K109UI
V - mA CONVERTER
WITH 3-POINT GALVANIC INSULATION
General Description
The K109UI instrument is a V - mA converter with 3-point galvanic insulation designed
for industrial standard voltage or current signals with passive input and active output.
Analogue/digital conversion takes place at 14 bit on every input range.
The instrument also provides the following functions:
Rejection programmable 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
driver, power supply available by bus, quick fit couplings by spring-type terminals, 3-
point insulation, onsite configuration by DIP-switch.
