Product Overview

The Keithley 7056 is a 10-channel scanner card with electrical connection made through a quick disconnect screw terminal card (Model 7055). It is a cost-effective and versatile solution to relay switching applications. Each channel of the card has two Form A (SPNO) contacts. The switch can 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. In 20 channel mode, use as a one of 20 channel selector switch.
