Modbus Protocol Direct Digital Controller / BAS controller 24VAC
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:
Network Control(RS485,Modbus Protocol)
PID Control
Programmable(7 days 4 periods)
Enforced Output
Alarm
I/O Correlative control
I/O Type Setting
