The new Productivity1000 stackable micro PLC is the super compact yet highly capable member of AutomationDirect's Productivity controller family. The P1000 is packed with many of the features of the Productivity series but housed in a smaller, slimmer design to provide space, budget and time savings. The full-featured P1-540 CPU ($169.00) has 50Mb memory; 4 built-in communications ports including micro USB, Serial RS-485, Serial RS-232 and Ethernet 10/100Mbps. The built-in Micro SD card slot provides data logging up to 32GB (card sold separately). The P1000 PLC supports up to 8 I/O modules for a total of 128 discrete I/O points or 32 analog I/O channels. A full lineup of 14 discrete and analog I/O modules is available. ProductivitySuite programming software is a free download and the P1000 starter kit ($399.00) has everything you need to get started.
