EATON XV-303-70-B00-A00S07 / XV-303-70-B00-A00S07

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.

See also the MTL4850 datasheet for alternative HART solutions using a

32 channel multiplexer module ideally suited for use in conjunction with

emergency shutdown and safety systems.

Connectivity to HART Configuration and Instrument Management

Software :

The online access to the information contained within HART devices

allows users to diagnose field device troubles before they lead to costly

problems. Software can capture and use diagnostic data from HART

field instruments via the MTL HART connection hardware. This allows

users to realise the full potential of their field devices to optimise plant

assets, which results in significant operations improvement and direct

maintenance savings.

IMS products provide essential configuration, calibration, monitoring

and maintenance history functions for conventional analogue (4-20 mA)

and HART protocol compatible smart process instruments and field

devices. They deliver powerful tools to meet the need for standardised

instrument maintenance procedures and record keeping mandated by

some quality standards and regulatory bodies.

The MTL4851 and MTL4852 modules can also be located on HTP

SC16x termination boards for general purpose applications. HART loops

are simply wired through these HART Termination Panels and may be

grounded or floating circuits. The HTP boards offer a compact and cost

effective solution for general applications. CPH-SC16x backplanes are

ideal for signal loops requiring intrinsic safety (IS) protection, combining

multiplexer and IS isolator mounting. This offers considerable simplification

in wiring when compared to DIN-rail based solutions.
