Siemens 6ES7 326-2BF41-0AB0 Digital Output Module

Siemens 6ES7 326-2BF41-0AB0 is an eight‑channel digital output module (SM 326) for the SIMATIC S7-300 family, delivering eight DC 24 V outputs rated at up to 2 A per channel for safe actuation of loads. As a fail‑safe digital output module (F‑DO), it employs P‑M switching with diagnostic interrupt to support safety‑related applications. The module connects to the backplane via a 40‑pole interface and is designed for use in safety‑critical automation architectures, with qualifications aligning to Cat 4 EN 954‑1, SIL3 IEC 61508, and PLE ISO 13849. Typical applications include driving safety relays, contactors, and actuators in processes where monitored fault states and high‑integrity operation are required.
