350025 BENTLY
The 3500/25 is an enhanced Keyphasor Module developed by Bently Nevada. It is a half height, dual channel module used to transmit key signal to the monitor module in the 3500 rack. When the keyphasor markings on the shaft align with the keyphasor sensor, the module uses a magnetic sensor or proximity probe to detect alignment and convert the input signal into a digital keyphasor signal.
Input signal specifications
Magnetic pickups or proximity probe transducers can send up to two transducer signals to each keyphase module. The input signal range of non isolated I/O modules is+0.8 V to 21.0 V, and that of isolated I/O modules is+5 V to -11 V.
Signals outside this range will be subject to internal limitations of the module. Passive magnetic pickup (3.3 Hz) requires a shaft speed exceeding 200 rpm.

Buffer Key Belief Signal
There are two coaxial connectors with buffered keyphasor outputs at the front of the rack. In addition, two buffered keyphase outputs with European connections can be accessed on the back of the rack.
Output impedance
The maximum output impedance of the buffer is 504 ohms
Keyphase sensor power supply
The power supply for the keyphase sensor is -24 Vdc, with a maximum of 40 mA per channel.
