TSA Series

Starts, stops and protects

Emotron TSA softstarters take motor control to a new level. Soft torque starting, intelligent load monitoring and smart stops are all included and accompanied by a robust and compact design. The softstarter is developed for pump, fan, compressor, blower, crusher, conveyor, mill, mixer and saw applications.

Smooth starts reduce your costs

Adjusting the motor torque is best done by controlling the current in all three phases. 3-phase control offers symmetrical and balanced currents without the drawbacks of additional energy loss, noise and vibration normally connected with 2-phase softstarters.

Protect your process and maximize efficiency

A built-in load monitor protects your machine and process against costly downtime, equipment damage and break-down. It reacts immediately if a crusher is jammed, a pump is running dry, a compressor is idling, or a fan is operating inefficiently due to a blocked filter. This is achieved by continuously calculating the motor torque used. Any deviation from your selected load levels will result in a warning or a quick but smooth stop.

Protect your motor

All Emotron TSA softstarters have a motor PTC thermistor input for thermal protection of the motor as standard. The isolated thermistor inputs conform to DIN 44081/44082. In addition, the softstarter allows for connection of up to 6 PT100 temp sensors. The softstarter software also includes an easy to use I2t motor thermal protection function.

Smart stops – smooth or quick

Emotron TSA offers efficient solutions, whether the need is a smooth or a quick stop. A linear stop of a pump eliminates the risk of water hammer, without the need for motor-controlled valves. Built-in braking functionality ensures quick and safe stops of mills and saws without mechanical brakes.

Slow speed and jog operations

Apart from ramping up and down the speed between zero and rated motor speed, Emotron TSA softstarters offer low speed operation in both forward and reverse without additional hardware. Slow speed or jogging forward or backward can be useful for aligning a load or having the motor running at low speeds for test or service purposes. Examples of applications where such low speed or jog operation is valuable are loading/unloading of centrifuges or mixers, or positioning feeding conveyors.

Compact dimensions

Emotron TSA softstarters are among the smallest in their class. They feature a compact yet user-friendly design due to their space-efficient construction and unique by-pass design.

Real-time clock and programming blocks

The Emotron TSA softstarter offers built-in programming blocks, such as logical functions, comparators, SR Flip-Flops, counters and timers. This opens the way for customising functionality according to your requirements. A Real Time Clock provides information about the actual date and time of the day. The real time information is used for time registration in the event log and to enable preprogrammed starting and stopping at certain date and time.

Multi-lingual control panel with single-function keys and copy function

Designed for global application, the Emotron TSA softstarters carry a multi-lingual display unit as standard. The control panel has an easy-to-use menu system and dedicated menu and start/stop keys.

Options add functionality

A number of options let you customise the functionality of the the Emotron TSA and fully utilise the product according to your needs.

External control panel

The external control panel is used to move the control panel from the softstarter to the front of a panel door or a control cabinet. The maximum distance between softstarter and an external control panel is three metres.


Communication options include fieldbus communication via Profibus DP and DeviceNet, Industrial Ethernet communication via Modbus/TCP, EtherCAT and Profinet 1 or 2 ports, and serial communication via USB or using RS485/Modbus RTU protocol (RS232 is standard built-in).

Motor protection

PTC and PT100 sensors can be connected to monitor motor temperature and give process feedback without using a transmitter. It’s possible to connect up to 6 PT100 sensors.

Extended digital I/O (3+3)

Digital I/O extension boards with 3 digital inputs + 3 relay outputs per board. Max 2 boards.
