The DRG Series signal
conditioner modules accept a
wide variety of input signals such
as thermocouples, RTDs, strain
gages, DC voltages/currents,
AC voltages/currents, frequency
and potentiometers and produce a
proportional conditioned process
output. The inputs and outputs are
both field configurable and offer
flexible wide ranging capability.
The slim housing mounts on a DIN
rail and is ideal for high density
installation. All modules provide
1800 Vdc isolation between the
input, output and power supply.
Field Configurable
One advantage of the DRG series
is the field configurable input and
output ranges. Each module can
be set to a number of ranges by
dip switch selection. Wide
ranging precision zero and span
potentiometers provide even further
adjustment. The signal conditioners
may be set for an almost limitless
number of ranges. Range
adjustment requires the use of a
calibrator or reference source.
