⋆ A current transformer (CT) is not provided with the unit.
‡ When the heating and cooling function or the heater burnout alarm is used, one of the relay alarm outputs can be used as the heating or cooling output or heater burnout alarm.
§ To implement the single-phase or three-phase heater burnout and heater short alarm function, an option module must be inserted into the 900-TC16 controller. For a list of 900-TC16 option modules, refer to the Option Units table, Option Units (Bulletins 900-TC8 and 900-TC16 — Only One Option Unit per Controller) The heater burnout and heater short alarm is available by mounting the appropriate option module into any 900-TC16 controller that supports (yes) the heater burnout (open) or heater short-circuit feature.
♣ The Bulletin 900-TC16 can have a second ON/OFF control output (SSR) by adding an option unit to the controller. Refer to Option Units table on Option Units (Bulletins 900-TC8 and 900-TC16 — Only One Option Unit per Controller).

♠ If the heating/cooling function is used, ALM1 will be used for the cooling control output and so the alarm output relay will not be available.
∇ Cat. Nos. with a C designator (e.g., Cat. No. 900-TC32C___) include RS-485 communications, but do not have an alarm (or cooling) output.
& Typically used for alarms or cooling output in a heat/cool application

Option Units (Bulletins 900-TC8 and 900-TC16 — Only One Option Unit per Controller)

The unit provides communications or event input functionality.

§ Enables direct RS-232 connection to personal computer using 900Builder™ Lite software. A Cat. No. 900-CP1X cable or equivalent is also required.
♠ 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.
∇ 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 previous 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.
