CONTROL FUNCTION
(SINGLE OUTPUT)
_________________________________________________________
Control action
PID control with auto-tuning
Fuzzy control with auto-tuning
_________________________________________________________
Proportional band (P)
0-999.9%, of full scale (FS), setting in 0.1% steps
_________________________________________________________
Integral time (I)
0-3200 sec, setting in 1 sec steps
_________________________________________________________
Differential time (D)

OUTPUT
(Single Output)
_________________________________________________________
Control output
One of the following three types is selected:
(1) Relay contact (SPDT)
220V AC/30V DC, 3A (resistive load)
Mechanical life: 10
7 times (under no load)
Electrical life: 10 5 times (under the rated load)
(2) DC SSR driver (voltage pulse):
15-30V DC at ON/0.5V DC or less at OFF.
Current– 60mA or less.
(3) 4-20mA DC:
Allowable load resistance– 600
Ω
or less.
