The Model 7707 plug-in module offers 10 channels of 2-pole or 5 channels of 4-pole multiplexer switching that can be configured as two
independent banks of multiplexers. The Model
7707 also provides 32 digital input/output channels (four 8-bit ports) for I/O control. Connect
the Model 7707 to industry standard solid-state
relays to switch up to 980VA.
