Product Details

Siemens Networking Interface CPU

The Siemens Networking Interface CPU is a compact CPU with a voltage rating of 24VDC. It has 24 integrated digital inputs and 16 integrated digital outputs with current rating of 500mA and wide range of special attributes like 192KB work memory, 2-port switch, 1 Pt100 sensor, 4 high-speed counters (60kHz), 1st interface speed of 12 Mbit/s, front connector (2x 40-pole) and a micro memory card. It provides more power and additional features with an easy and simple upgrade path from the S7-200 series PLCs and includes many of the common features and instructions found in other models within the range.
Each CPU requires a Micro Memory Card (MMC).
