What type of power supply is required for the Advantys STB network interface modules?
All the STB network interface modules (NIM) require an external 24 VDC power supply. This supplies convert the voltage to 5 VDC in order to provide the logic power supply to the I/O modules of the Advantys STB primary segment. This 5 V integrated logic power supplies deliver a maximum current of 1.2 A. This 1.2 A current can be increased by adding an STBCPS2111 auxiliary power supply module in each segment which also delivers a maximum current of 1.2 A. The logic power supply for the extension segments' I/O modules is provided by the BOS STBXBE1200 bus extension module placed at the head of these segments.
