R9LWTU
Remote I/O R9 Series
MULTI POWER MONITORING UNIT
(Clamp-on current sensor CLSE, LonWorks)
Functions & Features
• Multi Power Monitoring Unit for LonWorks.
• By using clamp-on current sensors, there is no need of current transformers.
• Up to 8 circuits can be measured. (Common voltage measurement)
• Current sensors are easy to install in existing systems. Wide input range of 5 to 600 A is availabe.
• All measured values, counter values, display mode, setting data are stored in the non-volatile memory when power is off.
• By using SD card, data logging of current and power etc. with calendar is available.
