- Sixteen voltage or current input channels
- Thirteen-bit conversion resolution
- Two-wire transmitter supply through 24 V L+
6ES7431-0HH00-0AB0 is a non-isolated SM 431 analog input module for Siemens SIMATIC S7-400 systems.
Its sixteen channels acquire configured voltage or current signals, including 4 to 20 mA transmitter loops, with 13-bit resolution.
Correct application depends on the selected range, field wiring, L+ transmitter load, common-mode limits, shielding, addresses, and conversion timing.
