Specification
RTD’s, 2-, 3-, or 4-wire (single, dual, or triple sensors)
Ohms, 0-4000Ω
(refer to the Calibration Section for ranges)
4-20 mA – linear with temperature or ohms input (switch-selectable)
12-42 Vdc loop-power, standard
12-30 Vdc, I.S. version
Four front panel push buttons: used to set zero and span; SAVE
function (2 'up' buttons); and CANCEL function (2 'down' buttons)
Switches: Used to set the unit’s operating configuration (see Calibration
Section for application of switches)
Liquid Crystal Display: 4-digit LCD; diaplays input values; zero and
full-scale values; problem codes; and high and low table limit warnings

(switch-selectable)
Accuracy: ±0.05% of span (refer to table 2 for accuracy by input type)
Isolation: Galvanic isolation between input and output up to 1000 Vdc
Stability: ±0.1% of calibrated span for 6 months
Ripple: <10 mV P/P, maximum (up to frequencies of 120 Hz) measured
across a 250Ω load resistor
RFI/EMI Susceptability: 30 V/m – abc -0.1% of ohms reading as
defined by SAMA 33.1 (HP and DIN units)
Ambient Temperature Effect: All combined effect, ±0.006% of span/°C
±10 ppm of ohms reading/°C
Ambient Operating Temperature: –40 to 82 °C (–40 to 180 °F)
Storage Temperature: –40 to 100 °C (–40 to 212 °F)
NOTE: Refer to the Installation Section of this manual for housing dimensions.
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
model number for the DIN-style unit is located on
the right-side panel of the unit.
If product information is ever required, make a note
of the unit model number before contacting the
factory. For fastest assistance, also note the unit
serial number, and the job number and purchase
