10.5 Remote Monitoring Option
The SRL-250 to 6000 can be simply connected to an external supervisor system (otherwise known as
BMS or Building Management System).
To do so an (optional) RS485 serial card is fitted to the back of the microprocessor.
This allows direct connection to a BMS using the MODBUS RTU protocol, without the need for any
intermediate Gateway.
Once connected to the BMS it is possible to achieve:
Visualization of:
• Dew point & other temperatures
• Alarms
• Working hour counters
Control of:
• Dryer on/off
• Alarm reset (if allowed)
