Product information
Overview
Applications
- Counting: Supports continuous counting, event-controlled stop, hardware or software gate control, synchronization via digital input, and parameterizable counting ranges.
- Position acquisition: Supports incremental and absolute position acquisition and is suitable for S7-1500 Motion Control.
- Frequency and cycle measurement: Provides parameterizable measurement functions, with frequency measurement from 0.04 Hz to 4 MHz and cycle duration measurement from 0.25 μs to 25 s.
Key Features
- Counter and position decoding: 1 integrated counter supports incremental and absolute position acquisition, with counting frequency up to 4 MHz using quadruple evaluation.
- Encoder signal support: Supports RS-422 incremental encoder signals up to 1 MHz input frequency and SSI absolute encoder telegrams from 10 … 40 bit with clock frequency up to 2 MHz.
- Digital I/O: Provides 2 parameterizable digital inputs and 2 parameterizable transistor outputs, with electronic/thermal short-circuit protection.
- Output capacity: Each digital output has a rated signal-1 current of 0.5 A and permissible maximum of 0.6 A; total current per module is maximum 1 A.
- Supply and mounting: Uses 24 V DC rated supply voltage, supports BU type A0, and has a type B mechanical coding element.
- Diagnostics and engineering: Includes wire-break, short-circuit, A/B transition and SSI telegram diagnostics, with PROFINET GSDML V2.34 and PROFIBUS GSD Revision 5 support.
