Description
Siemens 6ES7522-1BH00-0AB0 SIMATIC S7-1500 DQ16 Digital Output Module 24VDC 0.5A
The Siemens 6ES7522-1BH00-0AB0 is a 16-channel digital output module for the SIMATIC S7-1500 programmable logic controller platform. Designated DQ16x24VDC/0.5A HF, it provides 16 individually controlled 24V DC transistor outputs arranged in two groups of 8, with single-channel diagnostics and support for safety-oriented load group shutdown up to SIL2. Manufactured in Germany in 2015.

Applications
The SIMATIC S7-1500 series is Siemens' current-generation mid-to-high-end PLC platform, introduced around 2012 as the successor to the S7-300 and S7-400 families. It is widely used in manufacturing automation, process control, machine building, and infrastructure applications worldwide. Digital output modules like this DQ16 are used to switch field devices — solenoid valves, contactors, indicator lights, relays, and small actuators — directly from the PLC's control logic. The HF (High Feature) designation on this module means it includes per-channel diagnostics, allowing the controller to detect wire breaks or short circuits on individual output channels without halting the entire group, which is valuable in applications requiring high availability. The integrated safety shutdown capability (SIL2 / PL d) makes this module suitable for use in safety-related control applications, particularly where load groups must be de-energized reliably in a fault or emergency condition. This type of module is a current, actively deployed component in S7-1500 systems across automotive, food and beverage, pharmaceutical, and general industrial automation installations.
This Siemens 6ES7522-1BH00-0AB0 SIMATIC S7-1500 DQ16 digital output module was pulled from a large PLC control cabinet that was decommissioned from active service. It was in use and functional at the time of removal. The module has been inspected and is in good used condition. The housing is intact with no cracks or broken clips; the front terminal rows and backplane bus connector show normal handling wear consistent with installed use. Note that the front connector (field wiring plug) is not included — module only. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
