Introduction
BAS-3512/3520 is a standalone programmable controller specially designed ꢂor building automation applicationsꢀ Designed as a typical DDC (Direct Digital Controller), BAS-3512/3520
delivers various oꢂ onboard I/O including universal input, analog output, digital input and digital output, providing flexible options to satisꢂy versatile application requirementsꢀ It also
ꢂeatures powerꢂul BASPro programming tool ꢂor engineers to quickly develop their applicationꢀ BASPro delivers many ꢂunction blocks suitable ꢂor BA application, such as scheduler,
HVAC calculation, sequential control, PID control, alarm, and eventꢀ Its compact size makes it an ideal solution to ꢂulfill BA installation environmentꢀ The I/O expansion modules
(BAS-3018, BAS-3024, BAS-3050 and BAS-3051) provide more I/O points and make the system a scalable solutionꢀ
