About the Siemens 6ES7334-0KE00-0AB0
The Siemens 6ES7334-0KE00-0AB0 is the SM 334 combined analog module with four inputs and two outputs at 12 bits. Siemens describes it for 0-10 V, Pt100 in the climatic range and a 10 kΩ measuring range, isolated, with a 20-pin front connector. Siemens's data sheet marks it as a spare part. Siemens names no direct successor for the order number; its route forward is migration to the S7-1500 with ET 200MP.
What is the 6ES7334-0KE00-0AB0 used for?
It suits building services and small process control, where a few temperatures are read and a few 0-10 V set-points are sent from one slot.
Lifecycle and successor
Discontinued: product cancellation (Siemens SiePortal), spare part only.
Before you order
What to photograph or confirm so the right unit is quoted.
Check the order number on the module. The front connector with the field wiring normally moves across to the replacement.
