Keysight E1339A 72 通道数字输出/继电器驱动器是 B 型、1 槽、使用寄存器的 VXI 模块。通道可用作（使用外部上拉电阻器）数字输出或外部继电器驱动器。
所有通道均以机箱接地为参考，每通道可接收 200 mA，并且能够对高达 32 V 的电压进行开关转换。模块面板可提供有限的功率，为外部设备提供电源。板上跳线支持使用 + 5, + 12, or + 24 V VXI 电源为外部设备供电。
请注意，Keysight B 型 VXI 主机不提供 +24 V 电源。在这种情况下，如需 +24 V 负载功率，则可使用外部电源。Keysight C 型主机可提供 +24 V 电源。
可下载的 SCPI 和 VXI 即插即用驱动程序能够为独立的 72通道操作或 36 通道双路输出操作（后者专用于驱动闭锁微波继电器）提供断开/闭合命令。
