NEW BERLIN, Wis., July 26, 2004 — Digalog Systems Inc. of New Berlin, WI, has announced the addition of a new card to its lineup of PXI switching resources. The 32-Channel Discrete Switching Card (part number 0000-6622) occupies a single 3U slot and is aimed at test applications where unit-under-test response to leaky and dirty input switch contacts must be verified.
The board is organized as four banks of eight channels. Each bank can be connected to a separate external voltage source of up to +/-20V, and each channel of that bank can be connected to that voltage through either a 47-ohm resistor for "dirty closed switch" simulation, or to a 51kOhm resistor to simulate a "leaky open switch" condition. Individual channel current is limited to 40mA.
Software provided with the card allows all channels to be controlled with functional calls in standard programming languages, either manually or through a pre-programmed state scan list. The associated Scan Advance Output trigger signal can be routed through the standard PXI trigger lines to signal other PXI cards. Its default wait time of 1ms after switching can be extended using the ConfigureScanTrigger functional call.
The 0000-6622 32-Channel Discrete Switch Card can be ordered from Digalog’s PXI website at . Further information is available on the site or by contacting Rick Wagner at 262-797-8000.
