Siemens 6ES7521-1BH10-0AA0 SIMATIC S7-1500 DI 16x24 V DC BA Input Module
A basic S7-1500 digital input module with sixteen 24 V DC channels, a typical 3.2 ms input delay and an included push-in front connector.
Technical Summary
PRODUCT CONTEXT6ES7521-1BH10-0AA0 is the Siemens SIMATIC S7-1500 DI 16x24 V DC BA signal module. Its sixteen channels are arranged as one group of sixteen and meet Type 3 input characteristics under IEC 61131.
Siemens publishes a typical input delay of 3.2 ms. The delivery includes the push-in front connector, so a quotation and replacement record should distinguish the complete module package from nearby S7-1500 input modules that require a separately ordered connector.

Compatibility
SELECTION BOUNDARIESRack and project
Confirm the S7-1500 station slot and TIA Portal hardware catalog support.
Field supply
Check 24 V DC source, commons, group protection and conductor arrangement.
Module selection
Do not substitute the 32-channel or HF execution solely because the enclosure is similar.
Replacement
