Electronic Solid-State Relay

Electronic Solid-State Relay

Bidirectionally suitable for automotive

Relays used so far are interchangeable 1: 1

control is polarized 1: 1

Can also be used for high currents up to 40A

Can switch loads in plus or to ground

Lower temperature development like conventional relays

Application where only small drive currents are available or where many switching cycles are available

Universally applicable like a mechanical contact
o e.g. Triggering the central locking, controlling windows, switching on lamps etc.

2-channel PWM-filter



2-channel PWM filter:
In almost all vehicle industries, the trend has arrived to replace incandescent bulbs by LED technology or retrofit to LED technology. In order to benefit from the resulting energy savings, the Carsig GmbH developed the PWM-filter. It ensures a failure-free conversion even for vehicles with micro hybrid systems.

Due to the higher vehicle voltage the lamps are driven through the PWM signals, so that the nominal voltage won't be exceeded. The Carsig PWM filter fills the break times by supplying battery voltage to the PWM filter.

Therefore the headlights are receiving a constant energy supply. 


headlights in micro hybrid systems



  • no flickering of the LED headlights
  • unlimited lifecycle and low risk of short circuit, through the waiver of capacitors
  • failure-free retrofitting even for vehicles with micro hybrid systems

The wiper interval switch controls the length of the wiper breaks from a windshield wiper in the intermittent operation. At the rotary button there are two to twenty wipers per minute adjustable.


special and commercial vehicles



  • Overcurrent shutdown to prevent damage of the wiper motor or the mechanical system.
  • Protected against surges, electrostatic discharge and transient disturbances.
