The Model G303 RIO (Remote I/O) is a robust, economical solution for local I/O expansion, or Wireless and/or RS485 remote I/O requirements in SCADA and Process Control applications. 

In addition to its RS485 data port, it is available with an integrated spread-spectrum radio for high performance Wireless data communications.  And with the use of the integrated SS radio, the RS485 port can be used to add additional I/O or other Modbus devices to the Wireless system.  Other communication options are also available.

The G303 packs a powerful array of features not common in its price range.  Features include a Class I, Div 2 certification, rugged enclosure, very low power consumption, self-resetting fuses, LED annunciation, 24V transducer power source, precision A/D conversion, configurable meter input, flow rate and totalizer registers, industrial temperature rating, transient protection all the way around, 10 amp form C relay contacts, pluggable wire terminals, etc.  I/O includes 4 Analog Inputs, 1 Meter Input, 8 Digital Inputs and 4 Digital (relay) Outputs. See pdf data sheet (at left) for details, and call G3 Technologies for pricing.

The G303 is a very versatile unit, suitable for SOLAR powered applications, and a multitude of Wireless I/O applications.  It has all the I/O needed for most pump site or well-head automation.

The RioLink Wireless Modem is a stand-alone high performance Frequency Hopping Spread Spectrum (FHSS) radio with user selectable RS232 or RS485 data interface. It is available in 900MHz 100mW or 2.4GHz 50mW models, and in most applications it is plug-n-play. It is packaged in an attractive enclosure for panel or DIN rail mounting, and has connections for standard DB9 serial port cable, 10-30Vdc power input, and RPSMA antenna connector. It also has LEDs annunciating power and data activity, and is Class I, Div 2 certified.

In a typical G3 Wireless I/O point-to-point or point-to-multipoint network, the RioLink is used on the serial data port of the Modbus Master (RTU, PLC, Controller, PC). The RioLink is transparent to the serial data to & from the Modbus Master, and provides the radio link to the Wireless I/O Slaves.

A pair of RioLink modems can also be used to replace serial data cables with a wireless link between RS232 or RS485 devices that operates at 19.2K baud or less. Standard models are 9600 baud.

Depending on the RF range needed, the RioLink can be uses with a whip antenna right on the unit, or with a coaxial cable to an antenna mounted elsewhere.

This special version of the G303 is available as a drop-in replacement for the Amocams ASC 558 Combo RTU. It uses the same G303 hardware, but with an FSK Modem and custom firmware. Reference the G303-558 User Doc (below) for additional information.

The G303-558 was developed to help solve a major challenge faced when needing to expand or upgrade the aging Amocams systems. Because of the proprietary nature of the Amocams systems, along with un-availability of new equipment, the only solution was often a very expensive gross replacement of the entire SCADA system with something new.

With the G303-558 RIO serving as a drop-in replacement for the ASC 558 Combo RTU, the proprietary Amocams system can be expanded as needed, and the RTUs can be replaced one unit at a time (often within the operating budget) without disturbing the protocol supported by the Host PC.

At a later date, then, the HMI software can be updated with a modern standard, and the G303-558 RIO units can be easily converted to the standard Modbus version of the G303 RIO with your choice of data communications. This strategy provides a comfortable migration path to a SCADA system with modern open industry standards.

See the Amocams page for additional information about Amocams system support.

The Model G305 FSK Modem is a stand-alone unit that converts RS232 to an FSK Modem. This unit is used with an external radio that has audio Tx and Rx, and supports the use of VHF and UHF "splinter" frequencies.

The G305 is typically used at the computer (PC, PLC or RTU) that is polling RTU or RIO units in the field. It is packaged in an attractive enclosure for panel or DIN rail mounting, and has terminations for standard DB9 serial port cable, 12vdc power, audio and PTT signals for the external radio, and has LEDs for monitoring power and data activity.

The Model G301 RIO (Remote I/O) is a low cost solution for I/O expansion and remote I/O requirements in SCADA and Process Control applications.  It provides 24 Digital Inputs, 4 Analog Inputs, and 8 Digital (FET) Outputs.  See pdf data sheet for details, and call G3 Technologies for pricing.

The G301 uses standard RS485 serial data communications with Modbus Slave protocol.  It is especially suited for applications requiring low power and/or environmental tolerance, including SOLAR applications.  It also makes a great local or remote "Modbus End Device" to gather data for a PLC or RTU acting as a Data Concentrator.

The G301 board is also designed to install directly into a VAREC Series 1650 or 1750 Tank Gauge encoding head (or compatible unit) with direct connection to the Gray Code signal.  It also supports the additional analog and digital I/O requirements for a typical Tank Monitoring application.
