RFScada 4ADI-5DO2 units provide a high reliability, long range, bi-directional wireless
transmission/reception
A
system comprises 1 to 255 RFScada units, and simple configuration at
the factory or in
the field allows every output on every unit to be driven from any input on any
unit, for maximum flexibility. Modbus capability, at every unit, is also
standard for additional control and monitoring options. The RFScada system has
many applications in the SCADA, oil, gas, water, security and other industrial
fields.
The RFScada units are designed for high reliability applications such as
oilfield tanks,
pumps, lift stations, wells, access control & monitoring. They provide a very
cost effective, alternative solution to overhead cables or digging trenches when
connecting to Unlike competing models the RFScada devices maintain continuous, encrypted bi-directional communications, for positive verification of correct operation in all units; plus immediate indication of control & monitoring status at every unit. No more guesswork, unknowns or failures caused by ‘report on exception’ and ‘one way transmit’ type units, which often give no indication in the case of a failure. Some of the many features include....... ¨ Up to 252 digital inputs, 252 relay outputs, 252 analog inputs and 248 analog outputs per system. May be configured to route any input to any output. ¨ Quickly and easily add wireless I/O to existing systems; compatible with virtually all SCADA systems, with analog, digital and computer interfacing. Easily expandable in the field to meet future requirements. ¨ High reliability industrial grade, wide temperature range components. ¨ Fully bi-directional and continuous signal exchange ensures each unit is capable of controlling, monitoring and verifying signals at all other units – continuous, positive verification of correct operation. ¨ Out of the box ‘Plug and Play’ operation, pre-configured for your application. Duplicate remote relays, switches and analog signals without inter-connecting ‘wires’. ¨ The 4ADI-5DO, 4ADI-5DO2, 8ADI-9DO & 16ADI-9D2AO all communicate; mix which ever units you need to build up a complete system. ¨ Any unit may be a repeater, multiple repeater branches and levels may be configured for applications such as pipelines. ¨ All units revert to a known state upon failure or communication loss, either local or remote within seconds. ¨ Custom surface mount design increases reliability, saves size and cost ¨ Modbus configuration, monitoring and control built in. RS-232 and RS-485 interfaces standard. ¨ LED and additional relay output indicates the system state and verified communication status. ¨ Dual power supply standard (115 Volts AC or 10 to 28 Volts DC). ¨ Very long range, non line of sight capabilities with several radio options available. ¨ Completely prepackaged solution in a corrosion resistant, NEMA 12 enclosure ready to be installed; requires just power and signal connection for operation. Most applications will not require an external antenna. ¨ Spread spectrum ISM version uses the 900MHz band at 1 Watt of power, the legal limit ion the USA. This provides much greater range and vastly improved interference rejection than the short range, congested 2.4GHz consumer band. ¨ 1, 2 and 5 Watt VHF and UHF versions available for extreme range, non line of sight applications. ¨ Spread spectrum ISM versions require no license for ownership or operation in the USA. Fully FCC approved. ¨ VHF and UHF versions require an FCC license; we can assist with obtaining a license. ¨ Highest data integrity with encrypted, secure error rejecting data communication methods to prevent false signals. ¨ LED’s indicate every input contact state, every output relay state, RF transmit, RF receive and system / Modbus activity. ¨ Built in control routines for common applications often eliminates the need for additional control logic, PLC or computer. ¨ Approximately half the cost of the closest competitive units; often cheaper than wire!
