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
