Moore Industries-International, Inc.
Installation
Installation consists of
physically mounting the unit, grounding the instrument, and completing
the electrical connections.
Mounting
The HES is designed to snap easily onto 35mm Top Hat (EN50022) DIN rails.
Electrical Connections
When installing any Moore Industries product, always follow all local regulations and standards
for grounding, shielding, and safety.
Installation Category
All terminals are rated CAT 1.
Equipment Ratings
The HES does not generate hazardous voltages, it provides a low current (4-20mA) input or
Ethernet output. Products connected to the HES should be designed to receive this type of
input.
Input
The HES has a choice or either 1 or 4 channels HART inputs with the ability to individually
configure each channel as either a Primary, Secondary, or Disabled Master. Each channel
supports up to 16 HART devices in digital multidrop mode, or can support just one device in a
standard point-to-point 4-20mA loop configuration.
Four channel configuration can support up to 64 total HART devices for high density
installations. The HES communicates with all HART 5, 6 and 7 devices including smart valves,
multivariable flowmeters, pressure, pH, level, and temperature transmitters and more.
A transmitter excitation power supply on Channel 1 only: 25.8Vdc ±3%@35mA; capable of
powering multiple HART field devices configured as multidrop model. (See figures 3.1 – 3.4)
Output
The HES offers a standard one RJ45 connector for Ethernet.
Protective Earth Conductor
The Protective Earth Conductor shall be of equal or larger size wire than the other two power
conductors. The Protective Earth Conductor shall be the first conductor connected to the unit
when the unit is being wired. It shall be the last conductor removed when the unit is being un-
wired.
