provide flexible, cost-efficient operation

The Allen-Bradley&reg Bulletin 900-TC temperature controllers feature flexible, multi-function control, easy-to-view LED displays, plus auto-tuning and self-tuning capability for improved control efficiency and fast startups. The controllers are available in 5-amp, 3-amp and 2-amp relay contact outputs; 12 V DC fixed voltage outputs to drive solid state relays; or 4- to 20- milliamp analog output. Dual 4-digit LED displays on the front panel of the controller allow operators to instantly compare the process and set point values, resulting in faster decisions.
