The IRDN300 Communications Controller module incorporates state-of-the-art wireless and firmware technology designed specifically for the needs of plant automation and SCADA applications. The
IRDN300 is fully compatible with all existing IRDN series of VersaNet peripheral modules.
Versanet2 offers a variety of configurations allowing the selection of capabilities
to match the requirements of most applications. From simple point-to-point to complex multipoint network applications,
Versanet2 is capable of providing reliable and robust data communication. There are a number of additional I/O modules for Digital, Pulse, Analogue and Alarm signals, that allow expansion for larger systems.
Typical automation/SCADA applications require a radio transceiver that is highly optimised specifically for data. The
IRDN334 boasts a built-in UHF Transceiver proven on RDT's highly successful range of radio modem products the RM9600 and RM9634. The
IRDN334 is capable of operating on up to 64 channels in the frequency range 400-470MHz. Frequencies can be factory or field-programmed with ease. Easy to use configuration, monitoring and
set-up software facilitate fast and accurate installation and monitoring of the data link.
Where greater coverage range is required, an IRDN300 Controller Card can be used with a GSM or Wire-line modem. Note: the IRDN334 is supplied complete with a UHF radio module. It is possible to use the IRDN334 with a GSM or Wire-line modem used as a backup to the main UHF radio.
The IRDN300 range of modules offers full signal isolation making them suitable for use in the harsh environments often encountered in remote monitoring and control applications. The optional IP67 enclosure allows the
a Versanet2 node to be mounted in exposed areas which would otherwise require additional protection.
The rugged aluminium enclosure permits convenient installation in areas with space limitations.

Expansion I/O Modules
A range of I/O modules is available to allow the system to be expanded up to a maximum of 192 inputs per node. Inputs can be any combination of Analogue, Digital or Pulse. There are special combination modules, useful for constructing small nodes and an Alarm output module. A number of the modules can be used in Low Power Mode for use on remote sites where mains power is not available.
IRDN301 Digital Output Module
This module provides eight digital outputs to external devices in the form of changeover relays, fitted with arc suppression networks.
Digital outputs change state based upon instructions received from the Communications Controller
(IRDN300-xxx). These instructions may originate from a Digital Input at another node or via the Serial Data Highway for MODBUS applications. For exact configuration instructions please refer to the VersaNet2 User Manual (LIT0002).

GSM and Wire Line Options
GSM and Wire Line OptionsVersaNet2 has been designed to work with either a UHF radio, a GSM Modem or a Wire Line Modem, dial up or leased line. The GSM or Wire Line can be used as the main communication option or used as a back up for the UHF radio. In this case, if the radio link fails for any reason, the VersaNet Node would use the alternative modem. If a GSM modem is used, there is also the option to send pre defined SMS text messages, particularly useful to alert engineers to an alarm condition.
GSM Option
The VersaNet2 software, has been specifically designed to interface with the Wavecom WMOD2B dual-band GSM Modem. Other GSM Modems may work perfectly well with VersaNet2, but their operation cannot be guaranteed. For example, most modems use a similar command set in normal point to point mode, but they seem to use different protocols for SMS
messaging. Before using the modem, it will be necessary to purchase a SIM Card and set up a service agreement with a network provider. Make sure that the network provider selected has good coverage in the proposed area. In general it is better to select a 900MHz system because the coverage is more widespread and the modem operates at a higher power level.
Wire Line Option
VersaNet2 will work with many of the commonly available wire-line modems, however, because of the vast number of variations in specification and settings, RDT have standardised on the Westermo TD-32. This modem is a rugged industrial design offering all the facilities required for either dial-up or leased line
operation.
Specification
The TD-32 is available in two standard versions for power supply by either 230V AC or 12 - 36V DC.
A watchdog facility continually monitors the power supply and internal hardware as well as the operational software. In the event of a problem the modem automatically resets. This feature has been included to make the unit more suitable for use in unmanned
locations.
Leased line connections can be made on 2 or 4 wires. The modem can also be used on ordinary twisted pair cables to provide long distance asynchronous communications.
