Siemens SIMATIC S7-1500 digitaalilähtömoduuli DQ 16x24VDC/0.5A (6ES7522-1BH10-0AA0)

Machine builders and system integrators often face the challenge of wiring and diagnosing discrete outputs in compact control cabinets. The Siemens SIMATIC S7-1500 DQ 16x24VDC/0.5A module solves this by providing 16 sourcing (PNP) digital outputs in a single, DIN-rail-mountable unit. With push-in front connectors and per-channel diagnostics, it streamlines installation and troubleshooting in packaging lines, material handling systems, and general automation tasks.

Key specifications

• 16 digital outputs, sourcing (PNP), grouped in fours
• Output voltage: 24 V DC; current per channel: 0.5 A
• Short-circuit and overload protection per channel
• Channel-level diagnostics: wire break, short circuit, supply voltage
• Isolation between groups and to backplane bus
• Push-in front connector included
• DIN rail mounting, 35 mm profile
• Operating temperature: 0 to 60 °C
• Configuration via TIA Portal; firmware update capable

Why choose it

This module offers robust protection and diagnostics that reduce downtime. The push-in terminals cut wiring time significantly, and the per-channel isolation enhances system reliability. As part of the S7-1500 family, it integrates seamlessly with TIA Portal for unified engineering.

Ideal use cases

• Controlling solenoid valves, contactors, and indicator lamps
• High-speed output tasks in packaging and assembly lines
• Applications requiring detailed diagnostics for predictive maintenance
• Retrofitting existing S7-1500 stations with additional digital outputs

Good to know

The module's maximum power loss is 2.5 W, and it supports firmware updates for future enhancements. The front connector is included, simplifying initial setup and replacement.
