Quick Details

Place of Origin: Poland
Brand Name: Mbus
Model Number: 400

Specifications

The mBus 400 is a transparent converter from RS232 to M-Bus interface. You can connect 4 RS232 signal lines - RxD, TxD, CTS, RTS.

The converter operates as a M-Bus Master and allows you to power (connect) up to 400 standard M-Bus receivers (so called M-Bus Slaves) through M-Bus Master output. You can connect fewer devices at a higher M-Bus load over long distances. You can use mBus with any devices equipped with M-Bus interface, e.g. heat meters, electricity meters, gas meters, executive modules, recorders, measuring instruments.

The converter has LEDs indicating data transmission: transmission (TxD), reception (RxD), overload on M-Bus (ERROR), M-Bus ready (READY), power supply (POWER). Connection interfaces are made of screw connection terminal blocks. DIN rail mountable plastic housing (TS35)

Features

Many of industrial devices are equipped with RS-232 interface, like the iMod telemetry platform:

iMod is a GPRS Telemetry Module with additional application logic on demand - NEW iMod series devices. This is innovative powerful and open Linux based platform for any telemetry application. Functionality as ModBus Gateway/Router, Data Logging, SMS/email notification, web interfaceand many more.

Main functions of iMod are:

  • downloading data from NPE interfaces or outside devices using the Modbus, mBus, or other protocols
  • buffering the gathered data with the option of its archiving - Data Logger
  • giving monitoring systems (i.e. SCADA type) or other iMod or PLC drivers access to the data

iMod supports iModCloud.
