Siemens 6ES7522-5HH00-0AB0 Simatic PLC Module

Siemens 6ES7522-5HH00-0AB0 is a SIMATIC S7-1500 digital output module that provides 16 relay outputs at 230 V AC with a 2 A per-channel rating, organized in groups of two channels (four groups total) that offer 4 A per group. This module is designed for integration into the SIMATIC S7-1500 system and supports diagnostics and a switching cycle counter for the integrated relays. It also offers safety features for industrial automation, including safety-oriented shutdown of load groups up to SIL1 in accordance with EN IEC 62061:2021 and Category 2 / PL c per EN ISO 13849-1:2015. Front connectors for field wiring (screw terminals or push-in) are ordered separately, allowing you to tailor the wiring interface to your installation. In use, the DQ 16x230V AC/2A ST Relay module expands the S7-1500 I/O to drive relays and other 230 V AC loads within a PLC control scheme, enabling scalable, backplane-backed I/O expansion in automation environments.
