10 fail-safe outputs at 2 A, SIL 3 / PL e
The Siemens 6ES7326-2BF10-0AB0 is a fail-safe digital output module for the S7-300 system, delivering 10 outputs each rated 2 A at 24 V DC. It carries SIL 3 per IEC 61508 and PL e per ISO 13849-1, making it suitable for safety circuits up to Cat. 4 per EN 954.
Derating and load limits
The per-channel current is 2 A at 40 °C, derating to 2.4 A max at that temperature. At 60 °C the module delivers 6 A total across all outputs. Resistive and inductive loads switch at up to 25 Hz; lamp loads at 10 Hz. The module draws 100 mA from the backplane bus and up to 100 mA from each load supply leg.
The module snaps onto a DIN rail. Dimensions are 40 mm wide, 125 mm high, 120 mm deep. It requires a 40-pin front connector (sold separately). Unshielded cable runs up to 600 m; shielded up to 1 000 m. Channel-to-channel isolation is tested at 370 V for 1 minute.
