Siemens 6ES7523-1BP50-0AA0 SIMATIC S7-1500 DI 32x24VDC/DQ 32x24VDC/0.3A BA Digital I/O Module

The Siemens SIMATIC S7-1500 DI 32x24VDC/DQ 32x24VDC/0.3A BA (6ES7523-1BP50-0AA0) combines 32 digital inputs and 32 digital outputs rated 24V DC in one 35 mm wide module. Inputs follow IEC 61131 type 3 sourcing/sinking characteristics with a 3-4 ms delay, while outputs switch 0.3A per channel, 2A per group of 16, and require external fusing since they have no built-in short-circuit protection.

Selection Notes

Combining 32 DI with 32 DQ in one 35 mm slot saves rack space versus fitting a separate input and output module. The sourcing/sinking input stage accepts either PNP or NPN sensors without rewiring the group, which matters when field wiring standards vary between machine sections. Unlike output-only S7-1500 modules with internal short-circuit protection, this module's outputs are unprotected and need an external 4 A type B or C breaker per group — plan panel protection accordingly before commissioning.

Applications

Fits compact machine cells where sensor inputs and actuator outputs both need to sit in a single I/O slot — proximity sensors and limit switches on the input side, solenoid valves and pilot lamps on the output side. Cables and TOP connect connection modules are ordered separately.
