Optimum power supply for the sophisticated automation solution with IO-Link communication interface
In the world of automation, ensuring a reliable and efficient power supply is crucial for the seamless operation of sensors, actuators, controllers, and HMIs. Balluff Heartbeat® power supply units with IO-Link interfaces stand out as an optimal solution for sophisticated automation systems, designed to meet the high demands of quality, longevity, and diagnostic capabilities.
Why Choose Balluff Heartbeat® Power Supply Units?

Balluff Heartbeat® power supplies are engineered with precision, incorporating high-quality components that guarantee an extended service life. These units are particularly well-suited for critical applications where reliability is non-negotiable. The built-in monitoring system is a standout feature, offering real-time insights into the power supply’s performance.
One of the most valuable aspects of these power supplies is the Heartbeat® status indicator LED. This feature provides a local, three-color indication of the current load situation, the device’s wear level, and the remaining service life. This visual feedback allows for immediate assessment of the system’s health. Additionally, the power supply’s digital outputs convey alarm, stress level, and lifetime information, enabling preemptive maintenance and avoiding unexpected downtime.
Enhanced Diagnostics with IO-Link Interface
The integration of IO-Link communication adds another layer of sophistication to the Balluff Heartbeat® power supplies. Through IO-Link, users can access detailed diagnostic and status information about the device, including operating parameters and historical data. This capability not only enhances transparency but also facilitates informed decision-making in maintenance and operation.
The extra narrow design of these power supply units makes them ideal for resource-optimized control cabinet configurations (IP20 housing). For decentralized structures, IP67 variants are available, offering robust power supply solutions in direct proximity to the consumer.
