72-Channel Digital Output/Relay Driver

The Agilent E***9A **-channel digital output/relay driver is a B-size, *-slot, register-based VXI module. Channels can be used (with external pull-up resistors) as digital outputs or as drivers for external relays.

All channels are referenced to chassis ground, can sink up to **0 mA each, and can switch voltages up to *2 V. Limited power is available on the module faceplate for powering external devices. An on-board jumper permits either the + 5, + *2, or + *4 V VXI power supplies to be used for powering external devices.

Please note that **4 volt power is not available on Agilent B-size VXI mainframes. If **4 volt load power is required in such a case, an external power supply may be used. **4 volt power is available on Agilent C-size mainframes.

The downloadable SCPI and VXI plug&play drivers provide open/close commands for individual **-channel operation or for **-channel dual output operation (the latter is designed specifically for driving latching microwave relays).
