Introduction
EM511 is an energy analyzer for direct connection up to 45 A, for single-phase systems up to 240 V L-N. In addition to a digital input, the unit is can be equipped, according to the model, with a static output (pulse or alarm), a Modbus RTU communication port or an M-Bus communication port.

PFA models and SFA models
Easy connection function: irrespective of the current direction, the power always has a plus sign and contributes to increase the positive energy meter. The negative energy meter is not available.
PFB models
Bidirectional. Both kWh+ (imported energy) and kWh- (exported energy) are MID certified.
UCS (Universal Configuration Software)
UCS is available in desktop and mobile versions.
It may connect to EM511 via RS485 (RTU protocol, desktop version only).
UCS allows to:
- set up the unit (online or offline);
- display the system state for diagnostic and setup verification purposes
Overview of the UCS functions:
- Setting up the system with energy meter connected (online setup)
- Defining the setup with energy non connected, then applying it later (offline setup)
- Displaying the main measurements
- Displaying the state of inputs and outputs
- Displaying the state of the alarms
- Recording the measurements of selected variables
