Siemens 6ES7 326-2BF10-0AB0 Digital Output Module

Siemens 6ES7 326-2BF10-0AB0 is a fail-safe digital output module (SM 326) for SIMATIC S7F safety systems, delivering 10 DC 24 V output channels at 2 A each. It provides safety‑related outputs with built‑in diagnostic alarms and LVV up to Category 4 (EN 954‑1) and SIL3 (IEC 61508), with PLE per ISO 13849. The module communicates on PROFIBUS DP or PROFINET networks and supports PROFIsafe V2 for integrated safety networking. It mounts in the SIMATIC S7 rack as part of the SM 326 family and features a 40‑pin connection base for reliable wiring. In practical terms, it is used to switch 24 VDC loads—such as safety interlocks, guarding devices, or emergency‑stop circuits—where fail‑safe outputs are required. This version, 6ES7 326-2BF10-0AB0, is the digital output (DO) extension with 10 channels at 24 V DC/2 A, suitable for safety‑critical automation environments using S7F controllers. It reports diagnostic information to the CPU, aiding fault isolation and maintenance in safety‑critical applications.
