Each output is short-circuit protected and individually diagnosable via the group error SF LED and diagnostic alarm, which simplifies fault isolation on the line. Rated SIL 2, PL d, and Category 3 for safety applications. ## Fit and Derating Rated 2 A per channel; maximum output current 4 A. The module draws 20 mA from the load supply (2L+) and 20 mA from the backplane bus, leaving headroom for additional I/O on the same segment. Mechanical dimensions (45 mm wide, 130 mm high, 35 mm deep) align with the ET 200SP form factor; the 45 mm width occupies two base unit slots on the carrier rail. ## Integration Notes The module accepts unshielded cable runs up to 30 m to the load, so it suits distributed valve islands or motor starters without special cable. For inductive loads (solenoids, contactors), the maximum switching frequency drops to 0.5 Hz; for resistive loads it reaches 100 Hz. Plan the load profile accordingly. Reverse polarity protection on the load supply prevents destruction if the 24 V lines are crossed, though the module will not operate until corrected.","metaTitle":"Siemens 6ES7142-4BD00-0AA0 Digital Output Module, 4DO, 24VDC","metaDescription":"Active production 4-channel digital output module with diagnostics, short-circuit protection.
