Brief Description

The R&S®TS-PSM4 is the innovative implementation of a rugged, modular switching device for integrating supply current switching into your test system.

The R&S®TS-PSM4 power switching module was developed to add high-current switching up to 16 amps to the standard functionality of the R&S®TSVP test system versatile platform.

Powerful and flexible switching capabilities are combined with ruggedized signal connection and high availability secured by switching cycle monitoring. The R&S®TS-PSM4 can be used in both the R&S®CompactTSVP (R&S®TS-PCA3) and the R&S®PowerTSVP (R&S®TS-PWA3).

A switch cycle counter for reliable operation and monitoring strain of the relays is implemented by an FRAM accessible by the on-board microprocessor. Readings can be retrieved from the module via the IVI switch driver.
