Before carrying out any operation it’s mandatory to read all the content of this user Manual. Only
electrical-skilled technicians can use the module described in this user Manual.
Only the Manufacturer is authorized to repair the module or to replace damaged components.
No warranty is guaranteed in connection with faults resulting from improper use, from modifications or
repairs carried out by Manufacturer-unauthorised personnel on the module, or if the content of this user
Manual is not followed.
The Z109PT2-1 module acquires an thermoresistance input signal, converts it to an analog format and send
it to an universal isolated output.
2. DESCRIPTION AND CHARACTERISTICS
Thermoresistance input:
(RTD): PT100,
PT500,
PT1000,
NI100.
2, 3 or 4 wires measurement, energising current 0.56 mA, resolution 0.1 °C,
automatic detection of interruption or RTD.
Variable from 240 sps with 11 bits resolution + sign to 15 sps with 15 bits + sign
resolution (typical values).
35 ms with 11 bits resolution, 140 ms with 16 bits resolution (measurement of
voltage, current, potentiometer).
