3-color LED main display, auxiliary display and bargraph Multifunctional input (DC, PM, RTD, T/C, DU, Counter) Touch keys with haptic feedback and RGB backlighting Teach-in, Digital filters, Tare, Mat. function, Linearization DIN size 96 x 48 mm Power supply 10...30 V AC/DC or 80…250 V AC/DC Comparators • Data communication • Analog output • Data recording CONTROLS The device is controlled and set by either five touch keys located on the front panel or via a PC. For easier navigation of the device menu, the keys are backlit in different colors and provide haptic feedback when pressed. Initial set up of the device is easily done using our Setup Wizard, which guides you step by step through the basic settings required to make the device operational. There are two menu levels, USER and PROFI. The PROFI menu is password protected and it allows access to all menu items. If necessary, a narrowed down USER menu can be created using only selected items. These can be any items you select. You can also define each item as „view only“ or with „can be modified“ rights. USER menu is not password protected. OM 403UNI can also be configured from a PC using our free OM Link software via USB-C or Bluetooth. This SW also lets you archive all settings, transfer them from one device to another, perform firmware updates and even device calibration. All settings are stored in the EEPROM memory, so they are preserved even after the device is turned off. OPTIONS COMPARATORS (Relays or Open Collectors) are designed to monitor two, three, four or six limit values. The user can select various output modes and functions to match specific operational requirements. Reaching one or more set limit values is indicated by signaling LEDs and by switching on/off the relevant output. DATA COMMUNICATIONOUTPUTS can transfer measured values to other display devices or directly to control systems with speed and accuracy. Galvanic isolated RS232 and RS485 interfaces are available, supporting ASCII, Modbus, Profibus and Profinet protocols. ANALOG OUTPUTSare ideal for applications where further evaluation or processing of measured values in external devices is required. The galvanic isolated analog output is universal with the option of choosing the type and range - voltage or current. RECORDING OF MEASURED VALUESis ideal for applications that require measured values to be analyzed retrospectively, or simply archived. Recording takes place in real time (RTC). Recording parameters (start and stop times as well as frequency) are user defined. In case of short-term events, recording can be continuous with writing speed equal to sampling rate. Data is stored either in the device‘s internal memory or on a USB-C flash drive. The OM 403 series are 6-digit panel instruments designed for fast and easy setup, as well as accuracy and reliability. The 403UNI is a multifunctional device that can be easily configured for a wide variety of input signals in the device menu. The setup and operation of the device are user-friendly, despite its versatility, by incorporating two displays, touch keys with color navigation and haptic feedback, as well as our Setup Wizard integrated into the meter. The device is based on a 32-bit processor and a multi-channel 24-bit ΔΣ ADC, which ensure high accuracy, stability and easy operation. STANDARD FUNCTIONS PROGRAMMABLE PROJECTION Selection:user can choose from different types of inputs and measuring ranges Standard:for both endpoints of the input range, any value can be set on the display, e.g. input 0...20 mA > 0...500.00 Teach-In: with this function, it is possible to assign any display values for the currently measured endpoints of the input signal, e.g. input 4.02...20.01 mA > 0...500.0 Manual:user can manually set the two endpoint values of the input signal and assign to them any display values, e.g. input 0.04…9.58 V > 0…700.0 Overall projection:-99999…999999 EXCITATION Fixed:24 VDC/1,2 W, it is suitable for powering sensors and converters COMPENSATION Leads resistance (RTD, OHM): automatic (3 and 4-wire) or manual in menu (2-wire) Probes (RTD): internal resistance between actual sensor and its terminal block Cold junction (T/C): manual or automatic (temperature of terminal block) FUNCTIONS Linearization: non-linear signal can be converted by up to 100-point linear interpol. Tare: zeroing the display when the input signal is not zero Offset: fixed offset of the initial value Min/max value: registration of min./max. values reached during the measurement Peak value: the display projects only the highest or the lowest measured value Mathematical functions: polynomial, 1/x, logarithm, exponential, power, square root Simulation: the device simulates its function without a connected input signal Log: recording of events and error messages with a date and time stamp DIGITAL FILTERS Floating / Exponential / Arithmetic average: f rom 2 to 100 measurements Rounding:setting the display step for the display EXTERNAL CONTROL Hold:stop measurement Lock: locking out the buttons Tare: activation and zeroing of tare Reset Min/Max: reset the min/max value Hold Min/Max: start the measurement to evaluate the Min/Max value Sample: start of one-time measurement Data recording: storage of measured values in the device memory Opening of a relay: enabling a relay to disengage
