Mini SCADA I/O Module

RFI  MSIO/1 Low Cost Radio Interface Module
      Analog & Digital - 8 inputs - 8 outputs - expandable

New generation expandable I/O system suitable for radio environments. Directly
compatible with RFI series radio modems and can accept DC power inputs from
nominal +12V to +48VDC negative ground.

Features
• Economical
• High Speed RS-232 port
• Expandable in groups of 8 I/0
• Standard 0-5V analog or 4-20mA
• Suitable for Analog and Digital data
• 8 Inputs - select as Digital or Analog
• 8 Outputs - select as Digital or Analog
• Powerful low cost point to point system
• Watchdog timer for Link fail indication
• PLC master for point o multipoint system
• Programmable I/O for SCADA applications
• Status LED’s for fast operational diagnostics
• Conditions input DC volts for Radio Operation
• Can be installed and commissioned without test equipment

Applications
Point to Multipoint Data Acquisition and Control
The MSIO/1 is an ideal low cost solution to SCADA requirements. Each input can be configured as an analog or
digital. Any terminal program can be used to change parameters. A simple ribbon cable connects the MSIO/1
devices to a RFI series radio modems, and DC for both units is supplied via the MSIO/1. Standard input DC is a
nominal +12V, however a built in DC/DC converter enables +24 and +48V DC supplies to be used.
General PLC Applications
The MSIO/1 provides a low cost alternative to remote PLC slave units. If a PLC is used at the master station, the
MSIO/1’s can be used as slaves for a point to multipoint SCADA system. This system is useful for general
switching, return status indicators and general-purpose SCADA applications, with or without a PLC Master.
Digital I/O Analogs and expansion
Digital and Analog I/O in addition to the standard RS232 serial port, are provided in the RFI MSIO/1. Expansion
options allow the user to configure large SCADA capability by the addition of extra MSIO/1 modules. Special
options are available for high scanning speed applications. For more details regarding interface parameters,
contact the manufacturer.
