Expertise

Protect your heating application

If a temperature sensor is damaged or the SSR is short circuited in a furnace, the controller has no means of stopping rises in temperature. An internal alarm can help, but there is still some risk if the controller fails. This risk is eliminated by the built-in redundancy of the K8AK-TH alarm unit which can automatically switch off the power to the furnace.

Prevent overheating in cabinets

Temperature rises due to heat dissipation from SSRs within a cabinet can be too high for efficient operation. Simple ON/OFF control with the K8AK-TH can protect against overheating without the necessity and expense of running the fans continuously.
