The Siemens 6ES72121HG500XB0 is a current-production CPU 1212C with relay outputs and an Ethernet interface, DIN-rail mount, 24 V DC supply.
DIN rail clip, 24 V DC input. Relay outputs are dry contacts—no sequencing needed with the load side. Ethernet autosenses, so no crossover cable required. For a quick panel swap, pull the old CPU, snap this one on, re-terminate the 24V and relay commons. No shop, no crane, let's go.
The alternate order code 6ES7212-1HG50-0XB0 is functionally identical; it drops into the same panel without rewiring.
The output type is relay output, providing galvanic isolation for switching field loads.
It has an Ethernet interface for programming and communication, but it is not a Profinet IO controller or device.
Yes, the two order codes are functionally identical — same footprint, wiring, and relay outputs. No rewiring needed.
