Preset counter/frequency display VZ484801
Preset counter in 48x48 mm format; input: PNP, NPN, TTL; output: 2 relays
- Preset counter/frequency display in 48 x 48 mm format
- Universal AC and DC power supply
- Input frequency up to 100 kHz
- 2-line LED display
- Simple programming via keypad or software
- Two switching outputs

The compact preset counter VZ484801 can be used both as a preset counter and as a frequency display. Almost all commercially available pulse sensors can be connected via three function inputs (NPN/PNP/TTL). The counting direction can be determined and displayed via the internal phase discriminator or the corresponding wiring of the function inputs. A function input can also be connected via a potentiometer to specify the setpoint. In addition to an excellent price/performance ratio and high quality, the counter impresses with its robust, compact housing and brilliant display.
