Ametek VTI Instruments has announced that the introduction of its EMX-75XX Series of PXI Express (PXIe) Digital Input/Output (I/O) Modules, the latest addition to its Core Automated Test Equipment (Core ATETM) PXIe functional test solutions.

The EMX-75XX Series is a family of high-performance PXIe modules that support multiple I/O configurations and logic levels. Dedicated input or output modules are available for fixed high-channel-count applications. Other units provide ultimate flexibility with eight 8-bit ports (64 channels) that can be configured as either input or output under programmatic control.

Modules are available with internal pull-up resistors that greatly simplify external cabling. Utilising built-in clamping diodes, the EMX-7510 has the ability to sink up to 300 mA, making it ideal for driving and sensing external devices such as relays.

Multiple logic levels are supported including TTL and LV TTL. Internally supplied voltage levels of 3.3 V, 5 V, 12 V and 24 V as well as user-defined voltage levels from 2 V to 60 V are also supported. In addition, 1000 V optical isolation is available for protection against damaging transient voltage levels. The real-time embedded virtual soft front panel simplifies setup and software debug operations by providing visual indication of input/output states without the use of external software.

As part of the company’s Core ATE suite of functional test cards, the EMX-75XX Series easily integrates with other modules to address a wide variety of automatic test and functional test applications.
