Carlo Gavazzi EM111DINAV81XS1X Single-Phase Energy Analyzer
Description
A single-phase energy analyzer with Modbus in one DIN module
The Carlo Gavazzi EM111DINAV81XS1X is the EM111 single-phase energy analyzer in its AV8 range for direct connection up to 32 A on a 230 V line-to-neutral, 1-phase 2-wire system, with a RS485 Modbus RTU port (S1) and the standard, non-MID option (X). It measures active energy to Class 1 according to EN 62053-21 with an accuracy of 0.5% of reading on current and voltage, and it shows energy on a 7-digit backlit display with a touch keypad.
Because this is the non-MID version, the datasheet states that it cannot be used for fiscal (legal) metrology; it is intended for sub-metering, cost allocation inside a plant and machine monitoring. It is self-powered from the measured line and occupies a single 17.5 mm DIN module.

Choosing the right EM111 range code
The part number encodes the choices. AV8 is the 230 V, 5(45) A direct-connection range; AV7 is the 120 V version; AV5 and MV5 are for current transformers up to 300 A and 333 mV current sensors up to 600 A, and those two are available with the S1 output only. S1 selects RS485 Modbus, O1 a pulse output and M1 M-Bus. If the energy figures will be used for billing between tenants, the datasheet points to the MID-certified PF option instead of the X option used here.
Typical use and wiring notes
One EM111 per feeder or machine lets a PLC or an energy gateway read kWh, power, current and power factor over Modbus without extra transducers. Connect the load through the 6 mm2 measuring terminals, observe the 45 A continuous limit, and keep Modbus wiring as a daisy chain with end-of-line termination. The datasheet lists easy connection and wrong-current-direction detection, which helps when a feeder is wired the wrong way round during commissioning.

Frequently Asked Questions
What does the EM111DINAV81XS1X measure?
Single-phase energy (kWh, kvarh) and variables such as kW, kvar, V, A, PF and Hz on a 230 V 2-wire system.
What does the AV8 range code mean?
230 V L-N, 5(45) A, with direct connection up to 32 A.
What communication port does it have?
An RS485 Modbus RTU port, 9.6 to 115.2 kbaud, address 1 to 247.
