                                    The Model 7056 Is a general purpose relay scanner plug-in
card which is field-installable in an appropriate Kelthley
scanner mainframe (e.g. Model 705). The Model 7056 will
switch up to 10 channels. The card can be used as a voltage
scanner, independent relay card or a matrix card. The 2-pole
switching Is accomplished in less than 2ms and the expected
relay life is 106 closures at the maximum contact ratings.
Barrier strips are used to facilitate input and output
connections to the relay scanner plug-in card. The plug-in
card can easily be removed through the rear panel of the
scanner mainframe. The Model 7055 provides the connection to
the individual channels via the screw clamp type terminal
strips.
