Product details

Eight relay outputs, each switching 24 V DC to 120 V DC or 24 V AC to 230 V AC. The 6ES7522-5HF00-0AB0 sits on the S7-1500 backplane, draws 5 W typical, and supports diagnostic alarm and channel status LEDs. No PWM or isochronous mode – it's a straightforward switched-output relay bank for isolation.

Multi-step output (MSO) supported – logic links and current-sinking or sourcing configurations available. Diagnostic alarm and a MAINT LED (yellow) for predictive maintenance. Prioritized startup and I&M data (I&M0–I&M3) for asset traceability.

Active part, quoted to order. Submit an RFQ with your required quantity and delivery window to confirm lead time.

Frequently asked questions

What does the MSO (Multi-step output) feature allow?

MSO enables switching of different phases across channels without restriction, and supports logic links between outputs for sequence control.

What voltage range does each relay output switch?

Each output can switch 24 V DC to 120 V DC or 24 V AC to 230 V AC, covering most industrial signal and small motor loads.
