GE IC660BBD020 DC Discrete I/O Modules
Genius I/O Industrial I/OGenius DC Discrete I/O blocks interface to a wide range of input devices, including both 2–wire and 3–
wire electronic proximity switches. Outputs may be low–power control and indicating devices such as
relays, contactors, and lamps. These blocks have identical discrete I/O circuits, each easily configured to
be an input or an output. Output circuits can be directly connected to input circuits without the use of
other components or inversion of logic states. This flexibility provides maximum design and application
efficiency. Each circuit contains built–in protection when used as an output, protecting the driver while
allowing short–time surges. It also protects against shorted loads caused by wiring errors.
