Product details

Field integration note

The 6ES7522-1BL01-0AB0: 32-channel digital output module for the S7-1500 backplane. Rated for 24 VDC outputs at 0.5 A per channel, with module supply output (MSO) meaning the module can supply power to downstream sensors or loads via the backplane. Switching times: 0 to 1 in 100 µs, 1 to 0 in 500 µs — fast enough for most discrete control loops but not intended for PWM (PWM not supported). Diagnostics suite includes wire-break and short-circuit detection per channel, plus group error and maintenance interrupt. Status and error LEDs per channel for on-site troubleshooting.

Sufficient clearance for cabling at the front connector. Requires firmware version V1.1.0 or later. HW functional status from FS02. Supports isochronous mode for synchronized applications.
