OMX 390PM

FAST ISOLATED TRANSMITTER • U/I > U/I

The OMX 390 model series are very fast DIN rail mountable digital transmitters with a Teach-in function.
Type OMX 390PM is a isolated transmitter. 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, fast 24-bit ∆Σ ADC with PGA and 16-bit DAC, which guarantees high accuracy and excellent stability.

  • Input 0…20 mA/4…20 mA/0…10 V
  • Output 0 / 4…20 mA / 0…5 mA / 0…2 / 5 / 10 V / ±10 V
  • Rate up to 7200 meas./s
  • Teach-in, Digital filters, Tare, Linearization
  • Quick configuration by DIP switch
  • PC configurable via USB port
  • Excitation 24 VDC
  • Galvanic separation 2.5 kVAC
  • Power supply 10…30 VDC/24 VAC
