Sixteen-channel basic voltage acquisition for SIMATIC S7-1500 automation systems.
Siemens identifies 6ES7531-7LH00-0AB0 as the SIMATIC S7-1500 AI 16xU BA analog input module. It provides sixteen voltage input channels in one group, 16-bit resolution, diagnostics and hardware interrupts.
The module is designed for basic voltage measurement in an S7-1500 station. Its front connector must be ordered separately, and engineering compatibility must be checked against the CPU, TIA Portal or STEP 7 environment, configured input range and field wiring.
