It sits in the safety segment of the backplane, separated from standard I/O, and the 40-pin front connector carries both load and signal wiring. The 2 A per channel holds up to 60 °C ambient — horizontal installation, no derating needed. Vertical mounting drops the limit to 1 A. ## Lifecycle status — EOL phase, sourcing reality No official successor order code from Siemens exists for this exact EOL variant. For a BOM freeze or long-term support plan, confirm the replacement path with the safety CPU compatibility list. ## Cable length and diagnostic reach Unshielded cable runs up to 50 m; shielded runs up to 30 m. The module reports diagnostic alarms (parameterizable) and a group-error SF LED — useful for fault isolation on a long run to a remote valve island. Short-circuit protection is built in per channel, with inductive shutdown clamped to L+ (-33 V). No reverse-polarity protection on the load supply — wire 2L+ and 3L+ correctly.","metaTitle":"Siemens 6ES7326-2BF40-0AB0 Failsafe DO, 8×2 A, SIL3","metaDescription":"Siemens S7-300 failsafe digital output module, 8 channels at 2 A, SIL 3 / PL e.
