More about selecting S7-1500 digital inputs and outputs parts
SIEMENS SIMATIC S7-1500 combined digital modules
Combined DI/DQ modules integrate digital inputs and digital outputs into a single module. The PLC receives binary signals from sensors, push buttons or limit switches through the input channels and uses the output channels to control devices such as relays, contactors, indicators or valves.
The main advantage of a combined module is saving space in the PLC rack. It is particularly suitable when a machine requires a smaller or similar number of digital inputs and outputs and there is no need to use separate DI and DQ modules.
16 DI / 16 DQ
Combined module with 16 digital 24 V DC inputs and 16 digital 24 V DC outputs. Suitable for machines and equipment with a smaller number of binary signals.
32 DI / 32 DQ
A module with 32 digital inputs and 32 digital outputs provides a high signal density in one module and saves space in an S7-1500 configuration.
Sink / Source inputs
Selected versions support Sink / Source input wiring. When replacing a module, it is therefore important to check the wiring of the sensors and the original module.
24 V DC outputs
Digital outputs are used to control actuators such as relays, contactors, solenoid valves or signalling devices. Maximum output current is also an important parameter.
How to choose the right S7-1500 DI/DQ module?
When replacing an existing module, the safest method is to use the complete SIEMENS order number. When selecting another version, we recommend comparing in particular:
- number of DI digital inputs,
- number of DQ digital outputs,
- input and output voltage,
- maximum digital output current,
- Sink / Source wiring type,
- channel grouping,
- diagnostic and other module functions,
- compatibility with the hardware configuration in TIA Portal.
Typical S7-1500 digital input / output modules
| Order number | Module type | Basic configuration |
|---|---|---|
| 6ES7523-1BL00-0AA0 | DI 16x24 V DC / DQ 16x24 V DC/0.5 A BA | 16 digital inputs + 16 digital outputs |
| 6ES7523-1BP50-0AA0 | DI 32x24 V DC BA SNK/SRC / DQ 32x24 V DC/0.3 A SNK BA | 32 digital inputs + 32 digital outputs |
When should you use a combined DI/DQ module?
A combined module is particularly suitable when both digital inputs and outputs are required in the same part of the PLC system. A single module can connect sensors and push buttons while simultaneously controlling relays, contactors, valves or indicators.
If significantly more inputs than outputs, or vice versa, are required, separate DI and DQ modules may be more practical. When replacing an existing module, we recommend using its exact order number.
New and refurbished DI/DQ modules from stock
For current SIMATIC S7-1500 modules, we primarily check the availability of a new original SIEMENS part. We use an extensive European warehouse network with more than 900,000 industrial spare parts.
This also enables us to source refurbished, older, obsolete or hard-to-find modules. If you cannot find a specific order number in the e-shop, send it to us and we will prepare a quotation with price and delivery time.
Repairs of SIEMENS SIMATIC S7-1500 DI/DQ modules
If you have a faulty combined digital module, you can send it to us for diagnostics and repair. Repairs are carried out in specialised repair centres in Europe with which we have established long-term cooperation.
These repair centres specialise in industrial electronics and repaired modules are functionally tested before being returned to the customer.
Frequently asked questions
Yes. Ideally, send us the complete SIEMENS order number from the nameplate, for example 6ES7523-1BL00-0AA0, and the required quantity. We will prepare a quotation with price and delivery time, usually within 1 hour.
One module contains both digital inputs and digital outputs. It can therefore receive input signals from sensors and control output devices at the same time.
Not always. The number of DI and DQ channels, voltage, output current, Sink / Source wiring, module functions and hardware configuration in TIA Portal must be checked.
It depends on the application. A combined module saves space and is useful when a similar number of inputs and outputs is required. Separate modules may be more practical when significantly more inputs or outputs are needed.
Yes. You can send the faulty module to FOXON. We will arrange diagnostics, repair and subsequent functional testing at a specialised European repair centre with which we have long-term cooperation.
Yes. We also check other parts in European warehouses. Send us the complete order number and we will prepare a quotation based on current availability.

How to capture sporadic faults on Siemens S7 PLCs
Sporadic faults on Siemens SIMATIC S7 PLCs are difficult to find using standard online diagnostics. In this article, we show how auto.spy analyzer helps capture signals, events and video on a single timeline and trace the root cause of the problem afterwards.
