Keithley Instruments MSSR-32 Relay Board 32 Channel

Keithley Instruments MSSR-32 Relay Board is a 32-channel relay module (model MSSR-32), cataloged as MSSR32 and linked to part numbers 14071 and PC6432, representing a dedicated relay expansion option intended for inclusion in measurement and test systems that require multiple control paths. The board consolidates 32 independent relay channels into a single interface, enabling the switching of multiple external circuits from one control source and simplifying signal routing and automation workflows, reducing wiring complexity and potential misrouting in multi-branch test setups. Identified by its MSSR-32 designation and the MSSR32 alias, this Keithley accessory serves as a straightforward, purpose-built solution for expanding relayed I/O capacity within compatible instrumentation ecosystems, supporting more complex control schemes without introducing separate controllers or additional interconnects. As a Keithley MSSR-32 relay board, the device is defined by its 32-channel capability and its model identifiers, MSSR-32 and MSSR32, with part numbers 14071 and PC6432.
