2. General Introduction to xLogic
Overview
xLogic is a universal logic module made by Rievtech.
xLogic is a compact, expandable CPU that can replace mini
PLC, multiple timers, relays and counters. Bridging the gap
between a timing relay and a low-end PLC. Each CPU has
a real-time clock and calendar and supports optional
expansion I/O modules to meet your control and
monitoring applications needs. Data adjustments can be
done via the onboard keypad and LCD display, or with
xLogicsoft. It can be either DIN-rail or panel mounted,
depending upon the needs of your application, and it is
available in 120/240 VAC as well as 12/24 VDC versions,
and it is an ideal solution for relay replacement
applications, simple control applications such as building
and parking lot lighting, managing automatic lighting,
access control, watering systems, pump control, or
ventilation systems in factory, and home automation and
applications in which cost is a primary design issue.
