Product details

Integrator note – 32-point DO for S7-400 racks

The 6ES7422-7BL00-0AB0: Short-circuit protection is clocked electronically with a typical response threshold of 0.75 to 1.5 A; wire-break detection flags any open load carrying less than 0.15 mA. Diagnostic and hardware interrupts are parameterizable via the configuration software.

For uprating (paralleling outputs), Siemens allows it only within the same group of 8. Redundant control of a load is also limited to outputs of the same group. The module can also drive a digital input directly when configured for that purpose. Power loss is 8 W typical. Supply voltage range is 20.4 to 28.8 V DC. Residual current at signal '0' is maximum 0.5 mA; minimum voltage for signal '1' is L+ minus 0.8 V.

Frequently asked questions

Will 6ES7422-7BL00-0AB0 drop into a panel designed for 6ES7222-1BF22-0XA0?

No. The module uses the S7-400 backplane and is 25 mm wide with a different mounting profile. The S7-200 peer is a different physical standard; rewiring and rack change are required.

What are the key dimensions of this module?

Height 290 mm, depth 210 mm, width 25 mm. Weight approximately 600 g.
