The TOFFI has been designed to provide fault indication for both AC and EC type fan motors.
TOFFI continuously monitors either the tacho input or the external volt-free contact, and converts this to a volt-free contact output.
In the event that it no longer receives a signal the device will indicate a fault via its fault relay. When in fault mode the device isolates all power to the fan with a manual reset required to reset the fault.
Designed for continuous operation with a maximum rated current load of 8A at 40°C. Ambient on single phase 230 Volts ~ 50Hz supply. The normal equipment temperature range is -20°C to +40°C
