Pickering 40-670A-622-198/1 PXI Reed Relay Multiplexer Module
The Pickering 40-670A-622-198/1 is a PXI very high-density reed relay multiplexer module designed for serving in automation. It provides 198 single pole channels for automated switching architectures and occupies a single three-unit PXI peripheral slot within modular chassis deployments. It is deployed where compact high channel count signal routing is required under control. Each channel within Pickering 40-670A-622-198/1 uses ruthenium sputtered reed relays for repeatable switching. Its relay contacts present resistance below approximately 1 ohm supporting accurate voltage measurements in circuits. Insulation resistance reduces leakage between signal channels effectively and its differential thermal offset below 10 microvolts reduces measurement error budgets in data acquisition and instrumentation.
The 40-670A-622-198/1 permits switching voltages of 150 V DC or 100 V AC and its maximum switch current is 0.5 A which defines the continuous carry current rating. Each channel of this multiplexer module supports 10 W resistive switching power within specified operating limits. These ratings enable routing of control signals and instrumentation paths while maintaining electrical safety margins. Its operate and release times are below 0.5 ms for enabling deterministic signal path selection and its reed relay life approaches 1 × 10â¹ operations when switching low power loads. At full specified load the relays sustain life exceeding 1 million operations for dependable deployment. It connects through a 200-pin low force helix front panel connector interface. The compact connector format supports harnessing to terminal blocks interface panels or signal conditioning hardware. Low channel to channel capacitance and high isolation supports clean switching of frequency analog signals. The analog bandwidth extends into the MHz range although value depends on load and cabling.
The 40-670A-622-198/1 derives all operating power from the PXI backplane 1.3 A. Its power dissipation therefore ranges from 1.5 W typically up to 7 W maximum. This controlled thermal profile simplifies chassis cooling calculations in multi slot automation and measurement platforms.
Its environmental specifications permit operation between 0 and 55 °C without performance degradation and its altitude capability covers operation to 1 6404.2 ft. Its compliance with PXI specifications ensures fully electrical compatibility with 3-unit PXI or CompactPCI chassis. The unit’s driver support includes IVI VISA and programming environments enabling integration into established automation software infrastructures.
