SC-DUALCON3
Isolating Signal Converter - 2 Outputs
90-264Vac power supply
Selectable mA or Voltage output
Isolated Transmitter Supply
Very High Accuracy, Low Cost
Only 17.5mm Wide on DIN rail
Universal Configurable Input
2 Configurable Outputs, full 3-port isolation
The SC-DUALCON3 Isolating Signal
Converter can accept a wide range of
inputs including 4-20mA, thermocouple,
RTD and voltage signals. The units produce
two high level DC outputs of either voltage
or current.
Full 3 port isolation is standard as is an
isolated transmitter supply which can be
used to power any standard 2-wire
4-20mA transmitter.
The input type and range can be user
selected using simple DIL switches inside
the unit. All RTD and Thermocouple inputs
can be fully linearised.
Non-interactive zero and span controls
make adjustment of the unit quick and
simple.
Other features include optional inversion of
the input signal, on either one or both of the
outputs
The unit operates from any supply from 90
to 264 Vac
For specials such as averaging of the input
signal, custom linearisation etc please
contact the sales office.
