OMX 103UNI
UNIVERSAL ISOLATED TRANSMITTER • UNI > U/I/F
The OMX 103 model series are programmable DIN rail mountable transmitters, designed for maximum efficiency and user comfort while keeping their favourable price.
Type OMX 103UNI is a multifunctional two-input instrument with the possibility of 8 input configurations easily adjustable in the instrument´s menu.
The instrument is based on a single-chip microcontroller with 24-bit A/D converter, which ensures good accuracy, stability and easy operation of the instrument. As a standard the instrument is fitted with a backlit LCD display, enabling clear projection of measured values and configuration settings.
