Each output is rated 0.5 A at 24 V DC, with electronic short-circuit protection per channel and reverse polarity protection against destruction. The module supports SIL 2 per IEC 62061, making it suitable for safety-related applications up to that level when integrated into a safety-rated ET 200PRO station. It also provides a diagnostic alarm and group error (SF red LED) for fault indication. ## Switching speeds and load handling Resistive load switching is rated at 100 Hz maximum, while inductive loads drop to 0.5 Hz and lamp loads to 1 Hz. Signal transition times (0→1 and 1→0) range from 1.2 ms min to 4.8 ms max, which sets the update rate for the downstream logic. The module draws up to 20 mA from the 1L+ supply with a typical power loss of 3 W. ## Physical fit and isolation Channel-to-channel isolation is not provided (no isolation between channels), but the module is isolation-tested at 707 V DC (type test). Unshielded cable runs up to 30 m are permitted.","metaTitle":"Siemens 6ES7143-4BF00-0AA0 Digital Output Module, 8 DO","metaDescription":"Siemens ET 200PRO digital output module 6ES7143-4BF00-0AA0 with 8 outputs (4 configurable as inputs), 0.5 A/ch, SIL 2.
