| Series | 3500/25 |
| Model/Part Number | 3500/25-01-01-00 |
| Model Type | Keyphasor Card I/O Module |
Description
The 3500/25 Keyphasor Card I/O Module is an essential part of the 3500 Machinery Protection System. It is a half-height, two-channel module that provides Keyphasor signals to the monitor modules within a 3500 rack. The module receives signals from proximity probes or magnetic pickups and converts them into digital Keyphasor signals, indicating the precise moment when the Keyphasor mark on the shaft aligns with the Keyphasor transducer.
The system can accommodate:
- Normal configuration: Up to four Keyphasor signals.
- Paired configuration: Up to eight Keyphasor signals.
Specifications
Power Consumption:
- 3.2 Watts (typical)
