Product details

The 6ES7522-1BF00-0AB0: Eight-channel 24 V DC output for S7-1500; DQ and MSO both listed as yes — discrete output plus motion-synchronous output support. PWM on two channels at max 500 Hz, but requires firmware V2.1.0 or higher and FS02 hardware revision. Switching on typ. 80 µs, off typ. 300 µs — fast enough for typical logic loops but not for sub-millisecond counter or encoder replacement. Load range 12 Ω to 4 kΩ, short-circuit proof, group error and diagnostic alarm available.

Integration Notes

Width 35 mm, depth 129 mm, height 147 mm — fits standard S7-1500 profile rail, occupies one slot. Power loss typ. 5.6 W, 6.8 W under PWM operation; ensure adequate ventilation in dense builds.

Frequently asked questions

What does DQ and MSO mean on this module?

DQ (Digital Output) and MSO (Motion Synchronous Output) are both supported, enabling standard discrete control and synchronized output for simple motion applications.

Can this module output PWM?

Yes, two channels can operate at max 500 Hz PWM, but only with firmware version V2.1.0 or higher and hardware revision FS02.
