1336S-BRF50-AA-EN-HA2-L4  A-B  Filter Modules

I/O and Safety Features: In terms of I/O, the PowerFlex 525 is equipped to handle typical control and feedback needs. It provides 7 digital inputs (6 programmable and 1 dedicated safe-stop), 2 analog inputs (one bipolar, one unipolar, independently isolated), 1 analog output (0–10 V or 4–20 mA selectable), two assignable solid-state optocoupler outputs, and two relay outputs (Form A and Form B) for signaling run/ fault conditions or controlling external devices (PowerFlex 525 User Manual). The drive’s control inputs can be configured for either sink or source mode (24 V DC) via a jumper, accommodating different wiring preferences. Critically, the PowerFlex 525 includes an integrated Safe Torque Off (STO) feature as a standard safety function. The STO circuitry, when activated (by a safety relay or controller in a safety circuit), immediately removes gate firing signals to the output IGBTs, preventing the drive from energizing the motor while not physically removing power to the drive. This allows a category 3 / PL d safety stop without full power-down, enabling faster restart after a safety event. The STO function in the 525 is TÜV certified to meet ISO 13849-1 PL d and IEC 61508 SIL 2 safety standards, which means it can be used in applications requiring functional safety compliance up to those levels (Rockwell product page – Certifications). In practice, using the built-in STO can eliminate the need for external contactors for many installations, simplifying the panel design and improving uptime (since a safety stop can be cleared without waiting for a power cycle of the VFD). Aside from functional safety, the PowerFlex 525 carries a broad set of certifications and standards compliance: it is CE marked for the Low Voltage Directive and EMC Directive  in Europe (EN 61800-5-1, EN 61800-3 emissions/immunity), UL Listed and cUL certified for use in the US and Canada, has ATEX certification for use in explosive atmospheres (rated for Group II, Category 3 applications when used with an ATEX-certified motor), and even is compliant with SEMI F47 voltage sag immunity for semiconductor industry use, among others. Rockwell documentation also notes compliance with the IEC 61800-9-2 Ecodesign standard (meeting IE2 drive efficiency classification), and options for meeting marine certifications like Lloyd’s Register for shipboard applications. In short, the 525 is designed to meet modern efficiency and safety standards globally – all leading to easier regulatory acceptance in various industries and regions.
