DIGITAL READOUTS
Digital readouts series VD3 can be employed in any industrial environment where it is necessary to measure voltage and cur­rents, speeds, angular or linear positions and any physical or chemical magnitude that can be transformed into an electrical signal. There are several versions available, indeed:
Vcc Voltage input, ±1 t5 Vdc, ±5t50 Vdc, ±50t250 Vdc selectable
LQRQ Input by potentiometer with settable scale range
LQRQ 2P Input by 2 potentiometers with settable scale range
Icc Direct current input 2 A max
Ica Alternate current input 2 A max
The display field can be chosen among three different solutions:
3 digits (999) Readout type VD30
3 /2 digits (1999) Readout type VD31
3 digits with steady zero (9990) Readout type VD300
The number of decimal digits can be preset. The calibration is performed by means of a trimmer placed on the rear case; the series named TF avails on a trimmer on the front case to adjust the scale range. Complying with C€ standard.
