Keithley SSIO-24 Solid State Relay Module Accessory Board

Keithley SSIO-24 Solid State Relay Module Accessory Board is a 24-channel accessory designed to accompany the Keithley SSIO-24 Solid State Relay Module. It provides a dedicated interface to manage twenty-four relay channels within a Keithley test system, simplifying wiring, organization, and expansion of relay control tasks. This accessory is used in laboratory and instrumentation environments where multiple solid-state relays must be controlled or automated, enabling organized routing of control signals to relay outputs and supporting batch switching in test fixtures. The SSIO-24 designation identifies compatibility with Keithley’s modular relay architecture, helping ensure reliable operation in precision measurement setups that rely on solid-state switching. By adding a 24-channel accessory, users can scale their relay control capacity within an existing SSIO-24 configuration, aligning with typical lab practices for automated testing, sequencing, and load isolation workflows. As part of the Keithley ecosystem, this board is designed to integrate with other SSIO-24 components to maintain consistent performance and signal integrity across multiplexed relay tasks.
