From Alaron Instruments: The VDS-104 system is a versatile four-channel vibration monitoring system which combines a full featured Nema 4 monitor with 4-20 mA vibration transmitters, ideal for monitoring large industrial fans or any critical rotating machinery.

This complete vibration monitoring system can simultaneously monitor up to four locations. VDS-104 can be supplied with one, two, three or four VT series vibration transmitters, depending on your requirements. The system displays Velocity Measurements in inches/sec or mm/sec. Each channel supports a 4-20 mA current loop vibration transmitters [models VT100, 0-1 inch/sec; VT200, 0-2 inch/sec; or VT500, 0-5 inch/sec]. Two alarms per channel are provided and each alarm is adjustable across the entire measuring range and adjustable time delays are provided for each channel [0 to 20 seconds] to prevent nuisance alarms.

LED’s indicate status of alarms for each channel. A large dome LED flashes to visually indicate an alarm condition, with manual or automatic reset. Simple system setup via 4 pushbuttons on the front panel. The enclosure is Nema 4 rated with a clear front cover.
