Purpose and audience

The Tempco TEC56019 is a digital temperature controller designed for HVAC systems that need PID regulation with a 4–20 mA output. It suits engineers and technicians who require a 1/4 DIN panel-mount device operating on a wide 90–250 V AC supply.

Critical specification

The single specification that determines fit is the 4–20 mA analogue output, which must match the input requirement of the actuator or recorder being driven. Without that exact current-loop interface the controller cannot integrate into the control loop.

Thermals noise and power

The unit draws 15 VA from the AC mains, so heat dissipation inside the enclosure is minimal and no forced-air cooling is required. It has no moving parts, so audible noise is absent in normal operation.

Questions about this item

What does the 4-20 mA output actually drive in a live HVAC system?

It provides an analogue current loop that can modulate a valve actuator, damper motor or variable-speed drive proportional to the PID calculation.

How does the 90-250 V AC supply range affect installation on site?

The controller accepts any single-phase mains voltage between 90 V and 250 V AC without rewiring, drawing up to 15 VA.

Will the 1/4 DIN body fit in my existing panel cut-out?

The unit measures 3.75 in long, 1.87 in wide and 2.56 in deep, matching a standard 1/4 DIN panel opening.
