What It Is and Where It Fits
The Siemens 6ES7922-5BD00-0CG0 is a migration cable that connects MTA TC (Multi-Thermocouple Terminal Assembly) field wiring to an ET200SP HA analog input module — specifically the AI 16xTC/8xRTD 2-/3-/4-wire HART variant. It carries 23 conductors of AWG 26 over a 3-meter length, which is the right reach for routing from the marshalling cabinet to the I/O rack in a typical HA (High Availability) system layout.
