General Description

The K109S instrument is a V - mA converter with 4-point galvanic insulation designed for
industrial standard voltage or current signals with passive input, active output and
auxiliary supply.
Analog/digital conversion takes place at 14 bit on every input range.
The instrument also provides the following functions:
Auxiliary Supply, completely floating, isolated from the other ports, with voltage unrelated
to the input power supply.
Current or voltage input.
Programmable rejection for 50 or 60 Hz mains frequency.
Additional reading stabilisation filter.
Inversion of the input and inverted output scales
Input Out-of-Range programmable to 2.5% or 5.0%
SQRT function.
Linearisation for horizontal cylindrical tanks.
The module is also characterised by its extremely compact size, coupling to 35 mm DIN
rail, power supply available by bus, quick fit couplings by spring-type terminals, onsite
configuration by DIP-switch.
