ABB 1KGT031900R0001 - 520CMD01 R0001 CPU Communication Module

The ABB 1KGT031900R0001 is the order code for the 520CMD01 communication module (R0001, without battery-buffered real-time clock) in the ABB RTU520 product line, confirmed directly in ABB's product datasheet. The same datasheet lists R0002 (1KGT031900R0002) as the variant with a battery-buffered RTC. RTU520 module tables describe the 520CMD01 as the CPU module providing serial ports, an Ethernet port and a USB port, making it the central processing and communication card of the RTU520 assembly. Procurement documents from utilities list the same code for RTU spares. Input power, port counts and environmental ratings should be confirmed from the current datasheet revision before ordering.
