Controller Interface Board

The controller interface is divided into two identical sections: Section 1 on the right and Section 2 on the left. Each section can connect to one controller board. A single power source, located in Section 1, is used for both sections. The signals from the DB37 are equally distributed between both sections, according to the Pin Assignments table.

Test Point Area

By default, the OP8665 board has a probing area providing test points with an integrated 0 Ohm resistor: the user can probe the signals either before (PRE, HIL side) or after (POST, controller side) the signal break.

Typical circuit diagram

The OP8665 controller interface also has an available option to add a breakout area (with pins and jumpers) to open or short a signal. The user can move the jumper to an open/short position to simulate faults or to jump a signal.
