can be used to meter & monitor power consumption at electrical panels and energy consuming devices or systems. It offers a wide array of communications options and standard MODBUS communications via a built-in RS485 port. This meter can also be used in conjunction with the free Acuview PC software for remote communications and control. This model does not have a display.

Since the Acuvim IIR-M is 0.2% accuracy and meets the ANSI C12.20 standard for revenue grade meters so it can also be used for tenant sub-metering applications.

With so many features for the low price, the Acuvim IIR-M offers unbeatable value.

Measurements
Acuvim IIR-M power meters can be used on any single or three phase electrical system up to 600V AC. Measurement parameters include volts, amps, frequency, power (apparent, active, reactive) & energy, power factor, peak demand, run time, THD and individual harmonics on both voltage and current to the 63rd harmonic.

Datalogging
The Acuvim IIR-M power meter has datalogging capabilities and can store up to 4MB of data.

Communications
There are four optional field upgradeable plug-in communications modules for the Acuvim IIR-M DIN Rail Mount power meter. These modules include analog I/O ports, digital I/O ports, Ethernet, or relays.

The table below shows which input/outputs are available on which modules:

Module	Digital In (DI)	Power for DI	Digital Out (DO)	Relay Out (RO)	Analog In (AI)	Analog Out (AO)
AXM-IO1	6	1		2
AXM-IO2	4		2			2
AXM-IO3	4			2	2

In addition, there are three communication modules for the Acuvim IIE - AXM-PROFI for PROFIBUS communication, AXM-NET for ethernet communications and the AXM-RS485 for an additional MODBUS RS485 communication port.

The Ethernet communications module enables MODBUS communication over Ethernet, plus offers configurable email alarms/alerts and a built-in web server for real-time data access through an Internet browser.

A total of 3 external modules can be stacked and used together with each Acuvim IIR-M DIN Mount meter. All modules are self-detecting and can be configured through the through Acuview Software.

Software
Acuvim IIR models are compatible with Acuview Software and communicate via MODBUS communications protocol using either the built-in RS485 serial port or the optional AXM-NET Ethernet Module. Acuview Software enables remote meter access for real-time monitoring and local PC-based datalogging. You can download a demo copy of Acuview software - instructions for installing and using the demo software are in this PDF document.
