The Keysight 44728A is an 8-channel relay actuator module designed for automated test and data acquisition systems. It provides remote switching control through eight SPDT Form-C relays capable of handling voltage, current, and power switching tasks. The module connects via screw terminal blocks and integrates directly with Keysight data acquisition platforms to enable complex signal routing and device control in laboratory and production environments.
