Keithley SRA-01 IO Relay Board Module Assembly

Description:

The Keithley SRA-01 I/O Relay Board Module Assembly is used to interface industry-standard solid-state I/O modules with digital I/O and combined analog/digital data acquisition boards. Commonly installed in industrial automation systems, automated test equipment (ATE), process control systems, and data acquisition applications where AC and DC signals must be monitored or switched through isolated I/O modules. Maintenance technicians, system integrators, and automation engineers use this relay board module assembly for machine control, system expansion, equipment upgrades, and replacement of legacy industrial I/O interface hardware. 

Applications:

The Keithley SRA-01 is designed to provide a convenient interface between compatible Keithley digital I/O boards and industry-standard solid-state input/output modules. It supports both signal sensing and load switching for AC and DC applications and is commonly used in factory automation, laboratory instrumentation, manufacturing equipment, process monitoring, relay control, alarm systems, and industrial control panels requiring electrically isolated digital I/O.
