Universal PID controller for process heating

The Tempco TEC14040 is a 1/16 DIN digital temperature controller built for industrial and HVAC process heating. It accepts universal sensor types and drives a solid-state relay output from a 90 to 250V AC supply. Dual red LED displays show process value and setpoint in a compact 1.87 by 1.87 inch panel cut-out.

Replaces basic on-off thermostats when stable

Switching from simple hysteresis control to PID reduces temperature overshoot and cycling on heating elements, furnaces or plastic moulding barrels. The upgrade is worth it when product quality or energy cost depends on holding a tight band around setpoint. Two alarm relays rated at 2A add independent over-temperature or fault signalling.

Limited by single-loop PID

The unit runs one control loop with a 5V DC solid-state relay drive, so it cannot drive contactors or analogue actuators directly. Panel depth of 4.96 inches requires adequate enclosure space behind the cut-out. Power consumption is 10 VA and the controller carries CE, CSA and UL markings for the 90 to 250V AC input range.

Questions about this item

What panel cut-out size does the 1/16 DIN controller require?

The unit fits a standard 1/16 DIN panel cut-out and measures 1.87 in wide by 1.87 in high.

How is the solid-state relay drive output wired during installation?

Connect the SSR drive terminals to the 5 V DC input of your solid-state relay, observing the polarity marked on the rear label.

Which components may need replacement after extended use?

The dual red LED display and the internal SPDT alarm relay rated at 2 A are the parts most likely to require replacement over time.
