The HP 44428A is a 16 channel actuator option for the 3497A data acquisition/control unit. The 44428A consists of 16 mercury wetted from C (single pole/double throw) relays. Each relay can be individually closed and can switch 1 A to 100 V.
The actuator assembly can be used to switch test fixture power or to actuate alarm bells. This flexibility lets the assembly be used as a digital output or as a matrix switch.
