1/16 DIN Microprocessor Based PID Controller BTC-9090 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. Software has been refined over several years and offers a very logical menu structure and high noise immunity. Using an 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. FEATURES • Full 4 digit display. • Autotune PID. • Input user selectable. • 90-240 VAC supply. • Ramp rate function. • Timer function. • SEL function. • Optional 4-20 mA input. • 4-20 mA control output version. • Three level software access. • Safety: UL, CSA • EMC, LVD: CE 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. KEYPAD OPERATION TOUCHKEYS DESCRIPTION Advance the index display to the desired position. indexes advanced continuously and cyclically by pressing this keypad. Increased the parameter. Resets the controller to its normal status. Also stops auto-tuning, output percentage monitoring and manual mode operation. Allows more parameters to be inspected or changed. Long Scroll Press longer than 6 secs. Executes auto-tuning function. longer than 6 secs. Press Output Percentage Monitoring Allows the set point display to indicate the control output value. Manual Mode Execution Allows the controller to enter the manual mode. longer than 6 secs.
