Waterproofing and installation
The housing is sealed, moulded plastic and weighs 167 g. According to the data sheet, IP6K6 applies, and IP6K8 is reached when the protection cap and corrugated tube from the accessories list are used. To comply with the protection class, the wiring harness attached to the mating connector is routed through the corrugated tube, the mating connector is connected to the control unit, and the protection cap is then closed over the mating connector and the corrugated tube. The mechanical instructions must be followed.
Proportional valve drive and I/O details
Eight of the 15 inputs and outputs are I/Os: 4 of them are PWM outputs with integrated current measurement (INA), 2 are PWM capable and 2 are digital outputs, so that four current-controlled proportional valves can be driven. The PWM outputs operate from 3 Hz to 500 Hz. Inputs can be configured as digital, positive encoder signal, analog input (0…11.3 V or 0…23 mA) and current input (500 Ω against GND); a 10 kΩ pull-up against KL30 is also available. The 5 V reference output has a current limit of 500 mA.
Output protection and diagnostics
- Short-circuit protection against GND and UB
- Internal overtemperature protection; latch-off can be realized by the software application
- Wire-fault and short-circuit diagnostics are possible via current sense
- Switching current from 0.02 to 2.5 A (9–32 V DC)

Frequently asked questions
Which connector does it use?
The data sheet specifies the connector as Delphi / Aptiv 211PC249S0033.
What is required for the IP6K8 rating?
IP6K6 and IP6K8 apply when the protection cap and corrugated tube from the accessories list are used: the wiring harness is routed through the corrugated tube, the mating connector is connected and the protection cap is closed.
