Serial Converter and Repeaters

Most industrial computer systems come with standard RS-232 serial ports. Though widely accepted, RS-232 has limited transmission speed, range and networking capabilities. The RS-422/485 standards overcome these limitations by using differential voltage lines for data and control signals. The Serial Media Converters provide conversion between serial networks and other media. They can transparently convert RS-232 signals to RS-422/485 signals, as well as wireless and fiber optic signals.

RS-422/485 Repeaters

Most industrial computer systems come with standard RS-232 serial ports. Though widely accepted, RS-232 has limited transmission speed, range and networking capabilities. The RS-422/485 standards overcome these limitations by using differential voltage lines for data and control signals. The RS-422/485 repeater simply amplifies, or boosts, existing RS-422/485 signals to enable them to cover longer distances. It extends the communication distance by 1200m (4,000 ft.) or increases the maximum number of connected nodes by 32.

RS-232/422/485 Converters

The serial media converters provide conversion between serial networks and other media. They can transparently convert RS-232 signals to RS-422/485 signals, as well as convert RS-422/485 to RS-232 signals without changing the PC's hardware or software. The converter lets you easily build an industrial grade, long distance communication system with standard PC hardware.

RS-232/422/485 to Fiber Optic Converters

Fiber optic transmission offers the benefits of wide bandwidth, immunity to EMI/RFI interference, and secured data transmission. The fiber-optic converter is used as an RS-232/422/485 point-to-point or point-to-multipoint connection for transmitting and converting full/half-duplex signals and their equivalents within a fiber optics environment. Fiber optics is the perfect solution for applications where the transmission medium must be protected from electrical exposure, lightning, atmospheric conditions or chemical corrosion.

  • Siemens
Siemens offers a wide range of Programmable Logic Controllers (PLC). S7-1200 PLC is suitable for small individual machine applications, whereas S7-300 PLC was previously targeted towards medium to high demand applications. However since it is nearing its end-of-lifecycle, S7-300/400 PLC series have been supplemented with the innovative S7-1500 PLC series. A new range of HMI panels are also available in all sizes for suitable operator control/monitoring. S7-1200 and S7-1500 are both part of Totally Integrated Automation (TIA) platform and programmable via Siemens TIA Portal software.
