ABB 07KT97 GJR5253000R4270 Programmable Logic Controller Basic Unit

The ABB 07KT97 GJR5253000R4270 Programmable Logic Controller Basic Unit is a 90-series central processing unit of the ABB Advant Controller 31 (AC31) PLC family. As the CPU basic unit, it executes the application program, arbitrates the I/O bus and acts as the communication gateway for the controller station, with serial and CS31 communication interfaces (an Ethernet port is stated per the listing title). Multiple variants of the 07KT97 exist (e.g. 07KT97D, 07KT97F1) for different I/O and communication configurations.
