Voltage and current measurement modules
UI
modules are equipped with 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 the sensor connection easier, the inputs are grouped
and all the ground terminals are common but separated from the power supply and other
modules.
The voltage inputs parameters are:
–
Name
– each built-in input already has a name given by the device and the user
cannot change it, for the description of the
Name
–
Unit
– parameter which displays the measurement unit -
V
,
–
Mode
– defines the measurement range,
–
Low limit
– defines the measurement level below which the
Lo
state will be
displayed in the logical channel,
–
High limit
– defines the measurement level above which the
Hi
state will be
displayed in the logical channel,
The current inputs parameters are:
–
Name
– each built-in input already has a name given by the device and the user
cannot change it, for the description of the
Name
–
Unit
– parameter which displays the measurement unit -
mA
,
–
Mode
– defines the measurement range,
–
Low limit
– defines the measurement level below which the
Lo
state will be
displayed in the logical channel,
–
High limit
– defines the measurement level above which the
Hi
state will be
displayed in the logical channel,

Mixed UIN/UID modules
Mixed
UIN/UID
modules have sixteen or twenty two inputs which allow to measure
current, voltage, resistance and temperature (using the NTC sensors) and can be equipped
with uninsulated digital inputs. A full hardware configuration description is in
Appendices 8.3.
UI4N8, UI4D8, UI8N8, UI8D8 – MIXED UIN/UID MODULES
. To make the sensor connection
easier, inputs are grouped and all the ground terminals are common but separated from
the power supply and other modules.
When the NTC inputs are used, it is recommended to use shielded wires and
connect the shield to the GND connector on the module.
The voltage inputs parameters are:
–
