The Sigmatek compact CPU module is made in the S-DIAS I/O line and has recently been expanded to use a matching CPU in a mini format. This is the CP 111, a unit that is 12.5 by 103.5 by 72 mm in size. It is an efficient model that uses an 800 MHz EDGE2 processor with a low loss total and an exchangeable Micro SD card plus zero-voltage safe RAM, 256 MB of DDR3 memory, a real-time clock and Ethernet, SUB and VARAN interfaces. The PS 101 is made with a high-performance DIN rail CPU and a buffer battery plus a CAN bus interface and USB host. This is ideal for multi-CPU projects and can work as a flexible system for all kinds of high-speed connections with a real-time link at a bus speed of 100 Mbit/s.
