Y E A R G U Isolating Signal Converter 2 outputs DUALCON The new DUALCON 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. Universal configurable input - user selectable 2 configurable Outputs - user selectable Full 3-Port Isolation Wide range AC or DC Supply Isolated Transmitter Supply Very High Accuracy, Low Cost Only 17.5mm Wide on DIN rail Options and ordering codes DUALCON - 6 90-264VAC supply 3 18-32VAC and 16-36VDC 6 Inputs Description Standard ranges are shown below - contact Sales for others. Full 3 port isolation is standard as is an isolated transmitter supply which can DC/AC Current and Voltage be used to power any standard 2-wire 4-20mA transmitter. 0-20mA, 4-20mA, 0-10mA into 15 The input type and range can be user selected using simple DIL switches 0-1V, 0-10V, 1-5V into 1M inside the unit. All RTD and thermocouple inputs can be fully linearised. Min and Max full scale ranges are: Non-interactive zero and span controls make adjustment of the unit, quick and DC Current 0 - 1mA 0 - 60mA simple. Bipolar DC Current 5mA 10mA Other features include optional inversion of the input signal, on either one or both of the outputs. DC Voltage 0 - 1V 0 - 300V* The unit is supplied with two power supply options either wide ranging ac or Bipolar DC Voltage 5V 10V dc. The ac version operates from any supply from 90 to 264VAC and the dc 2 Wire Pot 0 - 125 0 - 1k version operates from 18 - 32VAC and 16 - 36VDC. 3 Wire Pot 0 - 1k 0 - 100k For specials such as custom linearisation etc please contact the sales office. Note: For input voltages greater than 60VDC an IIR-Divider unit must be specified. Thermocouples Types E,J,K,N,R,S.T.B linearised or non-linearised Ranges: Wide range of inputs. Cold junction compensation (can be turned off) Upscale or downscale t/c burnout options Resistance Thermometers 2,3 or 4 wire PT100 or PT1000, linearised or non-linearised. Ranges: Wide range of inputs. Upscale or downscale RTD burnout options. Outputs DC Current and Voltage 0-20mA, 4-20mA, 0-10mA into maximum 1k 0-10V, 1-5V into a minimum 7k Others available up to a maximum of Current: 0-20mA.
