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