Siemens 6ES7 522-5FH00-0AB0 Digital Output Module

Siemens 6ES7 522-5FH00-0AB0 Simatic S7-1500 Digital Output Module is a 16-channel digital output block for SIMATIC S7-1500 controllers. In Siemens documentation it is described as DQ 16x230VAC/1A ST, indicating 16 outputs suitable for switching 230 V AC loads at up to 1 A per channel. The module connects to the S7-1500 I/O system and communicates with the CPU through the standard backplane, enabling synchronized control of external devices from the PLC program. Common applications include driving relays, contactors, and other AC-powered actuators in automation tasks such as machine control, packaging lines, and process automation. Designed to integrate with Siemens engineering environments, it supports diagnostics and configuration via the TIA Portal and is part of the SIMATIC SM 522 digital output family.
