Description
The 3500/50M Tachometer is a two-channel 3500 rack module that uses proximity probes or magnetic pickups to determine shaft speed, rotor acceleration and direction, and alarms on setpoints. Zero speed and reverse rotation modes use both channels.
Specifications (datasheet 141538)
| Parameter | Value |
|---|---|
| Channels | 2 channels |
| Input | proximity probes or magnetic pickups |
| Measurements | speed, rotor acceleration, zero speed, reverse rotation; peak hold |
| Output | can supply Keyphasor signals to the backplane instead of a 3500/25 |
| Status | not intended for overspeed protection — use the 3701/55 |
