In addition up to four sensors can be connected to monitor ambient conditions like temperature, humidity, acceleration (vandalism) and issue alarms via four relay contacts. Two continuous control outputs are also available for temperature regulation. Different strategies control the speed of the fans and the capacity of the cooling unit while status inputs monitor the fans for correct operation and indicate non-working units.
The RMS 490 brings together all the features of rack power and management with a tamper proof event log which saves all events that occur in the cabinet and an integrated two-line display that can be customised to show desired parameters. Integration with intelligent PDUs enabling current measurement for socket and single shutdown is all that is needed to complete the whole system.
