OMX 390LVDT

FAST ISOLATED TRANSMITTER • LVDT > U/I

The OMX 390 model series are very fast DIN rail mountable digital transmitters with a Teach-in function.
Type OMX 390LVDT is a transmitter for LVDT sensors. Setting of both the input and output ranges can be done conveniently by a DIP switch located on the side of the housing or from a PC via the OM Link SW. This device is based on a 32-bit processor, dual 24-bit ∆Σ ADC with PGA, demodulato, wake-up signal generator and 16-bit DAC, which guarantees high accuracy and excellent stability.

  • Power supply of LVDT sensor 1 / 3 / 5 Vac
  • 3- / 4- / 5- / 6-wire connection
  • Teach-in, Digital filters, Tare, Linearization
  • Quick configuration by DIP switch
  • PC configurable via USB port
  • Galvanic separation 2.5 kVAC
  • Power supply 10…30 VDC/24 VAC
