Siemens 6ES7522-1BL10-0AA0 SIMATIC S7-1500 DQ 32x24VDC/0.5A BA 32-Channel Digital Output Module

The Siemens 6ES7522-1BL10-0AA0 is a SIMATIC S7-1500 digital output module, type DQ32x24VDC/0.5A BA, with 32 transistor outputs in groups of 8, each channel rated 0.5 A and each group 4 A. It supports safety-oriented shutdown of load groups up to SIL2 per IEC 62061 and Category 3/PL d per ISO 13849-1.

Technical Specifications

Selection Notes

The 0.5 A per-channel rating and 4 A per-group ceiling put this module in the standard-duty class for S7-1500 digital output boards, sized for relay coils, contactor pilot circuits, and indicator loads rather than direct motor or high-current actuator switching. The SIL 2 / PL d safety-related tripping capability (module FS02 and higher) lets a standard I/O module take part in a safety shutdown path, which removes the need for a separate fail-safe output module in installations that only require category 3 performance level d. Choose a fail-safe F-DQ module instead when the application needs SIL 3 or a fully certified safety channel rather than safety-related tripping of a standard module.

Applications

Drives relay coils, contactor pilot circuits, solenoid valves, and status indicators in S7-1500-based machine and process control panels, including applications where the output group also needs a SIL 2 / PL d shutdown path.
