NOVAR 2600 Operating Manual
Use terminals D1A (No. 23) and D1B (No. 24) for the digital input connection – see wiring examples in
appropriate chapter further below. The input is isolated from other instrument circuitry.
To activate the output apply voltage of specified range to the terminals.
ATTENTION !!! The “T”-output type models input voltage range of the digital input is
customized for 12 to 48 V DC control voltage - see table of technical parameters. It differs
from the “R”-output type models and it must be taken into account.. Voltage exceeding
maximum allowable may cause the instrument damage !!!
2.2.5 External Temperature Sensor
Some models are equipped with the EXT. TEMP external temperature sensor connector for
measurement of external temperature.
The input is designed for three-wire connection to a resistive temperature Pt100-type sensor. Connect
the sensor to the terminals No. 44 (
TA ), 45 ( TB ) and 46 ( G ) according example drawing below.
In case of two-wire connection, connect the sensor to the terminals TA and TB and short-circuit the
TB terminal with the G terminal. Note that the sensor cable loop impedance must be as low as
possible ( each 0.39 Ohms means additional measurement error of 1 ºC).
The temperature sensor can be ordered as the instrument’s optional accessory.
