EM (Electric Measurements and 24V Supply) Measure Terminals
Input Terminals for measuring voltage, current, supplying loop power,
and Frequency and pulse types refer specification sheet on
page no.
95 Section 6.6 and page no. 97 Section 6.13, 6.14.
Current Measurement
UC-12 supports current measurement using either UC-12 as the
loop power supply while at the same time measuring the current or
simply measuring the current while an external power supply is
used.
The following picture displays the connection for Current
Measurement for different mode. And
also different ways of
providing the supply power to the loop.
mA Current Measurement
In this mode UC-12 not providing any supply voltage. For
proper measurement the external device should capable of
providing the voltage supply. If the external device should not
capable, an external Power Supply should be connected in
series.
