The Keithley 7018-S Dual 1x10 Multiplexer Card w/Screw Terminal Connector Board is a 28-channel multiplexer with two independent banks of 1x14 switching. Each channel is 3-pole. The two banks can be combined for a variety of different switching configurations. Used separately, they provide a dual 1x14 3-pole configuration. Onboard jumpers can connect the outputs together for a single 1x28 3-pole arrangement. Both the 7001 and 7002 switch systems can use the two banks in parallel for 6-pole operation in a 1x14 configuration.
