Siemens SM 331 Series PLC Expansion Module for Use with S7-300 Series, Analogue

Expand your SIMATIC S7-300 industrial network using this PLC expansion module from Siemens. It has eight inputs to increase the number of processing devices your system can communicate with. Using the analogue module, you can control a range of values such as surface temperatures, pressures and levels. Programmable parameters mean processes are started and stopped when set limits are reached, which enables systems to run with greater efficiency. A modular design makes the unit easy to integrate with existing networks and functions. Connect it to sensors, thermocouples or thermometers to streamline food, chemical and automotive manufacturing.

• Compact dimensions of 125 (H) x 40 (W) x 117mm (D) use minimal rack space to automate critical processes
• 13-bit resolution per channel to add multiple values and increase the ability to monitor or add steps into processes

For system safety, you can achieve galvanic isolation between the channels and the backplane bus. This means electrical circuits stay separate while allowing communication between devices.
