It draws 50 mA at 5 V DC from the backplane and consumes 0.5 W typical, leaving headroom for other signal boards. The 9-pin D-sub connector (pin, not socket) supports Freeport programming, Modbus RTU, and USS protocols. The 9-pole D-sub is a male connector (pin), so your cable assembly needs a female (socket) end. Shielded cable length is rated to 10 m — enough for a drive cabinet or local sensor cluster but not a plant-wide run. IP20 means it lives inside an enclosure; no washdown exposure. The 35 mm width and 16 mm depth let it snap into the standard S7-200 SMART signal-board slot without stealing DIN rail space.","metaTitle":"Siemens 6ES7288-5CM01-0AA0 SIMATIC S7-200 SMART RS-485 Comm","metaDescription":"SIMATIC S7-200 SMART CM 01 RS-485 communication module with 9-pin D-sub, supports Freeport, Modbus RTU, USS.
