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.
