Inline terminals with “2 MBD” added to their item designation work with a transmission speed of 2 Mbps. These terminal blocks are discontinued or no longer in the range. If you require this transmission speed, please ask your local Phoenix Contact representative. If you can work with a transmission speed of 500 kbps, select as a replacement the corresponding variant that does not have “2MBD” added to its item designation. Please note that a uniform transmission speed must always be used within one inline station. The terminal is designed for use within an Inline station. It provides a 24 V supply voltage to the main circuit (UM) and automatically supplies power for the 24 V segment circuit (US). The terminal has protection against polarity reversal and surge voltage. The internal fuse protects the main and segment circuits. This terminal has an LED for bus diagnostics. It occupies two input data bits, which indicate the availability of the supply voltage and the status of the fuse.
