Pickering Interfaces Inc. has expanded its range of PXI fault insertion solutions with the release of the 40-197 and 40-198 modules. Fault insertion modules are used within an automatic test system to simulate common fault conditions such as an open, short to ground or a short to other connections in a device.

The 40-197 module provides up to 34 fault insertion channels that can connect to any of four fault bus connections, each having two different conditions. Each fault insertion channel can switch up to 220VDC at 60W. Each channel can carry and hot switch 2A continuously and up to 6A carry for short duration surge currents. The module bridges the gap between Pickering's simpler fault insertion offerings and more complex FIBO options, the company stated.

The 40-198 module supports up to 20 fault insertion channels that can connect to one of two fault insertion buses, each with three optional fault definitions. With hot switching capabilities of up to 110VDC at 150W, each channel can carry and hot switch 5A continuously and up to 10A. The channel can also carry short duration surge currents. The 40-198 is designed to fill the gap between Pickering's 2A and 10A standard topology fault insertion solutions.

According to the company, the two models use a switch design based around high quality electro-mechanical relays and can be supported in both PXI compliant chassis and Pickering's modular LXI chassis.

All of Pickering's fault insertion solutions are compatible with most common real time operating systems and allow users to choose the size and rating of the fault insertion channels from 2A to in excess of 30A.
