§Requires an option unit. Refer to Option Unit table on page 6
♣Interrupts require an event input option unit. Refer to Option Unit table on page 6.
³Determined by controller catalog number.
aOne of the controller alarm relays can be used as a second control output (i.e., a heating and cooling application).
‡Requires an option unit with an SSR output.
Requires addition of hardware. One current transformer (900-CT1 or 900-CT2) for single-phase and two current transformers for 3-phase detection. For the
900-TC16, the appropriate option unit must be purchased. Refer to Option Units in Product Selection on page 6.
