It is rated for continuous operation with a typical power loss of 1 W, keeping thermal contribution low in dense panel configurations. Physical dimensions — 52 mm depth, 81 mm height, and the slim 15 mm width — allow it to slot into the ET 200S rail alongside other modules without consuming extra space. Sourcing is straightforward — specify the part against your BOM line and we will quote to order; no last-time-buy or surplus channel required. ## Integration Notes Mounts directly on the ET 200S rail using the standard screwdriver-actuated latch. The 15 mm width matches the baseUnit pitch; no filler modules needed. The 52 mm depth fits within the standard ET 200S enclosure depth profile — verify gland plate clearance only if using extended terminal blocks on adjacent modules. Four SI IO-Link master channels handle point-to-point communication with IO-Link v1.1 devices; each port can also operate as a standard digital input if the device is configured as SIO mode.","metaTitle":"Siemens 6ES7138-4GA50-0AB0 ET 200S IO-Link Master, 15mm","metaDescription":"Active Siemens ET 200S electronics module; 4 SI IO-Link master, 15 mm wide, 1 W power loss.
