Siemens 6ES7522-1BL01-0AB0 SIMATIC S7-1500 DQ 32x24VDC/0.5A HF Digital Output Module

The Siemens 6ES7522-1BL01-0AB0 is a SIMATIC S7-1500 digital output module, DQ 32x24VDC/0.5A HF, with 32 transistor outputs in groups of 8, each group fused to 4 A. It supports safety-oriented shutdown of load groups up to SIL 2 per IEC 62061 and PL d, Category 3, per ISO 13849-1. Short-circuit protection is electronically clocked with a typical 1 A response threshold.

Technical Specifications

Selection Notes

This HF, high-feature, variant is the one to specify when downstream load groups need safety-related shutdown without a separate safety PLC or interposing relay: from HW functional status FS02 it supports safety-oriented tripping of standard modules up to SIL 2, PL d, Category 3. Each output group of 8 is fused to 4 A total, so grouping loads within that budget matters when sizing more than a couple of higher-current actuators per group. Choose a non-safety DQ module instead when the safety-related shutdown feature is not required.

Applications

Typical uses include driving 24 V DC solenoid valves, contactor coils, and indicator loads on S7-1500 machine controls where load groups must be shut down safely up to PL d / SIL 2, such as guard-interlocked actuator groups on packaging or material-handling equipment.
