RVL got a reaction from Ivaylo Angelov in EGT Conditioner
Hi Guys,
EGT-K 2CH power consumption is ~2-3mA @ 12V.
OUT ground is internally connected with IN ground.
Sensors ground in your ECU is chassis ground with separate filtering for analog circuit - right?
You can connect it in two ways:
Using vehicle ground (chassis ground):
- EGT-K OUT signal to Adc input in ECU
- EGT-K OUT ground left floating
- EGT-K VCC input to +IGNITION or +BAT
- EGT-K GND input to -BAT or chassis ground.
Using ecu sensor ground:
- EGT-K OUT signal to Adc input in ECU
- EGT-K OUT ground to ECU sensor ground
- EGT-K VCC input to +IGNITION or +BAT
- EGT-K GND input left floating
Both cases will work. Second case will be more immune for external noise on ECU's power line.
Hope it helps.
