Siemens 6ES7522-1BP00-0AA0 SIMATIC S7-1500 DQ 64x24VDC/0.3A BA Digital Output Module

The Siemens SIMATIC S7-1500 DQ 64x24VDC/0.3A BA (6ES7522-1BP00-0AA0) is a 64-channel digital output module rated 24V DC / 0.3A per output, grouped in 16 channels with 2A per group at 60°C. It supports safety-related shutdown of load groups up to SIL2 per IEC 62061:2021 and PL d / Category 3 per ISO 13849-1:2015, and mounts in a 35 mm wide housing in the S7-1500 rack.

Technical Specifications

Selection Notes

The BA suffix marks this as the basic variant, with diagnostics limited to the module's RUN/ERROR LEDs — per-channel status display requires a SIMATIC TOP connect connection module. The SIL2 / PL d / Cat. 3 safety rating applies to shutting down an entire 16-channel load group, not individual-channel diagnostics, so it fits designs where a group of outputs needs a certified emergency-stop path without a separate safety I/O module. Size connected loads against the 2 A group limit, not just the 0.3 A per-channel rating — 16 channels loaded at 0.3 A each would exceed the group ceiling.

Applications

Drives 24V DC loads such as solenoid valves, contactor coils, and indicator lamps from an S7-1500 rack, including machine zones where a load group must be safely de-energized to SIL2 / PL d without a dedicated safety I/O module. Cables and TOP connect connection modules are ordered separately.
