ISOCON-6
24V AC or DC POWERED ISOLATING SIGNAL CONVERTER

ISOCON-6 USERS GUIDE
1. INTRODUCTION:
1.1 Hardware Features:
The ISOCON-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.
The unit can be powered by any DC voltage between 12 and 36Vdc or 12 and 32Vac. For mains AC voltage the ISOCON-3 is
available which can be powered from any supply from 90Vac to 264Vac at 50 or 60Hz.
The instrument is packaged in a very compact 12.5mm wide enclosure which can be mounted on standard TS35 DIN-rail.
The unit can also be equipped with 1 digital output which can be either a relay or an open collector output, or a second analogue
output (see DUALCON-6). Note, units with above options are housed in a 17.5mm wide box.
1.1.1 Isolation Details
The ISOCON-6 has full 3 port isolation of 1000V between the Input Stage, Output Stage 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 Isocon-6 Isolating Signal Converter
1 Isocon-6 User Guide
If the instrument has been factory congured 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 conguration which is 4-20mA input and 4-20mA source output.
Please check that the details on the side label are correct, especially the power supply voltage.
If re-conguration is required please refer to Section 4 of this manual.

3.CONNECTIONS:
The ISOCON is housed in a compact DIN rail mounting enclosure, with 8 terminals, arranged in 4 rows of 2 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 and the power
supply and analogue outputs are on the top terminals.
The diagram below shows how to connect all the different input, output and power supply types.

ISOCON-6 USERS GUIDE
4. CONFIGURING THE ISOCON:
The ISOCON is an extremely versatile device which can support many different types of input. The unit is congured by turning the
power off, selecting the internal switch settings required and turning the power back on.
To open the Isocon, 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.
There are 3 switch banks, S1, S2, and S3, located inside the ISOCON as shown below:
Switch S1 and S2 congure the input type and range, and switch S3 congures the output type, range 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.
Warning: DO NOT OPEN UNIT OR ADJUST SWITCHES WITH POWER SUPPLY, INPUT OR OUTPUT CONNECTED
