Advanced features

  • A multifunction user interface consisting of three pushbuttons and a 3-digit LED display for programming.

Application

  • The 2261 converts bipolar mV signals from transducers supplied directly by the device to standard current / voltage signals.
  • The 2261 is suitable for load cell application as well as other applications such as tank filling and draining, weighing with a taring function, measurement of cable tensile force, level control, signal conversion / amplification etc.

Technical characteristics

  • 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).
  • Sense input (with transducer supply used) for compensation for cable resistance to the transducer.
  • 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.
