About the Siemens 6ES7431-0HH00-0AB0
The Siemens 6ES7431-0HH00-0AB0 is the 16-channel non-isolated SM 431: twice the channels of the 8-channel 6ES7431-1KF00-0AB0, at the same 13-bit resolution. Siemens's data sheet gives voltage and current ranges of ±1 V, ±10 V, 1 to 5 V, ±20 mA and 4 to 20 mA, a 24 V DC load supply for 2-wire transmitters, and 2 W typical power loss. SiePortal shows its phase-out announced on 1 October 2025 and its product cancellation on 1 October 2026.
What is the 6ES7431-0HH00-0AB0 used for?
It reads many transmitter signals into an S7-400 CPU where the signals share a common reference.
Lifecycle and successor
Discontinued.
