Applications
- Time-stamped signal acquisition: Uses parameterizable digital inputs and outputs with time stamping for signal acquisition and output control.
- Counter and encoder acquisition: Uses counters and incremental acquisition for incremental encoders, including A/B tracks with 90° phase offset and pulse encoders.
- PWM output control: Provides parameterizable PWM output for digital output control.
Key Features
- Digital inputs and outputs: Has 8 parameterizable digital inputs and 16 parameterizable transistor outputs, with digital outputs in groups of 8.
- Signal functions: Supports time-stamped inputs and outputs, up to 4 counters, PWM output, oversampling, incremental acquisition, and counting for incremental encoders.
- 24 V DC supply: Load voltage 1L+ and 2L+ is 24 V DC, with a permissible range of 19.2 V to 28.8 V and reverse polarity protection against destruction.
- Encoder support: Supports asymmetrical incremental encoders, 24 V initiators, and 2-wire sensors; incremental encoder input frequency is up to 50 kHz and counting frequency is up to 200 kHz with quadruple evaluation.
- Diagnostics and isolation: Provides supply-voltage and short-circuit monitoring, diagnostic alarms, substitute values, status LEDs, and potential separation between channels and the backplane bus.
