Siemens 6ES7231-7PD22-0XA0 is an Analog input Module for the Simatic S7 product family.
From a maintenance perspective, digital input hardware creates the path from field-level status signals to control logic, allowing the system to evaluate operating conditions and respond through configured sequences or protective actions. The original wiring and configuration records should guide application.
Within an S7 installation, the exact hardware order number determines supported interfaces and configuration behavior. System and software compatibility should be checked before replacement. The installed revision should be confirmed before the product is applied.
Country of origin is listed as China.
When this product is used for lifecycle support, technicians should confirm the installed revision, connection arrangement, and system assignment rather than assuming interchangeability with a similarly named module. Configuration records should be reconciled with the exact installed assembly.
SIEMENS SIMATIC S7-200 analog input EM 231, only for S7-22X CPU, 4 AI, +/-80 MV a. thermocouples Type J, K, S, T, R, E, N; 15 bit+sign
