Universal Sensor Temperature Controller

The Tempco TEC55011 is a digital temperature controller designed for HVAC systems and industrial processes. It accepts universal sensor types and operates on a wide 90 to 264V AC input range. The unit provides PID control with dual red LED displays for clear monitoring. It suits engineers and technicians needing precise temperature regulation in compatible equipment.

Upgrade From Basic Thermostats

This controller replaces simple on-off thermostats when processes demand proportional-integral-derivative accuracy and alarm functions. The jump is worth it when you need two independent 2A relay outputs for heating and cooling stages. It also adds two dedicated alarm relays for safety monitoring. Buyers who only need basic switching without PID tuning or alarms will not benefit from the added complexity.

DIN Rail Mount Installation

The unit fits a standard 1/4 DIN panel cutout measuring 3.75 in by 3.75 in with a 2.56 in depth behind the panel. Wiring connects to screw terminals for the 90-264V supply, sensor input, and relay outputs. Common issues include miswiring the SPDT switch function or exceeding the 2A relay rating on inductive loads. Ensure the sensor type matches the configured input range before powering the 15 VA unit.

Questions about this item

What DIN cut-out size does the Tempco TEC55011 need for panel mounting?

The controller fits a standard 1/4 DIN panel cut-out and measures 3.75 in wide, 3.75 in high and 2.56 in deep behind the panel.

How do I wire the 90-264 V AC supply and the two 2 A relay outputs on the TEC55011?

Connect the AC line to the power input terminals; the load circuits go to the two SPDT relay contacts rated at 2 A each — a common mistake is forgetting that both relays share the same 15 VA power budget.

Which sensor types can I use with the TEC55011 and when might I need to replace them?

The unit accepts any universal sensor type supported by the TEC-4300 series; thermocouples or RTDs typically last several years but should be checked annually for drift or damage.
