SC-DUALCON6

Isolating Signal Converter - 2 Outputs

16-36Vdc, 18-32Vac 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-DUALCON6 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 16

to 36 Vdc or 16 to 32Vac

For specials such as averaging of the input

signal, custom linearisation etc please

contact the sales office.
