RI-EMT4
RI-EMT4 is I/O extension module for PRO-series gateways.
Features
4 analog inputs designed to operate with 3-wire PT100 resistance thermomethers.
Power supply from Smart Extension Port
PT100 measurement ranges
In order to provide higher resolution and tolerance analog channels have automatic range change. Each channel has separate amplification value dependent on it's ADC readout.

PT100 tolerance table
Pt100 tolerance calculated assuming:
temperature coefficient = 0.003851 [1/°C]
temperature = 100 [°C]
ADC resolution = 4096 = 2^12
amplification = 8:1 or 18:1
