to expand the main device of the series with the following main functions:
Two additional analog inputs, eg for monitoring the distribution of residual current from the total residual current between L1, L2, L3 and N and the residual current component in the supply line to the (central) grounding point.
Freely configurable absolute residual current limit values, relative residual current limit value with freely definable reference parameters (apparent power, effective power, etc.) as well as permissible residual current depending on the power consumption or residual current limit values for different power ranges including the respective pre-warning values.
Possibility of visual or acoustic warning when the residual current limit values are reached and forwarding of the excess via the communication interface to, for example, a building management system for permanent residual current monitoring.
Fourth current transformer connection for checking the neutral conductor dimensioning according to DIN VDE 0100-520 / IEC 364-5-5: 1993 of the resulting operating currents in the neutral conductor with asymmetrical, inductive or capacitive loads.
Modbus RTU to Modbus TCP - gateway function for network connection to higher-level software systems of max. 31 DIN rail or front panel built-in devices, energy meters or data loggers of the manufacturer's current product series.
Alternative option for integrating Modbus RTU-certified third-party products after a specific integration test via generic Modbus profiles.
Simultaneous supply of the communication interface and parallel operation of 4 Modbus TCP ports.
