The Keithley 7056, Scanner Card, is a cost-effective and versatile solution to relay switching applications. Each channel of the card has two Form A (SPNO) contacts.
The switch may be wired for either 2-pole or 1-pole switching through the selection of the appropriate output. In 1-pole operation, channels HI and LO operate as independent, isolated inputs, thereby effectively doubling the number of input channels. With this card, even and odd numbered channels cannot be closed at the same time in the 20-channel mode.
