OMD 202UNI
OMD 202UNI
4/6 digit UNIVERSAL DISPLAY
The OMD 202 model series are large programmable displays designed for indoor and outdoor use with IP64 cover.
Type OMD 202UNI is a multifunction instrument with the possibility of configuration for 8 different input options, easily configurable in the instrument menu. By further options of input modules it is feasible to enlarge the number of inputs up to 4 (applies for PM). The instrument is based on a single-chip microcontroller with a multichannel 24-bit sigma-delta converter, which ensures good accuracy, stability and easy operation of the instrument.
Displays are suitable for projection of measured data in production lines and operations with legibility up to 80 m.
