MODEL: R9MWTU R9MWTU SPECIFICATIONS ES-6221 Rev.11 Page 1/7 https://www.m-system.co.jp/ Remote I/O R9 Series MULTI POWER MONITORING UNIT (Clamp-on current sensor CLSE, Modbus) Functions & Features

• Multi Power Monitoring Unit for Modbus.
• 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. 125 (4.92) mm (inch) 140 (5.51) 80 (3.15) MODEL: R9MWTU–2001–AD4[1]
