Base and variant modules
Each module comprises 2 individual modules.
● Base module with input filters, A/D converter, I/O port. Same module with same
fittings for all 4 variants.
● Plug-on variant modules with switching circuit to generate -15 V, power sources
and linearization. Each of the four variants has a module of its own, i.e. a
module with different equipment.
The user has access to the 4 potentiometers to set the offset for each individual
channel. This can be useful for adjusting the zero value (at -50 °C) for long
measurement cables.
All modules are set up in pairs (base and variant module) at the factory. The variant
modules must not be exchanged.
