Siemens 6ES7452-1AH00-0AE0 SIMATIC S7-400 FM 452 Cam Control 16DO 11DI 1MHz PLC I/O Module

The Siemens 6ES7452-1AH00-0AE0 is a SIMATIC S7-400 cam control module, FM 452, with 16 cam-track digital outputs, 11 digital inputs, and inputs for incremental (up to 1 MHz) or SSI absolute encoders. It runs from 24 V DC, draws up to 500 mA, and ships with a configuration package on CD. Each output switches up to 600 mA at 24 V DC.

Technical Specifications

Selection Notes

Sixteen independently switched cam-track outputs let this FM 452 replace mechanical cam switches on a single axis without adding a separate output module, provided the 600 mA per-output rating covers the connected loads. Support for symmetrical and asymmetrical incremental encoders as well as SSI absolute encoders means the same module works whether the machine's position feedback changes between projects, without swapping hardware — only the configuration.

Applications

Generates position-based switching signals on packaging, printing, and material-handling machines where mechanical cam switches would otherwise be used, reading feedback from an incremental or SSI absolute encoder mounted on the machine axis.
