ET 200SP motor starter

ET 200SP is a scalable, highly flexible and modular I/O system with IP20 degree of protection. As I/O modules, the ET 200SP motor starters are an integral part of this I/O system. They are switching and protection devices for single- and three-phase loads and are available as direct or reversing starters

Motor starter, BaseUnit and 3DI/LC control module

3RK1308 motor starter in the ET 200SP I/O system

Basic functionality

All versions of the ET 200SP motor starters have the following functionality:

Fully pre-wired motor starters for switching and protecting any AC loads up to 4 kW at 400 V AC and 500 V AC
With self-assembling 32 A power bus, i.e. the load voltage is only fed in once for a group of motor starters
All control supply voltages connected only once, i.e. when modules are added they are automatically connected to the next module
Hot swapping is permissible
Digital inputs can be used optionally via a 3DI/LC module
Control of the motor starter from the control system and extensive diagnostics status via the cyclic process image
Diagnostics capability for active monitoring of the switching and protection functions
The signal states in the process image of the motor starter provide information about protective devices (short circuit or overload), the switching states of the motor starter, and system faults.

BaseUnits for motor starters

BaseUnits are components for accommodating the ET 200SP I/O modules. The self-assembling voltage buses integrated into the BaseUnits reduce wiring outlay to the single infeed (both of auxiliary and load voltage).

All modules following on the right are automatically supplied upon plugging the BaseUnits together, if BaseUnits are inserted with routing. The rugged design and keyed connection technology enables use in harsh industrial conditions.

The BaseUnits are available with various infeeds for the motor starters.

3DI/LC control module

This is a digital input module with three inputs for local motor starter functions such as "manual local control", implementation of fast inputs or "end position disconnection".

For a list of all the functions permitted by the 3DI/LC module, see Manual "ET 200SP Motor Starters", "Function overview" section https://support.industry.siemens.com/cs/ww/en/view/109479973 .

The module is plugged into the front of the motor starter from which it is supplied with a DC 24 V operating voltage.

Область применения

The ET 200SP motor starters are suitable for the following applications:

Switching and monitoring of
- 3-phase motors with overload and short-circuit protection (e.g. 400 V asynchronous motors for secondary drives in conveyor systems)
- 1-phase motors with overload and short-circuit protection (e.g. 250 V motors for pump applications)
- Resistive loads by means of current value and diagnosis via the maintenance function (e.g. for gas discharge lamps and heaters)
Plant monitoring and energy management in conveyor systems:
By means of phase asymmetry and zero current detection, for example, it is possible to monitor drive belts and blocking.
Track switching and lifting table control in conveyor systems
Track switches can be implemented by means of the quick stop function and lifting table controls by means of the "immediate end position disconnection" function without any laborious programming.
Safe isolation of drive from main power supply:
The isolating functions in accordance with IEC 60947-1 offer protection against inadvertent activation during plant maintenance.

Особенности

Product advantages

The ET 200SP motor starters offer a number of benefits:

Fully integrated in the ET 200SP system (including TIA Selection Tool and TIA Portal)
Simple, integrated current value transmission
Extensive parameterization by means of TIA Portal
Increase of plant availability through fast replacement of units (easy mounting and plug-in technology)
Longer service life and reduced heat losses thanks to hybrid technology
Less space required in the control cabinet (20 to 80%) as a result of greater functional density (direct-on-line and reversing starters in same width)
Extensive diagnostics and information for preventive maintenance
Parameterizable inputs via 3DI/LC control module
Less wiring and testing required as a result of integrating several functions into a single device
Lower overheads for stockkeeping and configuration as a result of the wide setting range of the electronic overload release (up to 1:3)
Lower technology-reduced inherent power loss as speed-controlled drive systems, also enabling lower cooling requirements (and enabling a more compact design)

The ET 200SP motor starters can be used with highly energy-efficient IE3/IE4 motors.
