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.
DUALCON-6 USERS GUIDE 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.
DUALCON-6 USERS GUIDE 4. CONFIGURING THE DUALCON ! WARNING ! 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.
DUALCON-6 USERS GUIDE 4.1.1 Voltage Input: Select the range from the table below and set Switch S1 to the required values. Voltage Range 0-1V 0-2V 0-4V 0-5V 0-7.
DUALCON-6 USERS GUIDE 4.1.2 Current Input Select the range from the table below and set Switch S1 to the required values.
DUALCON-6 USERS GUIDE 4.1.3 Millivolt (mV) Input Select the range from the table below and set Switch S1 to the required values.
DUALCON-6 USERS GUIDE 4.1.4 Potentiometer Input Select the range from the table below and set Switch S1 to the required values.
DUALCON-6 USERS GUIDE 4.1.5 Thermocouple Input Select the range from the table below and set Switch S1 to the required values.
DUALCON-6 USERS GUIDE 4.1.6 RTD Input Select the range from the table below and set Switch S1 to the required values.
DUALCON-6 USERS GUIDE 4.1.7 Output Configuration Select the range for Output 1 from the table below and set Switch S3 to the required values.
DUALCON-6 USERS GUIDE 5. CALIBRATING THE DUALCON When the unit is shipped the DUALCON will be calibrated for the input and output types and ranges noted on the side label. If this label is blank then the unit will be calibrated for 4-20mA input and 2 x 4-20mA source outputs. If the unit is re-ranged by the user it is necessary to re-calibrate the unit to obtain the maximum accuracy.
DUALCON-6 USERS GUIDE Green Green Zero Adjust Normal output 2 value. Press and release both buttons together to return to normal mode Use product The unit is now calibrated and ready for use. Note: The unit will retain the new settings on power down. When the unit is used to convert a thermocouple input it is important when calibrating to ensure that the thermocouple simulator employed is switched to automatic cold junction compensation and is at the same ambient temperature as the DUALCON.
DUALCON-6 USERS GUIDE 7. TROUBLESHOOTING The DUALCON has some built in self diagnostic functions. If the LED’s on the front panel are flashing then the fault mode can be found by counting the number of flashes between gaps and using the table below to locate the problem.
