VersaNet Wireless Telemetry
VersaNet is a wireless telemetry and remote alarm & control system, that allows the wireless interconnection of two or more pieces of equipment needing to exchange data in one of the standard process control data formats, such as, 0-5v, 0-20mA, volt-free contact, relay output, pulse counting or RS232 MODBUS format. The system is modular and hence very flexible, allowing nodes to be constructed with minimum I/O (1 digital and 1 pulse) up to maximum capacity of 128 each, digital, pulse and analogue.
The flexibility also permits the construction of simple point-to-point links or large complex networks with some nodes acting as repeaters to extend the coverage range. Communication is usually via the RDT UHF radio but the system can also utilise GSM or wire-line modems, either as the main link or as back-up to the radio.
Features
- Modular design, can be configured for most applications
- Fully user programmable/configurable allowing any given input to be sent to any given output anywhere within the VersaNet network
- Transmissions instigated on time interval, change in signal status or combination of both for all given signal types
- Every transmission is error checked and acknowledged
- Utilises listen before transmit strategy (UHF radio option)
- Programmable alarm delay period
- Low power operation with only 300µA current drain
- Compatible with industry standard MODBUS protocol commonly used within SCADA applications
- 12 bit analogue signal resolution as standard
- Any VersaNet2 node can act as a repeater permitting unlimited transmission range and easy avoidance of geographical obstructions. Each repeater node has I/O capabilities.
- Ability to switch a remote node to Transmit a signal for RSSI tests to assist with antenna alignment
- Utilises RDT's unique synthesised (multi-channel) RF transceiver module (optional)
- Options for GSM or Wire-line modems
- Allows SMS engineering messages (with GSM option)
- Comprehensive user manuals and configuration software
Applications
- Water & Waste: Flow control, Flow measurement, Solar powered outstations, Treatment monitoring, Level control, supply & distribution data
- Electricity: Rural automation, Hydro electric station, Fault monitoring, Remote data acquisition
- Production: PC & PLC comms, Distribution chains, Alarm management, Data logging, Process control, Central supervision
- Environmental & Building Management: Management information, Alarm monitoring/Access control, Flow measurement, Level measurement
- Gas & Oil: Flow control & measurement, Plant safety systems, Monitoring in hazardous zones
- Traffic & Transport: Traffic flow monitoring, Performance logging, Remote sign control, Mobile information, Ship to shore monitoring
Models
The VersaNet system is a modular construction consisting of a main controller card, incorporating the micro-processor and radio module (or interface to GSM) and a series of I/O cards. This allows a node to be constructed to meet virtually any I/O requirement.
Controller Card
The VersaNet IRDN334 communication controller card incorporates the UHF radio module and has on board I/O for a single digital or pulse, or optional analogue. It is fully compatible with the complete range of expansion cards allowing complex multi I/O nodes to be constructed.
Expansion Cards
There is a wide range of expansion I/O cards available to suit most applications. These range from digital, pulse and analogue input and output cards to combination cards and specialist low power options. All the cards connect to the controller via a simple ‘T-bus’ using a ribbon cable supplied.
UHF Antennas
RDT offer a range of antennas suitable for use with VersaNet, from a simple ½ Wave Whip that mounts directly on the unit, to a high performance Yagi for long range applications.
