Technical properties

• Counting and position detection module for ET 200SP
• Interfaces:
  • Encoder signals A, B and N for 5 V TTL or RS422 differential signals
  • SSI interface with clock and data for RS422 differential signals
  • 24 V encoder supply output, short-circuit proof
  • 2 digital inputs for controlling the counting process, for saving or setting the counter or position value
  • 2 digital outputs for fast reactions depending on the counter reading, position value or measured value
• Counter frequency 1 MHz (4 MHz with four-fold evaluation)
• Counting range: +/- 31 bits
• Measurement function
• Parameterizable hardware interrupts
• Parameterizable input filters for suppressing interferences at sensor and digital inputs

Supported types of encoders/signals
