Introduction
This is the user’s manual for the Moore Industries HIM
Smart HART
®
Loop Interface and Monitor. It contains
all of the information needed to configure, install, oper-
ate and maintain this instrument.
About this Manual
Pay particular attention wherever you see a “
Note”,
“
Caution” or “WARNING ”.
Note– Information that is helpful for a procedure, con-
dition or operation of the unit.
Caution– Hazardous procedure or condition that
could damage or destroy the unit.
WARNING– Hazardous procedure or condition that
could injure the operator.
The HIM
The HIM allows up to three additional analog process
variable measurements from a multivariable transmit-
ter 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.
The HIM allows you to leave existing smart HART
transmitters and valves in place, yet still take
advantage of all the information they have to offer.
Model and Serial Numbers
Moore Industries uses the model and serial numbers
of our instruments to track information on each unit
that we sell and service. If a problem occurs with your
HIM, check for a tag affixed to the unit listing these
numbers. Supply the Customer Support
representative with this information when calling.
Inputs
The HIM accepts a HART digital protocol input directly
from a smart HARTmultivariable temperature, pres-
sure, level, flow transmitter or from a valve positioner.
Outputs
The HIM can be ordered with the following outputs.
2AO / 3AO
With this output, the HIM comes equipped with either
two (2AO) or three (3AO) programmable analog output
channels.
MB
Two redundant MODBUS RTU (RS-485) data links are
available for use.
MB1AO
Provides two redundant MODBUS RTU (RS-485) data
links with one analog output channel.
Options
The following options may be ordered with the HIM:
-1PRG / -2PRG
One (-1PRG) or two (-2PRG) user-programma-
ble alarm outputs; DPDT relay, 1 form C, rated
5A@250Vac, 50/60Hz, non-inductive (see Table 2 for
details). CSA Approved for use in General/Ordinary
Locations only.
-FMEDA
Unit comes with Failure Modes, Effects and Diagnostic
Analysis (FMEDA) data for evaluating the instrument
for suitability of use in a safety-related application.
-RF
Enhanced RFI/EMI protection (see
Specifications
for
details)
TX Power Supply
A transmitter excitation (TX) power supply (regulated
24.0Vdc ±10%@24mA) is standard on the HIM. You
may access it externally at the terminals shown in the
installation drawings.
