The safety outputs switch at 24 VDC and are rated 2 A per channel, with overload and short-circuit protection built in. The inputs detect signal \"1\" from +15 to +30 VDC with a typical current draw of 4.85 mA at 24 V, making them compatible with standard 3-wire PNP safety sensors and e-stops. ## Fit and integration constraints Ambient range is -30 °C to +55 °C with no derating on the outputs up to the full 4 A total (2 x 2 A) at 55 °C. The 4.7 W typical power loss stays within the thermal budget of a sealed IP67 enclosure, but if the module is inside a non-ventilated junction box on a hot factory floor, that 4.7 W plus heat from adjacent blocks should be summed against the box's dissipation rating. For volume or scheduled releases, the RFQ should specify the annual quantity and preferred delivery cadence. ## Diagnostics and commissioning detail The module supports I&M data (I&M0 to I&M3) and a parameterizable diagnostic alarm, so the PROFIsafe controller reads the module identity and fault history without a field visit. Input and output filter times are adjustable from 0.8 ms to 12.8 ms for both rising and falling edges — set to 0.8 ms for fast safety sensors or 12.8 ms to debounce a mechanical e-stop contact. Wire-break detection is active on the outputs when they are off (switched to 0), and the module detects short-circuits on inputs, outputs, and the encoder supply. The 8-byte input and 6-byte output process image maps directly into the safety program's F-runtime group.","metaTitle":"Siemens 6ES7146-5FF00-0BA0 ET 200AL F-DI 4+F-DQ 2, SIL 3","metaDescription":"Siemens 6ES7146-5FF00-0BA0 fail-safe I/O module for ET 200AL. 4 fail-safe inputs, 2 fail-safe outputs at 24 VDC/2 A, SIL 3 / PL e.
