DIGITAL ISOLATED CONVERTER mA OPERATION The device can be configured either by DIP switches located on the side of the housing or by PC using the OM Link SW. The same SW can be used to edit and archive all device settings, as well as to perform firmware updates and customer calibration. A standard microUSB cable is required for PC to device connection. Tech-in process can be performed for the measuring range currently selected using the front panel buttons. All settings are stored in the EEPROM memory (preserved even after power-off) Multifunction input (DC, PM, RTD, T/C, DU) 2x Analogue outputs, passive/active Quick conguration by DIP switch PC congurable via USB port Excitation 24 VDC Galvanic isolation 2.5 kVAC Simple instalation to DIN rail Power supply 10…30VDC, 24 VAC The OMX 300 model series are digital DIN rail mounted signal converters housed in an enclosure only 17.5 mm wide. The OMX 312UNI type is a galvanic isolated single-channel universal signal converter / splitter. It can be congured for 10 different input variants. Setting of both the input and output ranges can be done conveniently by a DIP switch located on the side of the housing or from a PC via the OM Link SW. You can also use this converter as a splitter into 2 analogue outputs. This device is based on a microprocessor with a 24-bit ∆∑ A/D converter, which guarantees high accuracy and excellent stability. STANDARD FUNCTIONS* PROGRAMMABLE INPUT Selection: of input type and measuring range Standard setting: any input values can be assigned to Min and Max values of the analog output Teach-in: any input values can be assigned to Min and Max values of the actual (unknown) input signal Manual setting: the known Min and Max values of the input signal can be set manually and any analog output values can be assigned to each of them at the same time ANALOG OUTPUT Type: isolated, congurable with resolution of 10 000 parts, rate < 3.5 ms Range: 0…10 V, 0…20 mA,4…20 mA EXCITATION Range: 24 VDC/35 mA, isolated FUNCTIONS Linearization: 100-point conversion of non-linear input signals by interpolation Tare: designed to reset display upon non-zero input signal Simulation: test mode in which range, value and duration of the step can be set Math functions: polynomial, inverse polynomial, logarithm, exponential, power, root DIGITAL FILTERS Floating average: from 2...30 measurements Exponential average: from 2...100 measurements Arithmetic average: from 2...100 measurements * this setting is only possible via the OM Link SW
