BTC-9300 is a 1/16 DIN size panel mount controller. The units are fully programmable for PT100 and thermocouple types J, K, T, E, B, R, S, N, L with no need to modify the unit. A programming port is available for loading the configuration data with no need to use the keypads on front panel.

The programming temperature controllers can be configured with multiple setpoints that are sequenced with pre-set timing criteria. The process and application needs will be your first concern when you want to choose a programmable temperature controller the number of segments and programs.

The Fuzzy Logic plus PID microprocessor-based thermo controller, incorporate two bright, easy to read 4-digit LED displays, indicating process value and set point value. The Fuzzy Logic technology enables a process to reach a predetermined set point in the shortest time, with the minimum of overshoot during power-up or external load disturbance.
