It integrates 4 digital inputs, 2 digital outputs, 2 analog inputs, 1 fail-safe digital input for PTC/KTY motor temperature sensing, and an electromagnetic brake control — all in a 105x171x216 mm package rated for -10 to +55 °C ambient. The IP65 rating means the enclosure withstands hose-directed water and dust ingress, so it mounts directly on the motor or near the machine without a separate cabinet. This part carries a lifecycle stage of mature, indicating it is an established, stable product that remains in the Siemens catalog without imminent phase-out. The latest revision documentation carries a date of 23.06.2021, with standard copyright and change-reservation notice. ## Integration Notes The CU240M DP is a plug-in control unit designed to pair with a SINAMICS G110M Power Module — it is not a standalone drive. The PROFIBUS DP interface connects to the higher-level controller via the standard D-sub connector. The 4 DI and 2 DO handle basic machine sequencing; the 2 AI accept 0-10 V or 4-20 mA signals from sensors. The dedicated fail-safe digital input for PTC/KTY provides direct motor thermal protection without an external relay. The electromagnetic brake control output simplifies hoist or vertical-axis applications. All connections are plug-in type, reducing wiring time during panel assembly.","metaTitle":"Siemens 6SL3544-0QB02-1PA0 SINAMICS G110M CU240M DP, IP65, -","metaDescription":"Siemens SINAMICS G110M CU240M DP control unit, PROFIBUS DP, IP65, 4 DI/2 DO/2 AI, mature lifecycle.
