Siemens 6ES7522-1BP00-0AA0 DQ 64x24VDC/0.3A BA

High-density sinking digital outputs arranged in four 16-channel groups for SIMATIC automation systems.

Product Overview

Siemens 6ES7522-1BP00-0AA0 is a SIMATIC S7-1500 SM 522 basic digital output module designated DQ 64x24VDC/0.3A BA. It provides 64 sinking 24 V DC outputs organized in groups of 16, enabling a compact output density within a 35 mm module width. Siemens specifies 2 A per group at 60 °C and identifies cables and terminal blocks as separately ordered accessories. The module is intended for S7-1500 and ET 200MP installations that require numerous controlled field-output points. Before replacement, compare the complete order number, channel assignment, group loading, terminal arrangement and engineering configuration with the installed equipment.
