7.9.5. Built-in inputs – Modules
7.9.5.1. Voltage and current measurement modules
UI modules are equipped in eight, sixteen or twenty four voltage or current inputs, but
there are also modules where half of their inputs are voltage and other half are current, see
Appendices 8.2. UI4, UI8, UI12, U16, U24, I16, I24 – VOLTAGE and CURRENT
MEASUREMENT MODULES
. To make sensor connection easier, inputs are grouped and all
ground terminals are common but separated from power supply and other modules.
Voltage inputs parameters are:
– Name – each built-in input already has a name given by the device and user cannot
change it, for description of Name parameter see Fig. 7.75 .
– Unit – parameter which displays measurement unit - V ,
–
Mode
– defines measurement range,
–
Low limit
– defines measurement level bellow which in logical channel will be
displayed Lo state,
– High limit – defines measurement level above which in logical channel will be
displayed Hi state,
Current inputs parameters are:
–
Name
– each built-in input already has a name given by the device and user cannot
change it, for description of
Name

High limit
– defines measurement level above which in logical channel will be
displayed

state,
7.9.5.2. Mixed UIN/UID modules
Mixed UIN/UID modules has sixteen or twenty two inputs which allows to measure
current, voltage, resistance and temperature (using NTC sensors) and can be equipped with
uninsulated digital inputs. Full hardware configuration description is in
Appendices 8.3.
UI4N8, UI4D8, UI8N8, UI8D8 – MIXED UIN/UID MODULES
. To make sensor connection
easier, inputs are grouped and all ground terminals are common but separated from power
supply and other modules.
When NTC inputs are used, it is recommended to use shielded wires and connect
shield to GND connector on the module.
Voltage inputs parameters are:
– Name – each built-in input already has a name given by the device and user cannot
change it, for description of
Name
parameter see
Fig. 7.75
.

displayed Lo state,
– High limit – defines measurement level above which in logical channel will be
displayed
