Transmissor mV
Principais características

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 


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

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.


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.

Short circuit protected transducer supply which can be programmed to 5...13 VDC from the front.

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.
