SPS008
The SPS8i is an independent over-temperature trip module designed solely for internal fitment to the SPS5 range of controllers. It is an optional safety device designed to protect kilns from over-firing. It behaves like a re-settable heat fuse. Operation of the trip is indicated by an otherwise hidden 'FAULT' legend on the controller front panel

Accuracy (at 20°C ambient)
Typical: +17°C
Maximum error: -5°C to +35°C
Cold Junction Compensation
not compensated
same as SPS5 series
This trip is designed for use mainly in Domestic & Light Industrial environments where electro-magnetic interference may cause a loss of accuracy of the trip temperature of up to 3°C. Specified accuracy will be restored when the interference is removed.
