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.

(1) No linearisation function connected
(2) Linearisation functions operate only in the 0..100% rated range, whereas for the
under-range and the over-range, the input signal is transferred without any alteration
(G=1). Continuity and monotonic quality of transfer guaranteed throughout the entire
range of measurement
(3) In the 0..1% section, the curve is linear with gain G=10 in order to avoid over-
amplification of the noise in the initial section of the measurement range.

Installation rules
This module has been designed for assembly on a DIN 46277 rail. Assembly in vertical
position is recommended in order to increase the module's ventilation, and no raceways or
other objects that compromise aeration must be positioned in the vicinity.
Do not position the module above equipment that generates heat; we recommend
positioning the module in the lower part of the control panel or container compartment.
We recommend rail-type assembly using the corresponding bus connector (Code K-BUS)
that eliminates the need to connect the power supply to each module.

1 -Attach the module in the upper part of
the rail.
2 - Press the module downwards.
1 -Apply leverage using a screwdriver (as
shown in the figure).
2 - Rotate the module upwards.
Inserting the module in the rail Removing the module from the rail
Using the K-BUS connector
1 - Compose the K-BUS connectors as required in order to obtain the number of positions
necessary (each K-BUS permits the insertion of no. 2 modules).
2 - Insert the K-BUS connectors in the rail by positioning them on the upper side of the rail
and then rotating them downwards.
sIMPORTANT: Pay particular attention to the po ition of the protrudent terminals of the
K-BUS. The K-bus must be inserted in the guide with the protrudent terminals on the left
(as shown in the figure) otherwise the modules are turned upside downs.
-Never connect the power supply directly to the bus connector on the DIN
rail.
-Never tap power supply from the bus connector either directly or by using
the module's terminals.

Electrical Connections
The module has been designed for spring-type terminal
electrical connections.
Proceed as follows to make the connections:
1 - Strip the cables by 0.8 mm
2 - Insert a screwdriver in the square hole and press it
until the cable lock spring opens.
3 - Insert the cable in the round hole.
4 - Remove the screwdriver and make sure that the cable
is tightly fastened in the terminal.
Power supply
There are various ways to provide the K Series
modules with power.
1 - Direct power supply to the modules by
connecting 24 Vdc power supply directly to
Terminals 7 ( + ) and 8 ( - ) of each module.

2 - Using the K-BUS connector accessory for the distribution of the power supply to the
modules via bus connector, in this way eliminating the need to connect power supply to
each module.
The bus can be supplied from any of the modules; the total absorption of the bus must be
less than 400 mA. Higher absorption values can damage the module. An appropriately
sized fuse must be connected in series to the power supply.
3 - Using the K-BUS connector accessory for the distribution of the power supply to the
modules via bus connector and the K-SUPPLY accessory for the connection of the power
supply.
The K-SUPPLY accessory is a 6.2 mm wide module that contains a set of protections
designed to protect the modules connected via bus against over-voltage loads.
The bus connector can be provided with power using the K-SUPPLY module if the total
absorption of the bus is less than 1.5 A. Higher absorption values can damage both the
module and the bus. An appropriately sized fuse must be connected in series to the power
supply.
