Pulse/counter inputs can be used for versatile tasks, such as time-of-flight measurements between photoelectric sensors or rotation angle and speed measurements on rotary pulse encoders.
Each pulse module has up to 3 inputs (A,B,Z) which are sampled at 1.024 GHz
Input range - 30... + 80 V, with digitally adjustable trigger threshold
A: Pulse input (sine or TTL)
B: Direction of rotation (e.g. cosine)
Z: 0° identification – one pulse per rotation
Internal calculation of the angle φ and its temporal derivation φ'
As well as ∆φ and ∆φ' to a virtually uniformly rotating system
One (1) mathematical result can be displayed analogously for each pulse module
Output amplitude approx. ± 5 V
Tip timing in turbines
Torsional vibration analysis
Thanks to the analog outputs, you can connect an FFT analyzer f.e. and analyze the ∆φ signal
