New Features
VTI21-ACS: Generic AC Sensor
The VTI21 can be employed as a two channel alternating current sensor for monitoring currents of up to 25A RMS. Typical applications include monitoring of AC track circuits and switch machines, however this versatile general purpose current sensor enables remote condition monitoring of any AC powered equipment.
See the AC Sensor documentation for more details.
VTI21-RFDM: Reed Frequency Division Multiplexer Monitoring
The well established Reed Track Circuit monitoring capabilities have been adapted to monitor Reed Frequency Division Multiplexing systems. The Reed FDM monitor supports a different set of frequencies than the Reed Track Circuit sensor:
| Channel | Frequency |
|---|---|
| F04 F16 F17 F19 F20 F26 F27 F36 F38 F39 F47 F48 F83 F84 F92 | 803.25 Hz 702.50 Hz 697.50 Hz 687.00 Hz 682.50 Hz 611.75 Hz 607.75 Hz 505.00 Hz 493.50 Hz 488.00 Hz 419.75 Hz 410.25 Hz 446.00 Hz 533.75 Hz 842.00 Hz |
The sensor reports the in-band current for these frequencies which can be used to infer the logical state of that "channel" and provide insight into the system's health.
