H1-4

Protected, configurable signal conditioning module

The H1-4 I/O is a HIL module with digital in/out, analogue in/out & resistive functionality. It is a fully configurable signal conditioning I/O module designed for hardware-in-the-loop applications.

Type 4 modules are particularly appropriate for systems where the I/O specification is likely to change (such as one digital input line to another type of input) or where the system may be reconfigured to cover a range of test scenarios which involve significant low level I/O changes.

Modules can be re-configured via the configuration bus, which requires a USB controller. Configurations supporting most common applications are selectable via the data stream.

These modules operate from split supplies with a maximum differential of 36V and an additional logic supply. Unbalanced supplies are common for automotive applications, allowing for high external I/O without compromising maximum working voltages.

The ECU 0V and the HIL 0V are designed to allow for ground offsets without introducing errors
