Siemens 6ES7522-5HH00-0AB0 16-Channel Output Module

Siemens 6ES7522-5HH00-0AB0 is a 16-channel digital output module (DQ 16x230VAC/2A ST Relay) designed for the SIMATIC S7-1500 system, delivering sixteen 230 V AC relay outputs with a per-channel rating of 2 A and a per-group rating of 4 A for two channels. This enables direct control of loads such as valves, actuators, or small motors in automation cells while preserving control cabinet space. The module includes diagnostics and a switching-cycle counter for the integrated relay to monitor wear and performance. A front connector (screw terminals or push-in) is ordered separately to match your wiring preference. For safety-critical configurations, the device supports load-group shutdown up to SIL1 per EN IEC 62061:2021 and Category 2/PL c per EN ISO 13849-1:2015, aligning with Siemens' safety-oriented design for S7-1500 I/O modules.
