Siemens 6ES7522-1BF00-0AB0 SIMATIC S7-1500 DQ 8x24VDC/2A HF PLC I/O Module

The Siemens SIMATIC S7-1500 6ES7522-1BF00-0AB0 (DQ 8x24VDC/2A HF) is an 8-channel transistor digital output module rated 24 V DC at 2 A per channel, 8 A per group, with PWM output on up to 2 channels and short-circuit protection. It supports safety-related shutdown of load groups to SIL 2 / PL d (Category 3) when tripped by an F-CPU, and mounts in a 35 mm wide S7-1500 backplane slot.

Technical Specifications

Selection Notes

HF in the designation denotes the high-feature output module - the PWM function (2 channels, 2-100 ms cycle, 0.1% duty resolution) and the SIL 2 / PL d safety-related tripping support are features a standard (non-HF) 8x24VDC output module does not carry, so choose this variant specifically when a load needs PWM-controlled dimming or positioning, or when the output group must be safely shut down by an F-CPU. At 2 A per channel / 8 A per group, it suits DC solenoids, contactor coils, and small motor starters; group loads that together exceed 8 A need a second output group or a higher-current module.

Applications

Drives 24 V DC loads such as valve solenoids, indicator lamps, small DC motors, and contactor coils, including PWM-based dimming or positioning outputs and load groups requiring SIL 2 / PL d safety-related shutdown.
