SAG

Acquisition and Signal Generator for ECU.

The SAG module can be installed on a research or production bench. This equipment is used to simulate a vehicle environment for the ECU. It complements our existing systems for injectors control (IPod Coil) and pressure control rail (HPC), but now it opens to the ECU to test equipment closer to their actual operation.

To run the ECU on the bench, the SAG module provides battery power (12V or 24V) and simulates the vehicle sensors to vary the ECU operating point. In general, the sensors on a vehicle return different kind of signals: a 0- 10 V voltage, a frequency through a TTL signal, a duty cycle (PWM) through a TTL signal, logic information through a potential free contact.

The SAG's role is to simulate this kind of information.
