EMOTRON FDU

Options add functionality

A number of options let you customize the Emotron FDU 2.0 functionality and fully utilize the product according to your needs. Four different options can be combined.

Multiple pump or compressor control

Up to three I/O boards can be connected. This opens for multiple control of up to seven pumps or compressors without PLCs or other equipment.

Communication

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.

Motor protection

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.

Liquid cooling

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.

EMC protection

A 1st environment category 2 EMC filter is available as a factory-mounted option.

Reduced harmonic distortions

A 12-pulse rectifier offers a 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.

Standby supply

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 is not connected. Provides communication backup if 3-phase main power supply fails.

IP21 Top cover

A top cover drip protection available for IP 20 units 11-160 kW if units are wall mounted in electrical room.
