6ES7523-1BL00-0AA0

S7-1500 SM 523 Digital Input/Output Module

Officially documented Siemens Combined digital input/output module. Combines discrete sensing and actuation in a single S7-1500 signal module. It is useful where cabinet space is limited and a machine needs equal numbers of 24 V DC inputs and transistor outputs for sensors, valves, contactors, and status signals.

Applications

Product Application

Combines discrete sensing and actuation in a single S7-1500 signal module. It is useful where cabinet space is limited and a machine needs equal numbers of 24 V DC inputs and transistor outputs for sensors, valves, contactors, and status signals.

Capacity & Technology

Capacity and Technology

Sixteen 24 V DC inputs share one group and sixteen 24 V DC / 0.5 A outputs are arranged as two groups of eight. The module supports up to 4 A per output group and 8 A for the complete module, with a typical input delay of 3 to 4 ms.

Compatibility

System Compatibility

Use with a compatible SIMATIC S7-1500 rack and engineer in STEP 7 V13 or later. Verify load current, external 24 V supply sizing, group fusing, sensor type, output short-circuit conditions, front-connector wiring, and the required FS level for safety-related use.

Lifecycle

Product Lifecycle

Siemens identifies 6ES7523-1BL00-0AA0 as an active SM 523 product and includes the 40-pin push-in front connector. Current product data state SIL 2 / PL d Category 3 capability from FS03, so the functional status must be verified on the supplied hardware.

FAQ

1. How can buyers confirm that the quotation is for 6ES7523-1BL00-0AA0?

Match the complete order number 6ES7523-1BL00-0AA0 on the Siemens label, quotation and packing evidence. Also verify the documented product family, Combined digital input/output module, dimensions 25 x 147 x 129 mm and weight 280 g.

2. How can the condition of 6ES7523-1BL00-0AA0 be distinguished as new, used or refurbished?

Request current photographs of the housing, Siemens label, terminals or connectors, packaging and seals. For Combined digital input/output module, inspect for installation marks, terminal wear, changed labels, repaired housings or mixed packaging before accepting a New claim.

3. How should a supplier for 6ES7523-1BL00-0AA0 be checked?

Verify the supplier legal entity, business address, payment beneficiary, traceable quotation and written return terms. Ask for timestamped stock evidence showing 6ES7523-1BL00-0AA0 and compare the physical label with the official Siemens data.

4. Which engineering details must be checked before ordering 6ES7523-1BL00-0AA0?

Confirm the exact order suffix, 16 digital inputs and 16 digital outputs in one 25 mm module, supply and interface requirements, mounting space 25 x 147 x 129 mm, environmental limits and the configuration or BaseUnit requirements stated in the official documentation.

5. What physical evidence should be requested before payment for 6ES7523-1BL00-0AA0?

Ask for timestamped photographs and a short video showing the full Siemens label, model 6ES7523-1BL00-0AA0, serial or manufacturing data, packaging, connector area and the complete item. The evidence should be tied to the quotation reference.

6. Can a similar suffix replace 6ES7523-1BL00-0AA0?

Not automatically. Siemens suffixes can change channel count, electrical range, interface, BaseUnit, firmware, connector, performance or approval. Replacement requires a line-by-line comparison against the official data and the target system configuration.
