Type SCS20

~ 73 mm
Typ SCS20 von E-T-A: Das smarte Modul SCS20 ist ein universell einsetzbares Kleinsteuergerät in einem Modulgehäuse.


The smart SCS20 module is a universally usable mini control unit in a modular housing with blade terminals. Via a customer-specific software, this component can easily be included in existing systems.

A particular feature of the SCS20 is its great number of interfaces:

  • six IO ports which can be used as inputs or outputs
  • two additional low-power outputs
  • two H-bridge outputs which can be activated with up to 10 A each; alternatively, 4 loads can be operated with max. 1 A each
  • CAN communication: CAN high speed protocol as a standard; CAN low speed or RS232 are optionally available


  • Versatile smart relay for demanding applications with 12 interfaces and additional CAN communication.
  • Reduction of complexity through a customer-specific software, which allows addition of any kind of sensors and equipment options.
  • High availability over the entire life span due to state-of-the-art semiconductor technology.

The smart SCS20 relay is available for DC 12 V and DC 24 V applications.

Software and specification requirements are set up in direct co-operation with our customers. Alternatively, we will shortly be able to offer a programming option for these mini control units by an intuitive, graphical design environment.

Coming soon.

Scopes of applications

  • Extension of an existing CAN system The SCS20 can handle high speed CAN bus. RS232 or low speed CAN optionally possible.
  • A sensor or other equipment options can be added which are queried or controlled by the central control unit.
  • Control of two motors with up to 20 A via two H-bridge outputs. Both motor bridges provide overload detection. Alternatively, 4 loads can be operated with max. 10 A each.
  • Internal measurement of temperature and voltage. The software can then take this information into account.
