Keithley 7169A Form C Switch Card

Each channel of the Model 7169A is a single post, twofold toss disengaged switch. There are two undedicated buses on the card that can be jumpered to interconnect channels or change the card arrangement from change to multiplex. Manufacturing plant introduced jumpers in arrangement with the Common terminal can be evacuated if a constraining resistor is required. All posts are accessible at the three 20-stick mass eliminators, which give snappy end and detach when utilizing Model 7169-MTC-3 Mass Terminated Cables or Model 7169-KIT connectors. Utilize just in Model 7002 centralized computer (relays are position sensitive). The scanner is utilized to associate numerous contributions to a solitary output in consecutive request. Just a single hand-off is shut whenever. In its most essential frame, transfer conclusion continues from the principal channel to the last. Some scanner frameworks have the ability to skip channels.

The grid switch design is the most adaptable in light of the fact that it can associate numerous contributions to various outputs. A grid is helpful when associations must be made between a few flag sources and a multiple gadget, such as a coordinated circuit or resistor. The confined, or free, switch setup comprises of individual transfers, frequently with numerous shafts, without any associations between transfers. In this outline, a solitary post ordinarily open transfer is controlling the association of the voltage source to the light. This hand-off associates one contribution to one output. A disengaged transfer can have more than one shaft and can have typically shut contacts and regularly open contacts.
