The SCADASwitch is a datacom interface device for SCADA & industrial control applications where Modbus Multiplexing, RS232 Switching, RS485 Conversion and/or Radio Keying is required.

The SCADASwitch has two RS232 input ports and a RS232/RS485 output. With low power draw, small size, DIN rail mounting, and Class I Div 2 rating it is ideal for use in remote EFM/RTU applications.

• ●  Two RS232 Input (1 DB9)
• ●  Simultaneous RS232 & RS485 (2/4 Wire) Output
• ●  1200BPS – 115KBPS Baud
• ●  10-30VDC Operation
• ●  Low Current Draw – 6ma @ 12VDC
• ●  Class I Div 2
• ●  -40 to 70 C Operation
• ●  DIN Rail Mount
• ●  Configuration via RS232 Terminal

Applications:

• ●  PLC, RTU, EFM, Power Meter, Data Logger
• ●  Pipeline SCADA
• ●  Oil & Gas RTU/EFM SCADA

Modbus Multiplexing Mode
Allows 2 SCADA Hosts to share single port of a RTU/EFM device. Works for other requests / response protocols (ie. Modbus, Fisher ROC).





RS232 Switch Mode
Allows a configuration computer to connect to an RTU/EFM device without the need to disconnect the SCADA Host.





Modbus Address Translation
Translates Modbus address on Input Port to a different address on Output Port. This feature is useful when the same RTU exists on 2 different SCADA networks and is addressed with different Modbus address on each network.





Modbus Register Write Blocking
Prevent Modbus Writes to PLC/RTU/EFM on a specific Input Port. This feature can be used to grant Read-Only access to a third party SCADA host.





RS232 Radio Keying
Allows an RTU with nohandshaking signals to key a radio.





RS485 Conversion
Converts RS-232 to RS-485.





Custom Protocol Conversion
Upon special request, Bentek Systems can develop custom protocol conversion firmware for SCADASwitch (ie. to enable Modbus protocol for specialized devices)
