Options add functionality
A number of options let you customise the functionality of the Emotron FDU 2.0 and fully utilise the product according to your needs. Up to four different options can be combined.
Multiple pump or compressor control
Up to three I/O boards can be connected for multiple control of up to seven pumps or compressors without PLCs or other equipment.
Communication options include fieldbus communication via Profibus and DeviceNet, Industrial Ethernet communication via Modbus/TCP, EtherCAT, Ethernet-IP and Profinet, and serial communication via RS232 or RS485 with Modbus RTU.
PTC and PT100 sensors can be connected to control motor temperature and give process feedback without using a transmitter.Safe stop This option board offers protection from unexpected start during mechanical maintenance, in accordance to the standards IEC 62061 SIL2 and ISO 13849. No contactor is required.
Units from 90 A can be provided with liquid cooling. This allows you to reduce operating and maintenance costs, and the cabinet can have a protection class higher than IP54.
A 1st environment category 2 EMC filter is available as a factory-mounted option.
Reduced harmonic distortions
A 12-pulse rectifier offers cost-efficient reduction of harmonic current distortions. It reduces power losses in equipment such as transformers and conductors, and eliminates the need to over-dimension these components.
This option makes it possible to supply the control circuits via an external 24 V AC/DC supply to maintain communication and set up the system when 3-phase mains are not connected. It also provides communication backup if 3-phase main power supply fails.
IP21 Top cover
If units are wall mounted in electrical room, a top cover drip protection is available for IP 20 units 11-160 kW.
