A 10-channel scanner containing eight relay inputs and two solid-state inputs. Multiplex one of ten 2-pole or one of five 4-pole signals into the Model 2000, 2001, 2002, or 2010 DMM and/or any combination of 2- or 4-pole signals. Two solid-state channels offer high-speed multiplexing on the Model 2001 and 2002.

GENERAL
10 CHANNELS: 8 channels of 2-pole relay input.
