6 UPM6100 Connection Panel
Current inputs
The instrument can process measurements from
current
vices or other
transducers with 1, 2, 3 or
10V full scale outputs.
Inputs are not isolated; it is always necessary to
connect
Auxiliary power feeder Fuse Voltage inputs
85 - 250 V
AC or 90 - 250 V
DC Instrument power supplycircuit protection. Direct connection up to 600V
AC (750).Above this value the use of voltage
transformers is necessary. VT ratio's can
be programmed. Voltage interruptions longer than20-30msec are detected and
printed with a resolution of 0,1 s. transducers with double insulation accordingEN61010-1 safety standard.Flexible Rogowski transducers can be directlyconnected to the inputs without adaptors. The
programmable full
professional scales are 700 and 3000A.
Earth leakage input
A dedicated input, for measurement of earth leakage
current by 0-1V clamps or directly from 1000 turns
split-core CT.
Inputs for direct connection
Isolated inputs for direct connection of voltages up to
600(750)V L-L. Maximum current 20 (25)A RMS.These inputs can be programmed for use withtransducers with 1 and 5A output value (clamps or
current transformers).
Analog output (option) Digital inputs (option) Serial interface RS232 Temperature sensor supplier Digital output (option)
No. 1 optoisolated active outputthat can drive the load with no need
for an external power supply.It can be programmed as 0-20 or4-20mA and associated to one of
the main instantaneous values. No. 4 isolated inputs for voltage-free contacts. Can be used for
energy pulses counting, demand
syncronization or status indication
(according to installed options). The UPM6100 is provided withserial communication port RS232
to connect to a PC, modem or
Industrial ethernet gateway. Detects and displays theenvironmental temperature. No. 1 optoisolated output that
can be programmed for energy
pulse emission or alarm.
