Siemens 6ES7522-1BF00-0AB0 Digital Output Module

Siemens 6ES7522-1BF00-0AB0 is an 8-channel digital output module designed for the SIMATIC S7-1500 family, delivering 24 V DC switching with a maximum current of 2 A per output to drive loads such as indicators, actuators, or small relays in automated systems. Listed as DQ 8x24 V DC/2A HF, the module groups eight outputs in a single bank with an 8 A per-group rating, and its high-frequency (HF) capability supports rapid switching and precise timing for applications requiring tight control loops. Two channels can be configured for PWM, enabling controlled duty cycles for DC actuators, while built-in diagnostics monitor output state, fault conditions such as short circuits or overcurrent, and the module supports safety-oriented shutdown of load groups up to SIL2 according to EN IEC 62061:2021 and Category 3 / PL d per EN ISO 13849-1:2015. Front connectors are available as screw-terminal or push-in variants, ordered separately, and the DQ module is intended to expand digital output capacity within SIMATIC S7-1500 projects, integrating with the system's I/O architecture.
