Product Description
Key Features
- Exact product identity: SIPLUS S7-1500 TM PosInput 2 based on 6ES7551-1AB00-0AB0, with conformal coating.
- Encoder interfaces: 2 channels support RS-422 incremental encoders or SSI absolute encoders.
- Digital I/O: Each channel has 2 digital inputs and 2 digital outputs; all channels active provide 4 inputs and 4 outputs.
- Counting and position functions: 2 counters support counting frequencies up to 4 MHz with quadruple evaluation; incremental and absolute position acquisition are supported.
- Installation and supply: Rail mounting on an S7-1500 mounting rail; rated load voltage is 24 V DC, with a permissible range of 19.2 V to 28.8 V.
- Lifecycle data: Product lifecycle: Start of final year of support.
Applications
- Counting: The module supports counting with 2 integrated counters, continuous counting, parameterizable counter response, and parameterizable counting range.
- Position feedback: The module supports incremental and absolute position acquisition, including RS-422 incremental encoder and SSI absolute encoder signals.
