FUNCTIONS & FEATURES
The R7MWTU is a Multi Power Monitoring Module for
Specify a code from below for [1].
• Specify the specification for option code /Q
(e.g. /C01)
Modbus.
The R7MWTU uses clamp-on current sensors, there is no
need of current transformers.
Current sensors are easy to install in existing systems. Wide
input range of 5 to 600 A is availabe.
BASIC MODULE: R7MWTU–2[1]1–AD4[2]
All measured values, counter values, display mode, setting
data are stored in the non-volatile memory when power is
off.
CONFIGURATION
2: Single phase / 2-wire and 3-wire,
A ‘basic’ module can be attached with an ‘extension’
module (except R7MWTU-211-AD4)because of this, it is able
to use it as 2-circuit power and 8 discrete inputs module.
3-phase / 3-wire and 4-wire
[1] NO. OF SYSTEMS
1: 1 system, Di / Pi x 4 (internal power 5 V)
(no connection with extension module)
2: 2 systems
