Model R7E Ethernet Modbus/TCP Module

  • Compact, all-in-one package
  • 4 analog inputs, 16 discrete I/O or 2 analog outputs20 Series
  • 8 or 16 discrete I/O extension module added to the main module
  • Analog and discrete signals can be mixed
  • 1500 Vac full isolation

The model R7E Remote I/O module is a new addition to M-System’s varieties of R7 Series Compact Remote I/O.

The module has the power supply, network and I/O sections all in one piece. It provides an ideal solution for wiring saving system using Modbus/TCP protocols over Ethernet, efficiently transmitting a small number of I/O signals scattered around remote locations to a PLC and a graphic operator panel.

COMPACT & FLEXIBLE
Palm-top size compact basic modules (W115xH50xD54 mm or 4.53”x1.97”x2.13”) can handle either 4 analog inputs, 2 analog outputs or 16 discrete I/O signals. The module can be expanded with a 8- or 16-point discrete input and output extension module.
This makes it easy to implement a mix of I/O signals to meet exact needs of different applications, such as RTD inputs plus transistor outputs, or analog outputs plus transistor outputs.
In addition to DC voltage/current and temperature, potentiometer and AC current input modules are available.

TWO-PIECE TERMINAL BLOCK
The barrier strip screw terminal blocks on the basic module can be separated into two pieces, providing easy and fast assembly and maintenance by prewiring.

SIMPLE SETTING
Input sensor types or ranges are selectable with the DIP switches on the front panel. For setting IP address and subnet mask, connect the R7E to a Windows PC with a dedicated cable. The PC Configurator Software provides a dedicated screen for Ethernet setting.

SUPPORTING COMPLEX APPLICATIONS
Using different thermocouples for each of four inputs, scaling different voltage ranges for each of four inputs,... such complex configurations can be accommodated also by using the PC Configurator Software.

EXTENSIVE SELECTION OF I/O RANGES
The DC voltage/current input module provides eight voltage and three current ranges, which can be selected with the built-in DIP switches. Only minimal number of spare units are needed.

HIGH RESOLUTION FOR ANALOG SIGNALS
DC voltage/current input and output signals are converted to 0-10000 for 0-100% full-scale.

FULL ISOLATION
1500 Vac isolation is maintained between I/O, network and power input. Chennel-to-channel isolation is also provided.
