OP8660 System Description

The OP8660 HIL Controller and Data Acquisition Interface is designed to be used with a real-time simulator (such as OP5600 or OP5700) to provide supplementary signal conditioning. 

It is designed to be used either as a desktop (or shelf top) or installed in a standard 19'' rack and uses standard connectors (DB37, DB9, and banana jacks) without the need for input/output adaptors which makes connections for monitoring quick and easy.

The rear of the chassis provides DB37 connectors to connect the OP8660 to the real-time simulator, while the front provides connectors (banana jack or DB9) for connecting client-side applications such as inverters, encoders, monitoring and measuring devices.

The unit includes four OP5511 high current and high voltage input conditioning modules, which convert high current and high voltage signals coming from the external device to ±10V voltage signals compatible with the real-time simulator's inputs.

By installing the HIL Controller as a link between the unit under test (ECU, motor controller, etc.) and the simulator, you can insert a fault at any point in the test to assess how the unit reacts to the fault.


  • DB9 inverter and encoder connectors.
  • Banana jack high current and high voltage measurement connectors.
  • Banana jack analog input (+/-16V) monitoring connectors
  • Banana jack analog output (+/-16V) interface connectors
  • Banana jack digital input (0-30V) monitoring connectors
  • Banana jack digital output (0-5V) interface connectors
  • DB37 connectors for quick connections to the real-time simulator (all DB37 use common pin assignments).
