➊ Enables direct RS-232 connection to personal computer using 900BuilderLite™ software. A Cat. No. 900-CP1X cable or equivalent is
also required.
➋ Provides two event inputs. Allows selecting up to 4 different pre-configured set points, controller Run/Stop or Auto/Manual mode,
from 2 external inputs.
➌ Heater burnout is not available for 0...20 or 4…20 mA analog output style 900-TC16 controllers such as the 900-TC16AC.
➍ To obtain 57.6 k baud rate, Series B communication units must be used with any Series A or Series B 900-TC8 controller catalog
number.
➎ Series B option units must be used with Series B 900-TC16 controllers. Series A option units cannot be used with Series B controllers
and vice versa.
➏ Series B provides 57.6 K baud rate.
