R9WTU-EP

Remote I/O R9 Series

MULTI POWER MONITORING EXTENTION UNIT
(clamp-on current sensor type CLSE use)

Functions & Features
• Extension unit for Multi Power Monitoring Unit (model: R9xWTU) to expand current inputs.
• By using clamp-on current sensors, there is no need of current transformers.
• Up to 16 circuits can be measured with R9xWTU. (Common voltage measurement)
• Current sensors are easy to install in existing systems. Wide input range of 5 to 600 A is availabe.
