The IDM50b is a Frequency Shift Keyed (FSK) or Quadrature Amplitude Modulation (QAM) programmable modem for SCADA / Power-Line communication, supporting communication standards such as ITU V.21, V.23, R.35, R.37, R.38A, R.38B, V.29, Bell 103 and Bell 202. |

PRM4 modems can be used to establish a transparent RS-232 / RS-485 / RS-422 link, as if a physical cable had been laid between the two points where the modems are installed. The modems operate in the free 868MHz band, and have a range of between 2 and 16km between two modems (depending on the type of antenna used), with the option to extend the range even further using additional modems set to "repeater" mode. |

The Galvanically Isolated RS485 / RS422 Repeater does just what it's name says - it can be used to extend RS485 / RS422 networks, galvanically isolate them (up to 1500V DC), or both. |

The SCM201 measures AC current in the 0-5A range and converts it into a 4-20mA Current Loop signal. The unit also features galvanic isolation on both the input and output sides, and test points for monitoring the current loop without interrupting it. |

The SCM202 measures AC voltage in the 0-500V range and converts it into a 4-20mA Current Loop signal. The unit also features galvanic isolation on both the input and output sides, and test points for monitoring the current loop without interrupting it. |

The SCM203 is used to add galvanic isolation to a 4-20mA current loop signal. It also generates a 40-200mV signal for convenient monitoring of the current loop. The unit requires no external power supply, as it is powered from the current loop itself. |

Industrial devices which implement a serial interface (RS232/RS485) can be connected to a modern Ethernet/LAN network via the NetX Serial to Ethernet converter. The unit is set up via a web-browser interface. |

RPB868s are used in pairs, with each unit having 4 inputs and 4 outputs: the inputs from one unit are wirelessly copied to the outputs of the other unit, and vice versa. The units are used to replace simple on/off cables where it is either impossible, inconvenient or impractical to lay them. For example, an on/off switch in one location could be used to control power to a device in another location, without the need to run physical wires between the two locations. The units have a range of 2-16km (depending on the type of antenna used). |
