Brainchild BTC-9090 Established Process and Temperature Controllers




The BTC-9090 is a new generation miniature controller using the latest SMD technology. Assembly is fully automatic and the units are checked and configured by computer. The software has been refined over several years and offers a very logical menu structure and high noise immunity. Using a unique command called SEL, the user has some flexibility in which parameters are accessible in level 2 of the menu.

This is of great value for users as it is easy to limit access to suit the application specifically. With 4 digit resolution and fully programmable decimal point, the 9090 can be configured for linear voltage and current inputs and with the addition of a single module, with 4-20mA control output. This is one of the most versatile units available. Manual control of the output is possible and Offset and Shift functions allow process values to be readily corrected for instinct offsets and in-site calibrations.
