EATON SDN90186 MOTOR CONTROL CENTER

The HCU16 HART units connect to 16 general purpose field instruments

while maintaining channel to channel isolation. Resistor conditioning

options are compatible with all types of I/O cards. It allows pass-through

connections for transmitter power supply, input signal and common.

The HCU16AO unit includes HART filters for use with I/O cards that are

incompatible with HART communication signals.

Customised backplanes and connection units are available to provide

direct connection from DCS I/O cables, replacing the standard termination

boards.

Solution-oriented and multifunctional

The devices‘ application oriented functions reduce the number of slice

cards required. This means, for instance, that digital outputs can be powered

and fused in groups, as well as switched off centrally. In addition, digital inputs

can perform additional counter functions, while analog modules include

additional functions such as a reference voltage, temperature measuring,

cold-junction compensation, etc.

The MTL4851 and MTL4852 HART connection system provides a simple

interface between smart devices in the field, control systems and HART

instrument management software run on a pc.

The system is based on 16-channel modularity to provide a compact,

easily configurable and expandable system. Using a standard RS485 serial

link up to 7936 HART devices can be connected on a single network.

For the optimum solution, choose from a range of general purpose

and IS termination boards. For maximum flexibility the HMM64 HART

backplane locates an MTL4851 master communications module and

up to three MTL4852 secondary interface modules, with each module

connecting to 16 field devices. General purpose HART connection units

and IS backplanes are available fitted with an cable interface connection

to the HMM64. This system can be extended with further HMS64 HART

backplanes linked to the master, each carrying up to four MTL4852

secondary interface modules.

With the XN300. you can rest assured knowing that you will find the ideal

configuration for the exact system solution you want.

The various modules are functionally designed for practical applications, minimizing

the amount of devices needed. This not only goes easy on your wallet, but also reduces

the amount of space required Convenient and easy to wire A plug-in connection system

makes it possible to quickly connect and replace modules,which in turn makes it much

easier to commission and service machines. Each module can accommodate up to 20

channels, which are distributed among five plug connectors as required for the application

at hand.
