 The OMEGA™ iSeries is a family of microprocessor-based instruments offered in three true DIN sizes with NEMA 4 (IP65) rated front bezels. All of the instruments share the same set-up and configuration menu and method of operation, a tremendous time saver for integration of a large system. The iSeries family includes extremely accurate digital panel meters "DPi" and single loop PID controllers "CNi" that are simple to configure and use, while providing tremendous versatility and a wealth of powerful features.

 
The DPi Series covers a broad selection of transducer and transmitter inputs with 2 input models.
 
The Universal temperature and process instrument (DPi models) handles 10 common types of thermocouples, multiple RTDs and several process (DC) voltage and current ranges. This model also features built-in excitation, 24 Vdc @ 25 mA. With its wide choice of signal inputs, this model is an excellent choice for measuring or controlling temperature with a thermocouple, RTD, or 4 to 20 mA transmitter. The strain and process instruments (DPiS models) measure inputs from load cells, pressure transducers, and most any strain gage sensor as well as process voltage and current ranges. The DPiS has built-in 5 or 10 Vdc excitation for bridge transducers, 5 Vdc @ 40 mA or 10 Vdc @ 60 mA (any excitation voltage between 5 and 24 Vdc is available by special order). This DPiS model supports 4- and 6-wire bridge communications, ratiometric measurements. The DPiS features fast and easy "in process" calibration/ scaling of the signal inputs to any engineering units. This model also features 10-point linearization which allows the user to linearize the signal input from extremely nonlinear transducers of all kinds. Programmable Color Display The DPi Series are 1/8, 1/16 and 1/32 DIN digital panel meter featuring the big iSeries color-changing display. The digits are twice the size of typical 1/8 DIN panel meters. The iSeries meters feature the only LED displays that can be programmed to change color between GREEN, AMBER, and RED. . Embedded internet and serial communications featuring optional "embedded Internet" (specify "-EIT" option) the iSeries are the first instruments of their kind that connect directly to an Ethernet network and transmit data in standard TCP/ IP packets, or even serve Web pages over a LAN or the Internet. The iSeries are also available with serial communications. With the "-C24" option, the user can select from the pushbutton menu between RS232, RS422, and RS485, with straightforward ASCII commands. If Modbus is required, we recommend our latest Platinum meters - DPPT Series.
