V3V-V3I-V4V-V4I

 

Display with voltage or current input

The instruments of the V_V, V_I series are multifunction microprocessor display units accepting either voltage or direct current input signals. They are particularly suitable to display force, pressure, weight values for process variables, analogue outputs of inverters and actuators, etc.


The carrying out with microprocessor and the use of modern analogue-to-digital conversion techniques enable to obtain excellent performances in terms of calibration easiness, resolution, stability, conversion speed, and cost by enabling the implementation of some functions of interest for the industrial applications (absolute/relative measures, programmable offset, etc.)


• V3: the measured dimension may be compared with 3 intervention thresholds that may be set for the enabling of as many relays, the status of which is displayed through a led.


Versions: V3V- displayed, V3V-3 displayed with 3 ON/OFF interventions.


Versions: V3I- displayed, V3I-3 displayed with 3 ON/OFF interventions.


• V4: the measured value can be compared with 2 or 3 adjustable thresholds for activation of many relays whose status is displayed via LEDs. Two analog outputs, a voltage 0-10V or -10 to +10 V, the other 4 ÷ 20mA 12-bit resolution. By calibration with self-learning is possible to adjust the amplitude of the input variable to the desired scale reading.


Versions: V4V- displayed; V4V-2 with 2 interventions with relay changeover; V4V-3 with 3 interventions with relay ON/OFF; V4V-T with analog output voltage and current; V4V-2T 2 interventions and analog output voltage and current; V4V-RS485 serial output RS485 MODBUS protocol; V4V-2RS485 2 interventions relay and RS485 serial output.


Versions: V4I- displayed; V4I-2 with 2 interventions with relay changeover; V4I-3 with 3 interventions with relay ON/OFF; V4I-T with analog output voltage and current; V4I-2T 2 interventions and analog output voltage and current; V4I-RS485 serial output RS485 MODBUS protocol; V4I-2RS485 2 interventions relay and RS485 serial output.
