I/O Module; Fig. 10: I/O Module - M&C GENTWO PMA1000 Instruction Manual

The MUC O2S SM - printed circuit board is a multifunctional sensor module. The sensor
measures the pressure of the sample gas before and after the measuring equipment. The
sensor module measures the temperature of an unheated sensor and controls the tem-
perature of a heated sensor, like the paramagnetic measuring cell.
The MUC O2S SM has an internal data bus. The raw data acquired from the sensor trans-
mitter will be processed and transferred via bus, and then displayed on the
user-interface.

6.3.2 I/O module

Fig. 10: I/O module

The I/O module has one analog output. The parameter of this analog output is freely se-
lectable via GUI/HMI. There are also four High-side outputs and two relay outputs (dry
contacts). An internal data bus controls these outputs and switches the outputs 'On' or
'Off'.
