Why choose PR
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 O 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.
