IRVINE, Calif. – AMETEK VTI Instruments in Irvine, Calif., is introducing the EMX-75XX series of PXI Express digital I/O modules for power electronicstest and measurement applications.

The EMX-75XX series is a family of PXI Express modules that support several 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 simplify external cabling. Using built-in clamping diodes, the EMX-7510 has the ability to sink as much as 300 milliamps to drive and sense external devices such as relays.

Several logic levels are supported including TTL and LV TTL. Internally supplied voltage levels of 3.3, 5, 12, and 24 volts as well as user-defined voltage levels from 2 to 60 volts also are supported.

In addition, 1000-volt 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 I/O states without the use of external software.

As part of VTI’s Core ATE suite of functional test cards, the EMX-75XX series integrates with other modules to address automatic test and functional test applications.

The EMX-7510 is built to deliver selectable voltages at 300 milliamps on each channel, including a voltage range from 2 to 60 volts using built-in clamping diodes. With eight channels at eight bits each, it functions as a source and a sink card.

The EMX-7511 and EMX-7512 are dedicated TTL or LV TTL cards, respectively, with 64 channels available.

The EMX-7513 offers 32 isolated channels in and 32 isolated channels out. It functions from 2.5- to 60-volts and 50 milliamps sink/source. It is useful in applications where optical isolation and integrity are required.

The EMX-7514 and EMX-7515 are dedicated 64-channel output and input cards, respectively. They are for situations with high channel counts that are not bidirectional. The EMX-7514 offers 50 milliamps sink/source either AC or DC at 60 V. It is potential-free and offers optical isolation. The EMX-7515 provides a range of 2.5 to 60 volts and optical isolation for dedicated input applications.
