OMX 39RTD

OMX 39RTD

ISOLATED TRANSMITTER • THERMOMETERS Pt xxx  > U/I

The OMX 39 model series are inexpensive and simple DIN rail mountable analog transmitters. Type OMX 39RTD is a transmitter for galvanic separation of thermal resistance sensors Pt 100/500/1000. The transmitters have galvanic separation with insulation voltage of  600 V. They are therefore suitable as primary insulation for a majority of industrial applications.

  • input: Pt 100, Pt 500, Pt 1 000
  • output: 0…5 mA, 0…20 mA, 4…20 mA, ±20 mA
    0…2 V, 0…5 V, 0…10 V, ±10 V
  • galvanic isolation: 3,75 kVAC
  • width 22 mm
  • DIN rail mounting
  • power supply 10…30 V AC/DC or 80…250 V AC/DC
