The ISaGRAF iPAC-8000 Series (iP-8417/8817/8447/8847) is the ISaGRAF SoftLogic PAC from ICP DAS. Each WP-8xx7 is equipped with an 80186, 80 MHz CPU running a MiniOS7 operating system, a variety of input/output ports (Dual 10/100 Base-TX Ethernet Ports for iP-8x47, one RS-232/485 port, one RS-485 port and two RS-232 ports) and a range of I/O slots (4/8) that can be used to integrate high performance parallel I/O modules (high profile I-8K Series) or serial I/O modules (high profile I-87K series). Users can also choose RS-485 Remote I/O modules (I-7000 series) or expansion units (RU-87Pn or I-87Kn) plugged with high profile I-87K serial I/O modules. Compared to I-8xx7, iPAC-8xx7 series is 2 ~ 4 times faster!
