The TeSys Tera advanced control and protection system is designed to provide high performance, efficiency, and connectivity, fulfilling the most demanding needs. Tera Motor Management System - LTMT Expansion Modules. Expansion Modules enable the addition of extra functions to the Main Controller. TeSys Tera expansion has 4 Additional isolated inputs, 2 outputs ‘NO’ contact in DC. 24VDC is used to power the module. It manages the measurement of 3 phase current via integral current transformers from 0.4 to 100 A or up to 810 A by external current transformers. It also measures ground current with internal or external ground sensors, motor temperature, and the inputs and outputs for various motor control modes, detected fault management, and other functions. TeSys Tera is a motor management system that provides full motor monitoring, control, and protection when used with short circuit protection and a contactor. TeSys Tera is a flexible system that integrates seamlessly into your automation system through five major communication protocols. TeSys Tera predicts what will happen in the process, as it accurately monitors current, voltage, and power over a wide range. TeSys Tera has a number of components that increase the flexibility of the system. This expansion module adds functionalities to the TeSys Tera controller. It adds voltage mesurement between phases up to 690 V nominal and 4 additional inputs. Module has 4 Additional isolated inputs, 2 outputs ‘NO’ contact Module has the following certifications: IEC, UL, cUL.
