Product information
Overview
Applications
- Encoder counting: Counts pulse and incremental encoder signals, including A/B tracks with 90° phase offset, pulse encoders with direction and pulse encoders with one impulse signal per count direction.
- Position detection: Performs incremental and absolute acquisition and is suitable for S7-1500 Motion Control.
- Measurement functions: Performs frequency, cycle duration and velocity measurement with parameterizable measuring time and dynamic measurement period adjustment.
Key Features
- Counter and position detection: 2 integrated counters support incremental and absolute acquisition, continuous counting, parameterizable counter response and counting range.
- Encoder interfaces: Supports RS-422 and 5 V TTL push-pull incremental encoders, plus SSI absolute encoders with 10 … 40 bit parameterizable telegram length.
- Channel capacity and I/O: Provides 2 channels, 4 digital inputs and 4 transistor digital outputs; inputs and outputs are parameterizable, with 2 inputs and 2 outputs per channel.
- High-speed measurement: Input frequency reaches 1 MHz and counting frequency reaches 4 MHz with quadruple evaluation. Frequency and cycle duration measurement accuracy is 100 ppm, depending on measuring interval and signal evaluation.
- Supply and mounting: Load voltage is 24 V DC with a permissible range of 19.2 V to 28.8 V and reverse polarity protection. Mounting is on an S7-1500 mounting rail.
