Peripheral Devices
Temperature Controller Connection to a Solid-State Relay (SSR)
The 12V DC output of a temperature controller is typically used to interface to an SSR, such as the Allen-Bradley Bulletin 700-Sx line. An SSR
provides high current (e.g., 40 A) switching capability plus longer life than a mechanical relay. See the Relays and Timers Selection Guide
(Publication 700-SG003x-EN-P) for additional information.

Controller Configuration from Keypad
Controller configuration of parameters can be done using the four keys on the bottom of the controller along with the two LED displays. The
configuration system is structured, which means a set path must be followed to get from one parameter to another.
User manuals, which provide details about configuring the Bulletin 900-TCx controllers, are available on-line at the Literature Library web site
