‡ Enables direct RS-232 connection to personal computer using 900Builder™ Lite software. A Cat. No. 900-CP1X cable or equivalent is also r
equired.
 Provides two event inputs. Allows selecting up to 4 different pre-configured set points, controller Run/Stop or Auto/Manual mode, fr
om 2 external inputs.
 Heater burnout is not available for 0...20 or 4…20 mA analog output style 900-TC16 controllers such as the 900-TC16AC.
 To obtain 57.6 k baud rate, Series B communication units must be used with any 900-TC8 controller catalog number from the Product Selection table on the
pr
evious page.
♠ 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.
§ Series B provides 57.6 K baud rate.
Allows connection between a 900-TC8 with a 900-TC8232 option unit and a PC using 900Builder Lite software or PC with software and a
900-CONV RS232-to-RS485 converter.
