RTD TRANSMITTER
COMPONENT IDENTIFICATION
INSTALLATION
Use Standard Rack (model: 10BX
❑
).
TERMINAL CONNECTIONS
Connect the unit as in the diagram below or refer to the
connection diagram label on the unit side.
CHECKING
1) Terminal wiring: Check that all cables are correctly
connected according to the connection diagram.
2) Power input voltage: Check voltage supplied to the rack
(model: 10BX
❑
). For the DC power source, be sure that
the ripple level is within 10% p-p.
3) Input: Check voltage across the terminal 1 – 2 with a
sensitive voltmeter.
(With 20
°
C or 68
°
F, approx. 220mV with Pt 100
Ω
, approx.
110mV with Pt 50
Ω
.)
If RTD wires are broken, the output goes over 100% (below
0% with downscale protection) due to burnout protection
function. Check leadwires in such a case.
4) Output: Check that the load resistance meets the de-
scribed specifications.

INSTRUCTION MANUAL
This manual describes necessary points of caution when you
use this product, installation, connection and basic mainte-
nance procedures.
POINTS OF CAUTION
■
POWER INPUT RATINGS
• Power input ratings are specified by the model number
suffix code. Check the power input voltage for the unit on the
specification label.
24V DC
±
10%, approx. 35mA with Voltage Output 1
approx. 55mA with Current Output 1
■
GENERAL
• Before you remove the unit or mount it, turn off the power
supply and input signal for safety.
■
ENVIRONMENT
• Indoor use
• When heavy dust or metal particles are present in the air,
install the unit inside proper housing and ventilate it.
• Do not install the unit where it is subjected to continuous
vibration. Do not apply physical impact to the unit.
• Environmental temperature must be within -5 to +55
°
C (23
to 131
°
F) with relative humidity within 30 to 90% RH in order
to ensure adequate life span and operation.
■
WIRING
• Do not install cables (power supply, input and output) close
to noise sources (relay drive cable, high frequency line, etc.).
• Do not bind these cables together with those in which noises
are present. Do not install them in the same duct.
■
AND ....
• The unit is designed to function as soon as power is
supplied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data sheet.
