PID Control

Description:

HL/1-4884 is an intellectual building auto-control system (BAS) controller, which has 8 analog inputs, 8 digita

l inputs, as well as 4 analog outputs and 4 digital outputs. It has both PID automatic adjustment and 

enforcement modes, to realize field control and remote network control.Control objects, input and output 

signal type are optional.

Applications:
