The 3500/25 Enhanced Keyphasor® Module is a semi-high dual-channel module used to provide key trust numbers to monitor modules in Rack 3500. The module receives an input signal from the proximity probe or magnetic pickup and converts the signal into a digital Keyphasor® signal that indicates when the Keyphasor mark on the shaft coincides with the Keyphasor sensor. The 3500 mechanical protection system can accept up to four key trust numbers in normal configuration and eight key trust numbers in paired configuration.
