MR03 High Power Radio Transmission Module

The MR03 high power radio transmission module is destined to change the information transmission medium from the cable transmission with RS-232 and RS-485 interface into a wireless transmission in the radio channel in the non-licensed band 869.40 – 869.65 Mhz with the output power 500 mW. The module MR03 finds application in telemetric system applications, in which there is no technical possibilities to conduct a cable to connect devices in a wired network. In such cases , the module is used as a bridge which partially will carry out the transmission through the radio way. The maximal operation range of the MR03 module is 1.5 km in average, and depends on the terrain configuration and the applied antenna.
Accessible MR03 working modes:
l transparent,
l multipoint,
l point-to-point,
allow the creation of an extensive network of radio modules to fit the needs application requirements. Necessary parameter changes to the correct module work are carried out by means of the added configuration program ECon.

PD22 Data Logger/Concentrator

The PD22 data concentrator is destined for telemetering computer systems as an intermediate element in the data exchange between the object side and the master system. The data concentrator speeds up the data exchange between devices and the master system. Moreover it allows to increase the number of devices connected to the system. Two serial ports are used for communication. The first port (Port 1) having two RS-485 interface systems, destined to communicate with devices working in the object. The second port (Port 2) has RS-485, RS-232 and USB interfaces, destined to communicate with the master system through wire links.
An asynchronous MODBUS character communication protocol has been implemented on the serial link. The concentrator has a real time clock.
Parameter set of the concentrator serial link:
– address: 1 … 247
– baud rate: 12 00, 2400, 4800, 9600, 19200, 38400, 57600, 1152 00 bit/s,
– working mode:ASCII, RTU,
– information unit: ASCII: 8N1, 7E1, 7O1, 7N2,
RTU: 8N2, 8E1, 8O1, 8N1

The data concentrator realises following functions:
– readout of process parameters values from devices which are accessible as concentrator parameters,
– archiving of process data with a defined frequency, which are made available on demand for the master system (390000 records),
– archiving of emergency events (44400 events),
– data exchange consisting in transmission of demands from the master system to the specific device, eg. readout or parameter record.

PD51 – Converter of RS-232 / RS-485 Interfaces

The PD51 converter is a digital device destined to convert the RS-232 interface into the industrial interface RS-485. It enables the increase of the RS-485 bus range and the number of devices in the network with a RS-485 bus. It ensures the automatic steering of the data flow direction. The RS-232 interface is commonly accepted but since it has a limited range and restricted working possibilities, it is not used in industrial data  transmission systems. In almost automation systems and advanced control systems, the RS-485 interface is used because it has not such limitations and utilizes the differential procedure for data transmission, what is its main feature.

The PD51 converter is produced in two versions:

  • PD51-A – to be assembled on a rail, with opto-isolation,
  • PD51-B – as portable, without opto-isolation.

S4AI – Module Of Analog Inputs

S4AI module is designed to measure the standard signal (voltage, current, temperature, resistance, etc.) and to provide the measured values in a digital form via the MODBUS protocol. Input signals are divided into two groups of two inputs which are insulated with each other. RS485 interface and USB are isolated from the input, output signals and from the power supply. The module configuration is possible via the USB PORT or one of the available RS485 interfaces with the use of free e-Con software. e-Con software is available on the manufacturer’s website.

S4AO – Module Of Analog Outputs

The 4-channels analog outputs module is designed to convert numerical data to standard (voltage or current) signals, by means of the MODBUS protocol. The output signals are divided into 2 sets of 2 outputs, which are isolated between themselves. RS-485 and USB ports are isolated from outputs signals and the supply. The module setting can be done through USB or one of the RS-485 interface using the available for free eCon program.
