Get a handle on your automated process with this PLC CPU from Siemens. It carries signals between machines, automatically sending instructions from A to B, so you can enjoy efficient system control. Because it completes operations in just 0.07 to 0.72μs, it speeds through process management. There's space for up to 16 digital inputs and outputs, meaning this is a convenient option for running lots of modules at once. Thanks to integral support for full-duplex protocols, the device allows the movement of data in both directions for hassle-free communication. PLC CPUs like this are central to the management of medical equipment and automotive manufacturing systems.

• Slots into a rack for simple mounting
• Industry-standard RS422/485 connectivity for wide network compatibility
• Reverse-polarity protection on the inputs to cut the risk of damage from wiring errors
• Power loss of just 9W, minimising electrical consumption
• Works with shielded cables up to 1,000m in length to enable a flexible signalling layout

Yes, this CPU can set input delays of 0.1, 0.3, 3 and 15ms, so it's no problem to line your moving components up for smooth processing.
