Parameters Parameter Specification Product Line TeSys island - Digital Motor Control System Module Type Decentralized Module (DM) - Digital Input / DOL Starter Commercial Reference STBDDI3725KC Motor Starter Type Direct-On-Line (DOL) with integrated electronic overload protection. Rated Operational Current (Ie) 25 A (at 40°C, for AC-3 duty, typically 400V). Rated Operational Power Approx. 11 kW (15 HP) at 400V AC, 3-phase. Rated Supply Voltage 24...690 V AC, 50/60 Hz (for both power and control). Control Supply Integrated from main power (24...690V AC). Communication Interface Integrated into the TeSys island communication bus (via the base unit). Compatible with Ethernet/IP, Modbus TCP, PROFINET, etc. (depends on the Communication Module used). Protection Functions Electronic Overload Protection with adjustable current setting (Ir), trip class selection. Phase loss, asymmetry, and locked rotor protection. Short-circuit protection (requires upstream fuse or circuit breaker). Status Indication LED indicators for: Power, Communication, Run/Stop, Fault/Trip. Control Inputs/Outputs Integrated logic: Configurable via software for local/remote control, interlocks. Includes a local 2-wire control input (Start/Stop) via terminals. Connection Screw terminals for main power (L1, L2, L3, T1, T2, T3) and control inputs. Mounting Plugs directly onto a TeSys island base unit (occupying 1 DM slot). Operating Temperature -25°C to +60°C (with derating above 40°C). Protection Class IP20 (module itself). The assembled island in an enclosure achieves higher IP rating. Standards & Certifications CE, UL, cUL, RoHS, REACH compliant. Conforms to IEC/EN 60947-4-1, -5-1.
