2261 mV Transmitter

Brand: PR Electronics
Request a Quote
  • Load cell amplifier
  • mV to current / voltage conversion
  • Front-programmable / LED display
  • Relative calibration of input span
  • NPN / PNP input for external taring
  • Supply for standard transducers
Features
  • A multifunction user interface consisting of three pushbuttons and a 3-digit LED display for programming.
  • Front error LED.
  • The analog input can be programmed for voltage in the range -40...100 mVDC.
  • The digital signal can be selected as either NPN or PNP.
  • Taring can either be by way of the digital input or from the front interface.
  • The analog output can be programmed to current in the range 0...20 mA or voltage in the range 0...10 VDC.
  • Transducer supply which can be programmed to 5...13 VDC from the front. It is up to the customer to ensure a max. load of 230 mA (e.g. 6 parallel 350 Ω load cells).
  • Mounting for a standard 11-pole socket which can be adapted for DIN rail or plate use with PR’s 7023 adaptor and 7024 mounting keying.Sense input (with transducer supply used) for compensation for cable resistance to the transducer.
