By September 30, 2021All Products, Products, Schneider
Tesys
  • TeSys “U” is a motor starter used instead of the conventional starting methods (Motor CB + Contactor + Thermal Overload) and it provides full coordination performance and is used up to 15 KW
  • TeSys “T” is a motor protection relay that supports different types of communication (Profibus – Modus – Ethernet …) and is used for motor protection of the LV level from under & over voltage, frequency changes, reversing power direction, and many other LV protection functions.

  • Easy to Install and Use: Only one power base for all control units up to 38 A
  • Efficient: Safe up to 45% of the time for installation and wiring
  • Flexible: Wire the starter completely in the workshop, define the motor on-site with plugin of the control unit
  • Compact: Save up to 57% of cabinet space, reversing starter only 45 mm wide
  • Intelligent: Direct access to detailed information for every motor starter of your installation
  • Safe: Mirror contact as standard
  • Advanced: Advanced motor management

Applications

  • TeSys U all-in-one motor starter is dedicated to direct on line (including reverser) motor control applications.
  • Thanks to the high compactness and outstanding flexibility, it can be well adapted to all types of machines.
  • The strong communication capabilities, high breaking capacity, and total coordination make it highly suitable for process application.

TeSys T Motor management system

TeSys T is a smart motor management system. When associated with a short circuit protection device and a contactor, the device provides full motor monitoring, control, and protection for electrical motors. 

Feautres of Tesys T

The TeSys T motor management system provides protection, metering and monitoring functions for single-phase and 3-phase AC motors up to 1000 A.

TeSys T is a smart system that can be adapted to any customer request with Custom Logic and is natively connected to any PLC on 6 protocols.

The range is comprised of three components:

  • Main Controller: provides current-based protection and monitoring, communication, control, and statistics features.
  • Optional expansion module: adds voltage, power, and energy measurement
  • HMI: a flexible option to quickly monitor and commission a TeSys T system. Control features are also available through the HMI

Benefits of TeSys T

TeSys T is a compact, smart, and easy to select a product that can be fully integrated into any automation system or connected to any PLC of the market. Advanced protection, monitoring, and pre alarming will dramatically increase process availability (less downtime) and reduce operating costs.

Flexibility

  • Fully open, it communicates with Ethernet protocols: Modbus/TCP and EtherNet/IP, Modbus, CANopen, DeviceNet, PROFIBUS DP protocols.
  • Designed to fit in IEC and NEMA MCC, it integrates 10 predefined control schemes and one custom mode that adapts control mode, product behavior, and even protections to any requests.
  • TeSys T can be controlled through its terminal strip, HMI, or communication port. Having a central control in TeSys T will reduce the complexity of your installation, reduce the need for auxiliary equipment, save space and reduce costs.
  • Fully integrated into Blokset, Okken, and Model 6 iPMCC TVDA, Advantys STB solution, and in the Foxboro DCS.

Trust 

  • TeSys T is quickly becoming a worldwide standard thanks to its flexibility. Lots of customers in Metal/Mining/Mineral, Oil & Gas, Water Wastewater, and other types of applications trust TeSys T to deliver.
  • TeSys T is highly reliable and has a very long product life thanks to a state-of-the-art component selection (FRAM memory, Flexrigid PCB, etc.) to the all-in-one design and advanced electronic protection.
  • TeSys T Ethernet version enjoys a daisy chain loop for the higher redundant system.

Prediction and Energy Management 

  • TeSys is able to accurately monitor current, voltage, and power over a wide range and features advanced protection and warning functions. This accuracy is key for effective protection and preventive maintenance.
  • The advanced protection and warning functions will allow TeSys T to predict process shutdowns and manage processes more efficiently.
  • The power monitoring capabilities make TeSys T a green motor management system because it can help to better manage energy consumption.
  • TeSys T is fully integrated into Powerlogic systems to fully utilize its power and energy monitoring capabilities.
