It handles a single 24 V DC output, with the L+ supply dropping up to 0.8 V under load — something to account for in voltage-sensitive loads like valve coils or indicator lamps. The module packs 16 bytes of input data space and 12 bytes of output data space. In Fast mode — enabled from firmware V1.2 or higher — the input data shrinks to 4 bytes and output data to 0 bytes, freeing bandwidth for high-speed signal processing. Motion Control uses 4 bytes of the output region, so if you are running both Fast mode and Motion Control, watch the data allocation. ## Panel fit and wiring constraints The module is 15 mm wide, 73 mm tall, and 58 mm deep — it clips onto the DIN rail with a BU type A0 BaseUnit underneath. That 15 mm width is tight for a crowded enclosure; you can fit several per row without eating up rail space. Input voltage is rated at 24 V DC, with signal '1' threshold from +11 to +30 V and signal '0' from -5 to +5 V. The module draws about 1 W typical power loss. Wiring runs up to 1 000 m shielded or 600 m unshielded.","metaTitle":"Siemens 6ES7138-6AA00-0BA0 Digital Output Module, 1 Channel","metaDescription":"Siemens ET 200SP digital output module, 1 channel, 24 V DC, 58 mm depth, 15 mm width.
