Applications
- Incremental encoder counting: Counts signals from 24 V incremental encoders, including A/B tracks with 90° phase offset and zero track.
- Pulse measurement: Measures frequency and cycle duration from pulse generators and incremental encoder signals.
- Counter control: Supports hardware and software gates, event-controlled stop, synchronization via digital input, and comparison-value switching.
Key Features
- 2-channel counter module: 2 channels support 24 V incremental encoders or pulse generators, with 2 counters and a maximum counting frequency of 800 kHz with quadruple evaluation.
- Digital I/O per channel: Each channel has 3 parameterizable digital inputs and 2 parameterizable transistor outputs.
- 24 V supply and encoder supply: Rated load voltage is 24 V DC, with a permissible range of 19.2 V to 28.8 V. One common 24 V encoder supply serves both channels, with a maximum total encoder current of 1 A.
- Encoder and measurement functions: Supports A/B-track incremental encoders, pulse encoders, frequency measurement from 0.04 Hz to 800 kHz, and cycle duration measurement from 1.25 μs to 25 s.
- Diagnostics and mounting: Provides diagnostic alarms, hardware interrupts, supply-voltage monitoring, wire-break and short-circuit diagnostics, and mounting on an S7-1500 mounting rail.
- SIPLUS conformal coating: Has conformal coating for high reliability, with operation from -40 °C to 70 °C for horizontal installation and -40 °C to 40 °C for vertical installation.
