Each multiplexer channel is equipped with an additional monitoring switch that allows the user, via an external measuring device, to verify that the multiplexer channels are "open" before applying test signals. This feature is essential in applications where the incorrect or unintentional application of signals could damage the device under test.
By introducing the new monitored multiplexer concept to Pickering's existing range, the 40-619 is available in nine switching configurations from 16:1 to 128:1, providing flexibility in test system design. It utilizes high-quality electromechanical signal relays (EMRs) suitable for switching loads up to 2A at 250VAC/DC. The compact, single-slot footprint allows for the implementation of a monitoring function while minimizing chassis slot space.
Pickering's Switching Product Manager, Steve Edwards, comments: "The 40-619 provides a high-density, low-cost integrated monitoring solution, eliminating the need for complicated external wiring and additional test code, which are required when implementing a similar topology using discrete switching. The module is designed for signal routing in automated test equipment (ATE) and data acquisition systems, targeting applications where channel status confirmation is required before applying the test signal."
The modules are compatible with Pickering's eBIRST™ diagnostic testing tool. Like all Pickering products, the 40-619 monitored multiplexer modules come with a three-year warranty and include spare relays, enabling customers—with proper training—to perform on-site repairs and minimize system downtime. Pickering also offers a range of standard and custom interconnect accessories to support the 40-619 family.
