The invention provides an adsorption drier controller which includes a gas inletting circuit switch control device and a center controller. The center controller comprises a programmable logic controller that connects with a human-computer interface, an A/D convert module and a communication module for connecting with network; each outputting port of the gas inletting circuit switch control device connects with one outputting port of the programmable logic controller directly or through an intermediate relay respectively, the programmable logic controller is equipped with a control module setaccording with the adsorption drier working program in inside; the adsorption drier detects gas temperature of outlet air and heater outlet in control process, and processes control according with detected result, makes control more accurately and energy-saving. The adsorption drier controller processes operation not only through the human-computer interface, but also remote controlling, and alsoprocesses control through network. The adsorption drier controller is equipped with operation indication and fault warning device, has perfect function.
