HIM
Smart HART Loop
Interface and Monitor
The HIM
The Moore Industries HIM HART Interface Module
unlocks the full potential of new and in-place HART
multivariable transmitters, valves, meters and other
smart instruments.
Converts HART to 4-20mA Signals
The HIM allows up to three additional analog process
variable measurements from a multivariable transmitter or valve with no additional process penetrations.
Installed transparently across the 4-20mA instrument
loop, the HIM reads the HART digital process data that
rides on the loop wires. It converts the digital information for up to three isolated analog (4-20mA) process
signals that are readily accepted by in-place control
systems, such as a DCS or PLC.
Provides Process and Diagnostic Alarms
Relay alarm trips (optional) can be individually user-set
either to trip when unwanted high/low process conditions occur, or provide a diagnostic health warning to
alert of loop or instrument fault conditions.
Takes Advantage of Legacy Instruments
The device lets you leave existing smart HART transmitters and valves in place, yet still take advantage of
all the information they have to offer.
Works with every Smart HART Device
The instrument can be programmed in minutes to interface with every HART-compatible monitoring and control device.

HIM
Smart HART Loop
Interface and Monitor
Configuring the HIM
One of the benefits of the HIM is that there are no
internal or external controls to adjust or settings to
change. All operating parameters are set using the PC
Configuration software.
Once these software settings are made, they are
downloaded to the monitor in the form of a Configuration
File and stored in the unit’s non-volatile memory. You
can choose to save a backup copy of the file on your
PC hard drive or external media. The HIM communicates with the PC through a proprietary communications cable to the PC’s serial (COM) port.
Begin by installing the PC Configuration Software.
Installing the PC Configuration Software
Refer to Table 2 for the equipment needed.
1. Insert the
PC Configuration Software
of the PC. Access the CD and open the
PC Configuration Software
2. Double-click the installation program located in
the folder. Follow the prompts to correctly
install the program.

Once the Configuration Program is installed on the PC,
the unit can be connected either into the loop or to test
equipment to simulate input and monitor output. With
the PC program, the user can then view and/or change
its operating parameters. To begin the process, connect
the HIM either into the loop (see
the Loop
Checking the HIM

) or into a configuration setup (see
).

Installing the HIM
There are two methods for connecting the HIM for
Mounting
The HIM is designed to snap easily onto 32mm, G-type
(EN50035) or 35mm Top Hat (EN50022) DIN rails.
configuration. The recommended method requires you
to install the instrument into the loop before it is
configured. The secondary method allows you to bench
check the HIM by attaching it to test equipment that
will simulate the input and monitor the output.
Electrical Connections
After mounting, you are ready to connect the HIM to
the loop. Each unit comes equipped with a transmitter
excitation terminal which allows it to supply power to
the monitored HART instrument, if necessary. Figures
Installing the HIM into the Loop
Installation consists of physically mounting the unit,

grounding the instrument, and completing the electrical
connections. To install the HIM into the loop for
configuration, use the equipment in Table 2 to hookup
the HIM into the loop as shown in Figure 3 (without
using the HIM to power a transmitter) or Figure 4 (using
the TX terminal to power a transmitter). If you need a

(EN55011, EN 50082-1, EN50082-2, etc.). Consult the
factory for the most current information on products
that have been CE certified.
• All input signals to, and output signals
from, Moore Industries’ products should be
wired using a shielded, twisted pair
technique. Shields are to be connected to an
earth or safety ground at the unit itself.
Recommended Ground Wiring Practices
Moore Industries recommends the following ground
wiring practices:
• Any Moore Industries product in a metal
case or housing should be grounded.
• The protective earth conductor must be
connected to a system safety earth ground
before making any other connections.
• The maximum length of unshielded input
and output signal wiring should be 2 inches.
Power Sourcing Parameters for General
Locations, Intrinsically Safe, and
Non-Incendive/Type N applications
In accordance with IEC 1010.1 Annex H
(all models), the input terminals must be
connected to and/or supplied from a certified
energy limiting Class 2 or a Separate Extra Low
Voltage (S.E.L.V.) power supply separated from
all mains by double/reinforced insulation.
