Key Characteristics
Dual-Channel Reference Inputs
2 Independent Channels: Accepts up to two separate transducer signals (e.g., from two different machine shafts or redundant shaft locations) per half-height slot.
Sensor Versatility: Directly interfaces with both proximity probe systems (such as the standard 3300 XL series) and passive magnetic pickups.
Signal Processing & Tracking Speed
Multi-Event Compatibility: Capable of reading non-standard gears or shafts tracking multiple events per single revolution up to a max threshold of 20 kHz.
Low-Speed Detection: Passive magnetic pickups trigger at a minimum of 200 rpm, whereas manual threshold settings allow proximity sensors to lock on from 1 rpm.
