Introduction

Moore Industries’ Programmable Isolated RTD
Transmitter (RIY) is a 2-wire, microprocessor-based
instrument that converts an RTD or ohms input into a
4-20 mA output. The output is field-configurable to be
linear with temperature or linear with an ohms input.

The highly accurate RIY features easy-to-use push
buttons, a rotary switch, and a SIP switch for field
calibration and configuration.

This manual contains descriptive, calibration, installa­tion, and operation information for the RIY. Also
included in this manual is a quick reference page
containing often referred to setup and hookup infor­mation (see appendix A).

Notes and cautions are provided throughout this
manual to help you avoid minor inconveniences
(NOTES) and equipment damage (CAUTIONS).

Description

The RIY is a loop-powered, RTD transmitter that
accepts an input from 2-, 3-, or 4-wire RTD’s, or a
resistance source. The RIY processes the input
signal using digital technology and produces a
proportional 4-20 mA output.

• Readouts in degrees Celsius or Fahrenheit, or
ohms (only on units with LCD’s)

• Sensor type and number to be input to the RIY

• Upscale/downscale drive

• Quick/standard ranging

• Keyboard lockout/enable

The RIY is available in two housing styles; a hockey­puck (HP) housing and a DIN-style housing. Both
housing styles have the same operational features
and offer the same options. The intended application
of the RIY must be clearly identified to determine
which housing style is most suitable.

The standard HP-style housing is equipped with
spring clips for mounting in explosionproof enclo­sures. An RIY packaged in an HP-style housing and
equipped with flange plates (FL Housing option) is
designed to mount on a flat surface or on relay tracks.
The configuration switches for HP-style units are
accessible through a removable panel at the rear of
each unit.

The all-aluminum DIN-style housing snaps directly
onto standard G-type or Top-hat DIN rails. The
configuration switches for DIN-style units are acces­sible through a removable panel on the upper right­side panel of the unit. The physical layout of the
configuration switches in DIN-style units is identical to
that of HP-style units.

Tactile push buttons, located on the front panel, are
used to set the zero and span (full-scale). The values
entered are stored in an EEPROM and remain, even
when power is removed, until the values are changed
by the user. The push buttons provide greater
calibration accuracy and stability than do potentiom­eter adjustments of non-microprocessor-based
instruments.

A 4-digit, liquid crystal display (LCD) is standard on
the RIY. (The RIY is available without the LCD.) This
display provides readouts of the applied input (either
in temperature or ohms), and it displays problem
codes. (The LCD is required for

Switches are used to configure several functional
characteristics of the RIY. Each of these switches is
accessible without disassembling the unit. The

specifications for the RIY.

The RIY is available with several optional features.
The following is a brief description of the most
popular options:

Unit Data Tracking – Model/Serial Numbers. Moore

Industries keeps a record of configuration information
on every unit it sells or services. This information is
keyed to the unit model and serial numbers.

The serial and model number for the HP-style RIY is
located on the back panel of the unit. The serial and

Calibration

Prior to shipment, every RIY is factory-checked using
automated test equipment. Duplication of the factory
check is not expected nor intended for the field.
However, field calibration procedures involving use of
the front panel push buttons and the configuration
switches are described in this section for field applica­tions.

Both the HP- and DIN-style housings are available
with the same options, and they have the same push
button and switch arrangements. The following
descriptions of the push buttons and configuration
switches pertain to both housing styles.

Using the Push Buttons

The RIY is equipped with a membrane panel that
contains four tactile push buttons used to set zero
and span (full-scale). Figure 1 shows the layout of
the membrane panel for both the HP- and DIN-style
units. Each push button is labeled with an Up or
Down arrow inside a circular background that is
contoured to the membrane-panel surface.

The functions of the push buttons are labeled
“ZERO”, “SPAN”, “SAVE”, and “CANCEL”. When the
arrows are pressed individually or in certain simulta­neous combinations, one of these four functions is
affected.

Pressing the ZERO or SPAN Up and Down arrows
simultaneously sets the unit to the calibrate mode (if
enabled through switch settings) for that particular
setting.

CAUTION

The push buttons are not designed to be

actuated with sharp, pointed objects.

Using a pen, screwdriver, or other sharp

object will damage the push buttons.

Using the Configuration Switches

A rotary switch and a single in-line package (SIP)
switch are used to configure the RIY for user-se­lectable operating and calibration parameters.

Figure 2 shows the layout of the configuration
switches and the switch setting options for SW301.
The switch settings for rotary switch SW302 are listed
in table 2. The reference designators and physical
layout of the switches in the HP- and DIN-style units
are identical.

The switches for HP-style units are accessed through
a cutout at the rear of the unit. The cutout is filled
with a small, removable panel. A narrow, slotted­head screwdriver may be used to gently pry the panel
off the unit to access the switches.

Switches for DIN-style units are accessed by remov­ing a small, L-shaped panel from the upper right-side
of the unit. This panel is bent over the top, right-side
edge of the unit and is secured with a single screw on
top. A Phillips-head screwdriver is required to
remove one screw securing the small L-shaped panel
to the housing frame.

The configuration switches are used to set the
following features:

SW301-1 — Displayed Temperature Type

ON – Sensor input displayed in Celsius
OFF – Sensor input displayed in Fahrenheit

This switch determines the type of temperature
units that will be displayed on the LCD. If an
ohms range is selected, the display will show
OHMS and this switch is ignored.

SW301-2 & -3 — Number of Wires or Sensors

These two switches determine the number of
wires for a single sensor input, or the number of
sensors of a multi-sensor input configuration.
Refer to table 2.

SW301-4 — Upscale/Downscale on Fault

ON – Downscale Output Drive on Fault
OFF – Upscale Output Drive on Fault

This switch determines the reaction of the RIY
output when an error is detected (during power­on diagnostics) or when an input or sensor lead is
physically open.

NOTES: 1. This column contains the Input Code for the model number of each RIY.

2. The lower table limit extends 5%, or more, of maximum span below the listed value. When this limit is

exceeded, the RIY will clamp at the limit value and the display will read “–LO–”. For ohms ranges, 0Ω is

the lower table limit.

3. The upper table limit extends 10%, or more, of maximum span above the listed value. When this limit is

exceeded, the RIY will clamp at the limit value and the display will read “–HI–”. For ohms range, 4095Ω

is the upper table limit.
