The Pickering 40-670A-022-198/1 is a very high density multiplexer module built on the PXI platform for signal routing in automated test equipment and data acquisition systems. This single-slot 3U PXI card delivers 198 channels in 1-pole configuration using high-reliability ruthenium sputtered reed relays. The module supports switching speeds under 500µs with maximum standoff voltage of 100V and maximum switch current of 0.5A. It operates with typical power consumption of 1.4W from the 5V backplane supply and integrates spare reed relays on the circuit board for field maintenance.
