DUALCON-6 USERS GUIDE
1. INTRODUCTION
1.1 Hardware Features
The DUALCON-6 is a universal input Isolating Signal Converter. It can accept
virtually every type of analogue input signal from millivolts to 40Vdc, mA,
thermocouples, RTD’s etc. It also produces 3 types of analogue output; voltage,
mA source, or mA sink on either of 2 analogue outputs.
The unit can be powered by any DC voltage between 16 and 36Vdc or 18 and
32Vac. For mains AC voltage the DUALCON-3 is available which can be
powered from any supply from 90Vac to 264 Vac at 50 or 60Hz.
The instrument is packaged in a very compact 17.5mm wide enclosure which can
be mounted on standard TS35 DIN-rail.
1.1.1 Isolation Details
The DUALCON-6 has full 3 port isolation of 1000V between the Input Stage,
Output Stage 1, Output Stage 2 and Power Supply for functional reasons.
2. UNPACKING
The instrument should be carefully inspected for signs of damage which may
have occurred in transit. In the unlikely case that damage has been sustained,
DO NOT use the instrument, but please retain all packaging for our inspection
and contact your supplier immediately.
The instrument comes with the following items as standard:
1 Dualcon-6 Isolating Signal Converter
1 Dualcon-6 User Guide
If the instrument has been factory configured the input and output details will be
listed on the Serial number label on the side of the unit. If this label is blank then
the unit will be set to its default configuration which is 4-20mA input and 2, 420mA source outputs. Please check that the details on the side label are correct,
especially the power supply voltage.
If re-configuration is required please refer to Section 4 of this manual.

3. CONNECTIONS
The DUALCON is housed in a compact DIN rail mounting enclosure, with 12
terminals, arranged in 4 rows of 3 terminals. Two rows are at the top of the front
panel and 2 rows are at the bottom. All the sensor input terminals are on the
bottom rows together with the second analogue output, and the power supply and
first analogue output are on the top terminals.
The diagram below shows how to connect all the different input, output and
power supply types.

4. CONFIGURING THE DUALCON
!
DO NOT OPEN UNIT OR ADJUST SWITCHES WITH
POWER SUPPLY, INPUT OR OUTPUT CONNECTED
The DUALCON is an extremely versatile device which can support many different
types of input. The unit is configured by turning the power off, selecting the
internal switch settings required and turning the power back on.
To open the DUALCON, 2 catches just below the outer terminal blocks must be
pushed in gently, one at a time. The front of the case can then be pulled and the
unit will come out of the box.
! WARNING !
Press here gently
There are 4 switch banks, S1, S2, S3 and S4, located inside the DUALCON as
shown below:
Switch S3
12 1
Switch S4
1 12
Switch S2
1 12
Switch S1
121
Switch 10 is OFF
Switch 11 is ON
Switch 12 is OFF
12 1110
ON = 1
OFF = 0
Switch S1 and S2 configure the input type and range, and switch S3 and S4
configure the output types, ranges and a few additional functions. The switch
settings are explained in the next few pages. The diagrams refer to switch
positions 0 and 1, with 0 being OFF and 1 being ON. This is illustrated in the
picture above.
