| The new INF8 counter is programmable for use as a quadrature counter, up-down counter, or angular counter (absolute code counter models are also available, consult sales for details). This instrument is designed for use with digital encoders, inductive, capacitive or optical pick-ups and ultrasonic sensors. In quadrature counting mode, the INF8 can be used with linear or rotational encoders. Counting direction is automatically selected by the momentary phase angle of the input. |
|
||||||||||||||||
The up-down counting mode is designed for fast bi-directional counting applications, while the angular counting mode uses an incremental encoder and counts quadrature pulses bi-directionally between 0 and 360°. The unit can be configured for either 1° or 0.1° resolution. Absolute code counter models can be used with Grey or Binary code resolvers. Models are available for single or multi-turn serial or parallel inputs. Parallel input models are available with 9 to 14-bit resolution, while serial input models are available with 8 to 19-bit resolution.
SPECIFICATIONS
INF8Q–Quadrature Counter: counting direction selected automatically by phase position of input signals A and B
INF8U–Up-Down Counter: input A represents input pulses,input B represents direction
INF8A–Angular Counter: counting direction automatically by phase position of input signals A and B; zero pulse from the external encoder sets the display to zero
