The diagram below illustrates the internal architecture of the Quantum safety analog
input module 140 SAI 940 00S.
The interface on the process side consists of 8 independent isolated input channels.
Each input is acquired by 2 identical circuits.
Here it is a current analog input.
In
measure 5 analog values between 4 and 20 mA.
The linearity of the measuring stages is checked at the same time.
The other mechanisms
140 SDI 953 00S are created.
The three input or output modules 140 SDI 953 00S, 140 SDO 953 00S and
140 SAI 940 00S, are also designed with the same electronic and software
subassemblies, with the aim of maximizing their reliability.
