FnIO-Modul - 4-Kanal-Strom Eingangsmodul ST3234

The analogue input module processes signals with a standardized value of 4 mA to 20 mA. The input signal is transmitted electrically isolated to the system level with a resolution of 12 bits. The internal system voltage is used for the power supply. The input channels of the module have a common earth potential.

Power supply:

via system voltage 5 VDC

Power consumption:

max. 165 mA at 5 VDC

Isolation:

I/O and logic: optocoupler

Cross sections:

I/O cable max. 2 mm²

Connection technology:

Removable connection level (terminal blocks)

Dimensions (LxHxW):

12 mm x 99 mm x 70 mm

Operating temperature:

0 °C to 60 °C

Number of inputs:

4 channels single ended, no isolation between the channels.

Indicators:

4 x green/red for status, 1 x green/red for FnBus status

Resolution in steps:

14 bits with 0.9 µA/bit

Data width:

16 bit integer (2's complement)

Measurement error:

+0.1 % of the full scale value at 25 °C,
+0.3% of the full scale value at 0 °C and 60 °C.

Input impedance:

120 Ohm

Conversion time:

4 ms/all channels
