Description
By limiting the number of faceplate keys to those strictly necessary, there is a larger space for the display. The miniaturisation achieved with SMT reduces the dimension and increases the reliability. The microprocessor enables the required performance to be selcte by means of setting only three parameters by following the configuration described later.
Features:
- Input from mechanical contact or Open Collector
- Start/ Stop and Reset inputs from machanical contact or AC voltage
- Configurable as Timer or Counter
- Five time bases, 1msec resolution
- Five ranges of counter prescaler
- Quartz timer
Main applications:
- Timer
- Double timer
- Cyclic timer
- Counter
- Double counter
- Cyclic counter
- Revolution monitor
- Delay timer
Technical Data
