The pluggable interface cards, made by EA, offer a unified usability for current and future series of devices. They can be used as the situation requires it. Just plug them (with some restrictions when using two cards at once) and the devices offer either a: |
The digital variants for CAN, USB, RS232, GPIB, Ethernet or Profibus offer a plenty of possibilities to the user when it is required to control, measure and monitor multiple device of various kinds. They even allow to network our devices to a system. A unique feature is the gateway functionality (PSI 9000 series only). This links the CAN bus system mit either USB or RS232, so that devices that are networked via CAN can be controlled by a PC with a simple serial connection (COM port) or with USB. The data transmission speed is then, of course, limited by the characterics of the serial connection and does not reach full CAN speed. For optimal performance and to use the full spectrum of CAN it is recommended to take a pure CAN solution. |
The analogue interface card (supported by the series PSI 9000 and PSI 8000) is parameterisable. That means, that the analogue and digital inputs/outputs can be configured to suit the needs of your application. For example, you can control the power supply by a system using the 0...5V range, while the device is using the common 0...10V range. The digital outputs can be used as alerting outputs for various errors like OT, OVP etc. Mor information in the user instruction guide. |
The digital interface card IF-G1 (GPIB/IEEE) differs from the other interface by using the standardised SCPI instruction set only. This enables simple integration of the device(s) into existing IEEE systems on one side, but also results in a reduced command list on the other side. The average data transmission speed of this card is very fast, the total command execution time lies at approx. 10-20ms, depending on the command used. |
The digital Ethernet card IF-E1B, used for the connection to common networks with 10/100Mbit, offers a DHCP and HTTP server, plus SCPI command language. The network card is almost auto-configuring and only requires three basic parameters for network access. An additional USB offers the complete functionality of a USB card of type IF-U1 (see above). The web interface provides the ability to access important device data like set values, actual values and status. A command line enables the user to remotely control the device (power supply or electronic load) via the network. This enables easy integration and creation of control and monitoring applications. |
There is another digital interface, the Profibus interface card IF-PB1. With this card the user can integrate supported power supply and electronic load series comfortably into a field bus network. It is compatible to DPV0 and DPV1, supports bus speeds of 9.6kBit/s...12MBit/s and up to 32 devices per bus segment. Identification of the units is done with included generic station device (GSD) files. |
