Heaters, Controls and Sensors has introduced the Model F48 1/16 DIN PID auto-tune temperature controller with Fuzzy Logic. The Fuzzy Logic plus PIM microprocessor-based controller series, incorporate a bright, easy to read 4-digit LED display, indicating process value or set point value, the company says.
The Fuzzy Logic technology from Heaters, Controls and Sensors 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.
The unit is powered by 11 to 26 or 90 to 250 Vdc/Vac supply, incorporating a 2 A control relay output. The second output can be used as cooling control, an alarm or dwell timer. Both outputs can select triac, 5 V logic output, linear current or linear voltage to drive external device.
There are six types of alarm plus a dwell timer can be configured for the second output. 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.
The input signal is digitized by using an 18-bit A/D converter. Its sampling rate allows the unit to control fast processes.
Digital communications RS-485 is available as an additional option.
