S7-1500 DQ 8×24 V DC/2A HF (6ES7522-1BF00-0AB0). Siemens describes it as: digital output module DQ 8×24 V DC/2A HF; 8 channels in groups of 8; 8 A per group; diagnostics; substitute value: 2 channels can be used for pulse width modulation(PWM) . the module supports the safety-oriented shutdown of load groups up to SIL2 according to EN IEC 62061:2021 and Category 3 / PL d .
The front connector (screw or push-in, 40-pole for 35 mm modules) is ordered separately and stays wired when the module is replaced.
See our SIMATIC S7-1500 range and the Siemens order number guide (Arabic).

Typical applications
- ET 200MP distributed I/O stations
- Central I/O for S7-1500 controllers
- Replacing a failed module of the same order number
Compatibility and replacement
The front connector is not included: order 6ES7592-1AM00-0XB0 (screw) or 6ES7592-1BM00-0XB0 (push-in) for 35 mm modules, or the 25 mm connector for 25 mm modules.
Before you replace it
- Back up the program and parameters from the old device if it still runs.
- Check the supply voltage and wiring of the old unit before installing the new one.
- Look for signs of overvoltage, water or heat damage in the cabinet so the new part does not fail for the same reason.
Frequently asked questions
Is the front connector included?
No, it is ordered separately (screw or push-in type).
Does it work in ET 200MP?
S7-1500 I/O modules marked S7-1500/ET 200MP can also be used in ET 200MP stations.
