Overview of the EA interface cards
The EA interface cards are pluggable digital resp. analogue cards for new and upcoming series of or power supplies
or other devices, like electronic loads. Depending on the device, one or two cards slots are available which determines
if all features of these cards are usable or not. Some features require two cards to be equipped. The gateway
feature enables linking (gateway) of different bus systems (networks). All digital cards serve for the transmission
of the communication between controlling unit (PC) and controlled unit (power supply). The amount of controlling,
measuring and monitoring features is depending on the device which the cards are equipped in.
Key features:
• Retrottable, simple installation (plug’n’play)
• Easy conguration via a setup menu on the device
• Up to 2 different pluggable interface cards possible per device
• Gateway functionality at 2 cards (see example below)
• Simple networking of different device to each other and to a PC (at USB multiple device via hubs and
at CAN normal networking from device to device)
• Support of master-slave resp. Share-bus operation with totals formation of voltage, current and power
as well as centralised alarm managment ( only in System Link Mode)
• Galvanic isolation up to 2000V
• Software CD, user manual and cables included (CAN, USB, RS232)
