It provides 2 safety-related digital inputs rated for mechanical switching contacts and 2 standard solid-state outputs, each powered from the 24 V DC AUX supply. The module communicates over the AS-Interface bus, drawing up to 60 mA from the bus for its own electronics. The 22.5 mm housing (S22.5F) is the SlimLine footprint — it snaps onto a standard 35 mm DIN rail and saves panel width compared to the wider 45 mm safety relay blocks. The AS-Interface operating voltage range of 26.5 to 31.5 V DC matches the standard AS-i power supply output; the module also requires a separate 24 V DC AUX supply to power the two solid-state outputs. The built-in watchdog, short-circuit protection, and induction protection mean the module handles its own fault monitoring and output protection without external fusing or suppression diodes. The screw terminals accept the AS-i bus cable and the 24 V DC AUX supply wiring. The front addressing socket lets you set the AS-i slave address without removing the module. The yellow LEDs indicate I/O state per channel; the green/red LED shows AS-Interface communication and diagnostics. The ID/ID2 code B/F is factory-set and identifies the module profile to the AS-i master. ## Environmental limits","metaTitle":"Siemens 3RK1405-1BE00-0AA2 ASIsafe SlimLine, 2 F-DI/2 DQ, IP","metaDescription":"Siemens 3RK1405-1BE00-0AA2 ASIsafe SlimLine module, 2 safe inputs, 2 standard solid-state outputs, 22.5mm wide, IP20.
