| Model Type | Enhanced Keyphasor Module |
Description
The 3500/25 Enhanced Keyphasor Module is a half-height, two-channel module that provides Keyphasor signals to the monitor modules in a 3500 rack. It receives input signals from proximity probes or magnetic pickups and converts these signals into digital Keyphasor signals, which mark when the shaft’s Keyphasor transducer coincides with the Keyphasor mark.
This module supports:
- Normal configuration: Up to four Keyphasor signals
- Paired configuration: Up to eight Keyphasor signals.
Specifications
Power Consumption:
- 3.2 Watts (typical)
