The "iS" series of meter/controllers can measure a wide variety of strain gage bridge and DC voltage intputs for all common load cells, pressure transducers, and most any strain gauge type of transducer. It is the first instrument of its kind, offering a wealth of powerful features and performance in an amazingly compact 1/32 DIN package or a 1/8 DIN package with 0.83" (21mm) high digits. The iS series handles input ranges of 0-100 mV, -100 mVdc to 1 Vdc, 0-10 V and 0-20mA. The iS series is easy to configure and scale to virtually any engineering units using the push buttons on the front panel, or using personal computer with the optional serial communications and free configuration software. The serial communications option includes both RS-232 and RS-485 on one instrument, and the straightforward OMEGA ASCII communications protocol, as well as MODBUS protocol. The iS series includes built-in excitation for transducers, selectable as 10 V at 100 mA or 5 V at 60 mA. The CNiS series controllers feature a choice of two optional outputs: Form C SPDT (single pole double throw) mechanical relays, solid state relays, DC pulse, and programmable analog output selectable for either a control function or retransmission of the process value. The iS series features the iSeries totally programmable color display that can change colors between Green, Amber, and Red at any setpoint or alarm point.
