A3900 II – 1 channel

1 - Channel Online Monitoring System

The A3900 is a simple one channel online monitoring system. Measured value is displayed on the front panel and can be transferred to the control system through 4-20 mA current loop output. Green, yellow and red LEDs informs you about the machine/bearing vibration state. The A3900 unit includes one programmable output “ALARM” relay.
