เครื่องนับจำนวนแบบดิจิตอล Digital Counter
รุ่น 521 Series
คุณลักษณะ
The Codix 521 is a voltage powered pulse counter / position display for fast and slow count pulses, with 6-digit LED display for NPN, PNP input signals.
Equipped with 4 count input modes: count direction, difference, addition, quadrature (phase discriminator) x1, x2 and x4.
- Fast count input – input frequency max. 60 kHz.
- Robust housing – IP65 protected.
- Very bright LED display, 8 mm high
- Position, difference, adding or count direction detection
- programmable for positive (PNP) or OV (NPN) switching input pulses.
- fast count input with an input frequency of max. 60 kHz, can be damped to 30 Hz for mechanical contacts.
- Short start-up time – detects input pulses just 16 msec after being switched on => no pulses are lost with a simultaneous motor start-up.
- Large keys – can also be operated when wearing gloves.
- Simple uniform menu-driven programming and operation
- possible to enter the programming also during operation with a confirmation prompt
- Individually programmable scaling : Multiplication and division factor (0.0001…99.9999), to display corresponding engineering units, e.g. position in 1/10 mm or packing units.
- • 4 different count input modes : 2-channel count input for detecting count direction, difference or adding mode, quadrature with x1, x2 or x4 evaluation.
- Freely programmable setpoint.
- As an alternative to the HTL inputs, devices are available with a 4 ... 30 V DC input level, for use as parallel displays to PLCs.
- Optional output - as zero signal.
