AT-1I-DS
Temperature transducer
with current output
Do not dispose of this device in the trash along with other waste!
According to the Law on Waste, electro coming from households free of charge and can
give any amount to up to that end point of collec� on, as well as to store the occasion of
the purchase of new equipment (in accordance with the principle of old-for-new, regard-
less of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the
environment and human health.
Purpose
The AT-1I-DS temperature transducer has been designed for
temperature measurement using the DS1820 series digital tem-
perature sensor and converting measurement result into an ana-
log current signal in the range of 4÷20 mA.
Features
» Continuous measurement of ambient temperature using digi-
tal temperature sensors DS1820, DS18S20 and DS18B20 (sen-
sor to be purchased separately);
» Compatible with the RT4 temperature sensors (temperature
range -30÷65°C) manufactured by F&F;
» Adjustable measuring range;
» Optical indication of the operation of the transducer and the
state of the connected sensor.

  • Page 1 Electro thrown in the trash or abandoned in nature, pose a threat to the environment and human health. Purpose The AT-1I-DS temperature transducer has been designed for temperature measurement using the DS1820 series digital tem- perature sensor and converting measurement result into an ana- log current signal in the range of 4÷20 mA.
  • Page 2: Front Description

    Front description Mounting Installation of the transducer should be performed by an installer with appropriate qualifications and experience in connecting electrical installations. It is recommended to use high quality power supplies with a good output voltage filtering ratio to power the transducer.
  • Page 3 Do not route signal cables, especially the cable for the temperature sensor, in parallel with other power cables. It is recommended to use a 3-core shielded cable to con- nect the temperature sensor. The shield of the cable on one side must be connected to PE. It is recommended to use a UTP twisted-pair cable to connect the power supply and the receiver.
  • Page 4 Power Maximum resistance of supply the receiver 375 Ω 12 V 500 Ω 24 V 1000 Ω 30 V 1200 Ω 4. Connect the temperature sensor to terminals 10-12 according to the color markings of the RT4 sensor, or the pinout of the DS1820 sensor.
