The Schneider Electric LTMR27MBD is a versatile motor controller within the TeSys product line. Operating efficiently over a current range of 1.35 to 27 A, this device is designed to manage motor control applications with precision. It utilizes a Modbus RTU communication interface via a two-wire RS-485 connection, allowing seamless integration into automated systems.
For control functions, the LTMR27MBD includes six digital logic inputs operating at 24 V DC, offering flexibility in command inputs. It features three relay outputs that facilitate actuation in various motor control scenarios. The input supply voltage is specified at 24 V DC, with a tolerance range of 20.4 to 26.24 V DC, providing reliable operation under varying conditions. The controller draws between 56 and 127 mA during its operation.
This model is well-constructed to withstand high insulation stress, rated at 690 V, and it features an impulse withstand rating of 6 kV for measured values and 0.8 kV for communication and I/O ports. Furthermore, its short-circuit withstand rating is at 100 kA, indicating a robust design suited for industrial environments. To optimize performance, the recommended fusing includes a 4 A gG rating for outputs and 0.5 A gG for control applications.
Operational capabilities of the LTMR27MBD are maintained across a temperature range of -20 to +60 °C, ensuring reliability in diverse environmental conditions. Installation is simplified with DIN-rail mounting, specifically designed for top-hat TS 35 profiles, enhancing integration into existing control cabinets.
