Single Ramp To Setpoint Fuzzy Logic PID Micro-Processor Based Controller
The BTC-9090 controller incorporates a dual 4-digit LED display indicating process and set-point values. Housed in a 1/16 DIN case measuring 48 x 48mm with 86mm behind panel depth, the units feature four touch keys to select the various control and input parameters. Using a unique command called SEL, a supervisor has the flexibility of determining which parameters are accessible by the user. Powered by 90-264 volt AC, the controllers incorporate a 5-amp control relay output and a 2-amp alarm relay output.
