Temperature PID Controllers
Fuzzy Logic PID, Auto Tuning, and Soft Start features combine for
uncompromising, state-of-the-art control
Extech controllers now offer Fuzzy Logic enhanced PID and a Soft-Start feature that protects heaters from cold-starts.
PID plus Fuzzy Logic tackles even the most demanding applications, eliminating over-shoot, unwanted process
fluctuations, and drift. The Soft Start feature is ideally suited for processes, such as those employed in the Thermo-Plastics
industry, where careful, exact, and slow heating of product is required.
• Dual 4-digit LED displays for process and setpoint values
• 1/16 DIN (48VFL) and 1/4 DIN (96VFL) model dimensions available
• Easy programming & navigation with user-friendly
menus and tactile keypad
• Fuzzy Logic PID offers intuitive control simulating
human control logic
• Manual mode allows the user to override automatic
control and drive the controller output higher or lower
with the touch of a button
• One-touch Auto Tuning for quick setup and stable, precise control
• Two ‘Latching’ Alarm relays standard with 8 Alarm
modes plus advanced Timer modes
• Single stage Ramp and Soak program with Ramp-to-Setpoint
Limit that can be combined with the Soft Start feature for
critical process demands
• Accepts thermocouple and RTD inputs
• Select desired temperature display units (°F or °C)
from setup menu
• Select thermocouple input type (9 selections) or RTD input
(2 selections) from the display menu without the need for
hardware modification
• Complete with mounting bracket hardware and screw
terminals for easy wiring
