Control Unit for Distributed Drives
The Siemens 6SL3544-0NB02-1BA0 is a SINAMICS G110M Control Unit CU240M with M screw connection, designed for decentralized motor control in conveyor, material handling, and pump applications. It integrates 4 digital inputs, 2 digital outputs, 2 analog inputs, and 1 fail-safe digital input (F-DI) for safety functions, plus a PTC/KTY temperature sensor input and electromagnetic brake control. The IP66 enclosure means it withstands washdown environments and direct hose spray — suitable for food-and-bev lines or outdoor installation without an extra cabinet.
Rated for ambient temperatures from -10 to +55 °C, so it runs in unconditioned plant spaces without derating up to that ceiling. Dimensions 105 x 171 x 205 mm (HxWxD) without the Power Module — plan the gland plate and DIN-rail layout accordingly. The M screw connection terminals accept standard ferruled stranded or solid conductors; strip length per Siemens wiring guidelines.
