Product details

The 6ES7522-5FH00-0AB0: Supports DQ (device qualification) and MSO (maintenance shut-off) functions, enabling diagnostics and safe shutdown within the fail-safe CPU architecture. No PWM capability—triac outputs are strictly on/off for AC mains.

The module occupies one S7-1500 slot at 35 mm width, 147 mm height, 129 mm depth. Bonds to the backplane via standard U-connector; isolation tested at 3 100 V DC. Unshielded cable runs up to 600 m; shielded up to 1 000 m. Position it away from high-voltage drives to keep common-mode noise off the triac triggers. Channel status shown per green LED; module diagnostics via red LED. FW update possible, firmware revision V 1.2.0. Prioritized startup reduces bus scan time on power-up—useful for sequenced machine starts.

Frequently asked questions

What do DQ and MSO mean on this module?

DQ (device qualification) allows the module to be used in fail‑safe circuits. MSO (maintenance shut‑off) enables a safe shutdown under software control. Both are supported.

What is the maximum cable length?

Unshielded cable up to 600 m, shielded cable up to 1 000 m.

Does the module have a built-in fuse?

Yes, a 6.3 A slow-blow melting fuse is integrated per module, protecting all eight outputs collectively.
