RFScada32

The RFScada32 is in stock and shipping now!

The RFScada32 is a 4G (fourth-generation) device that features a high-performance, high-integration general purpose remote terminal unit (RTU) with on-board datalogger. The unit is capable of acquiring data from virtually any third-party device that supports analog, digital, pulse or Modbus connection (hard-wired or wireless). Acquired data can be stored using removable data cards, and transmitted to other remote drives using the Modbus and RFScada protocols.


On-board or remote displays allow for easily readable data display and control entry for all acquired signals.

The RFScada32 may be configured using these methods:

  • Using the keypad and liquid crystal display (LCD) screen.
  • Using a PC locally (via built in USB, RS-232, or RS-485 ports, all of which are optically isolated).
  • Using a PC remotely (using a serial link or radio connection, or using the SD card interface to store or load configurations).

The RFScada32 features a built-in interface to accommodate a 1-Watt, 900 MHz spread spectrum radio module. The unit may also use any commercial radio modem connected via a second set of RS-232 and RS-485 ports, both of which are optically isolated. A third RS-485 port is available for general purpose use, but it typically used for a touch-screen flat-panel display. A fourth high-speed port is integrated, allowing direct, wired communication to RFSCADA 4G peripherals, like the 24-relay output board. All analog signals are acquired, processed and output at a minimum resolution of 16 bits, and Modbus supports acquiring 32-bit resolution data from other devices. There are 32 inputs on the board, each can be configured as Analog 4-20mA, 0-10VDC, 0 to 5VDC, digital (dry contact/switch), or pulse. The eight 4-20mA analog outputs are driven by any local or remote signal source. The flexible scaling scheme covers virtually any field application. Nine relays on the board may be controlled by any other source.

Consider this - Tank control with adjustable hysteresis or oilfield pumps dependent of well pressure can be controlled and easily configured. An optional relay board adds another 24 relays, all of which may be configured in a similar way.

Features

  • Thousands of digital inputs, relay outputs, analog inputs, pulse inputs and analog outputs per system. This means you can easily field configure the unit to route any input to any output.
  • Quickly and easily add wireless I/O to existing systems. The 32 is compatible with virtually all SCADA systems, with analog, digital and computer interfacing. The unit is easily expandable in the field to meet future requirements and upgrades.
  • Eight analog outputs are standard, but more may be added.
  • High-reliability and industrial-grade with 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, preconfigured to your application and needs. Duplicate remote relays, switches and analog signals without interconnecting wires.
  • The 4ADI-5DO3, 8ADI-9DO, 16ADI-9D2AO, and 32 can all communicate. Mix the Data Delivery Device units you need to build a complete system.
  • Any unit can be a repeater. Multiple repeater branches and levels may be configured for applications such as pipelines.
  • All units revert to known state upon failure or communication loss – either local or remote – within seconds.
  • Easy-to-use custom surface-mount design increases reliability, flexibility, cost and saves space.
  • Modbus configuration, monitoring and control is integrated. RS-232 and RS-485 interfaces are 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).
  • Range of up to 40 miles with an external antenna. Up to 7 miles of range with standard, enclosed antenna. Non-line-of-sight capabilities with several radio options are available.
  • Completely pre-packaged solution in a corrosion-resistant NEMA 12 enclosure that is ready to be installed. Installation requires power and signal connection for operation. Most applications will not require an external antenna.
  • Spread-spectrum ISM version uses the 900MHz band. This provides much greater range and vastly improved interference rejection than the short-range, congested 2.4GHz consumer band.
  • Spread-spectrum ISM versions require no license of ownership or operation in the United States. Fully FCC approved.
  • 2- and 5-Watt VHF and UHF versions available for extreme range, non-line-of-sight applications.
  • VHF and UHF versions require an FCC license. Let Data Delivery Devices 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.
  • Integrated control routines for common applications often eliminate the need for additional control logic, PLC or computer.
  • Approximately half the cost of the closest competitive units, and often cheaper than wire.
