F F AT-1U-DS Temperature Transducer with Voltage Output
Important Information
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 collection, as well as to
store the occasion of the purchase of new equipment (in accordance with the
principle of old-for-new, regardless of brand). Electro thrown in the trash or
abandoned in nature, pose a threat to the environment and human health.
Purpose
The AT-1U-DS temperature transducer has been designed for temperature measurement using the DS1820 series digital temperature sensor and converting measurement result into an analog voltage signal in the range of 1÷10 V.
Features
- Continuous measurement of ambient temperature using digital temperature sensors DS1820, DS18S20 and DS18B20 (sensor 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.
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.
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 connect the temperature sensor. The shield of the cable on one side must be connected to PE.
It is recommended to use a 2-core shielded cable to connect the voltage output, one side must be connected to PE.
-
Turn off the power to the switchboard.
-
Mount the module on a DIN rail in the distribution box.
-
Connect transducer’s power supply to the terminal 1 (+) and 2 (–).
-
The output signal is connected to the terminals 3 (+) and 2 (–).
-
Connect the temperature sensor to terminals 10-12 according to the color markings of the RT4 sensor, or the pinout of the DS1820 sensor.
-
Use MIN and MAX potentiometers to set the required measuring range.
The set maximum temperature (MAX) must be higher than the minimum temperature ( MIN ). Failure to meet this condition will block the transducer and signal an error. -
Switch on the power supply to the switchboard.

Transduction Characteristics
The value of the output voltage depends on the current temperature and the set
measuring range.
The shape of the characteristic is shown in the figure below:
Incorrect configuration of the transducer or sensor failure is indicated by special output signal levels given in the table below:
| Level | Description |
|---|---|
| 10,3 V | Short circuit at the sensor output |
| 10,6 V | No sensor connected |
| 10,9 V | Incorrect measuring range |
LED Signalling
The operation of the transducer is indicated by the LED signal light located on the front of the device.
| Signal light | Description |
|---|---|
| ON | The transducer and sensor are working properly |
| Short blinks every 1 second | Incorrectly set measuring range |
| Rapid, frequent blinking | Sensor error (short circuit at the output or sensor |
not connected)
