CT2N4 is a microcontroller-based wiper control system for 4 wiper motors.
CT2N4 is composed of one (or more) control panel CP4P4 and one relay box SRM4P.
Control panel is connected to relay box by one serial cable (CANBUS cable) with two 8 pole plugs. Every unit has two plugs (in parallel) and any one or both can be used.
Each wiper can be switched on one by one.


  • three intermittent speeds (four in case of single speed motor)
  • one or two continuous speeds
  • synchronized brushes at any mode
  • motor brake
  • washing program
  • an additive control panel CP4P4 can be added to work from different stations

Power supply10V to 30V DC
Internal fuses12A self-resetting fuse for each motor
Stand-by currentLess than 70 mA at 10V and less than 40 mA at 30V
ProtectionsPolarity inversion
Motors- output currentsSingle or double speed – each motor 12 Amps max.
Inputs4 parking switches (open in park position)
Outputs4 SLOW speed Imax = 12A
4 HIGH speed (if using two speed motors) Imax = 12A
1 wash pump (positive pole) SLOW Imax = 1A
Functions3 or 4 intermittent settings
1 or 2 continuous speeds (slow and high speed)
