Applications
- Incremental counting: Counts 24 V incremental encoder signals, including A/B tracks with 90° phase offset and zero track.
- Pulse counting: Counts pulse-generator signals, including pulse encoders with direction and one impulse signal per count direction.
- Frequency and cycle measurement: Performs parameterizable frequency measurement and cycle duration measurement.
- Digital output control: Controls digital outputs with comparison-value switching and freely usable digital output functions.
Key Features
- Counter and encoder inputs: 1 counter supports 24 V incremental encoder or pulse-generator signals, including A/B tracks with 90° phase offset and pulse encoders with direction.
- Digital I/O: The module has 3 parameterizable digital inputs and 2 parameterizable transistor digital outputs.
- Counting performance: Maximum counting frequency is 800 kHz with quadruple evaluation; input frequency is up to 200 kHz.
- Measurement functions: Parameterizable frequency measurement ranges from 0.04 Hz to 800 kHz, while cycle duration measurement ranges from 1.25 μs to 25 s.
- Diagnostics and isolation: Diagnostics include supply-voltage monitoring, wire break, short-circuit, A/B transition error, and group error. Channels and backplane bus are isolated; isolation is tested with 750 V DC (type test).
- Supply and installation: Rated supply voltage is 24 V DC, with a permissible range of 19.2 V to 28.8 V. The module is usable with BU type A0 and has a mechanical coding element type B.
