It carries SIL 3 per IEC 61508 and Cat. 4 per EN 954, so it fits safety circuits up to the highest integrity level for machine guarding and emergency stop zones. ## End-of-life — sourcing reality This module is end-of-life (EOL) from Siemens. ## Diagnostics and isolation per channel The module provides diagnostic alarm and group error (SF red) indication, with isolation tested at 75 V DC between channels and between channels and the backplane bus. Channels are isolated in groups of 5, which means a fault on one output in a group does not pull down the other group — useful for splitting a safety zone across two groups. ## Switching performance and load limits Resistive load switching is rated at 30 Hz max; inductive load drops to 2 Hz, and lamp load to 10 Hz. The 2 A per channel holds up to 60 °C without derating. The inductive shutdown voltage is clamped to L+ (-53 V) without a series diode, or L+ (-33 V) with one — this limits back-EMF on solenoid or contactor coils.","metaTitle":"Siemens 6ES7326-2BF00-0AB0 SM 326 F-DO 10x24VDC/2A, EOL","metaDescription":"Siemens 6ES7326-2BF00-0AB0 SM 326 fail-safe digital output module, 10 DO, 24V DC, 2A, SIL 3, Cat. 4.
