The GE-Emerson IC660BBD025 Genius Sink I/O Block receives current from field output devices. The block is a configurable module that interfaces the controller to devices that provide or accept a binary signal. The block is compatible with 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 32 identical discrete I/O circuits, each easily configured to be an input, an output, or an output with feedback. 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.
Block LEDs verify proper block operation and CPU communications. Individual circuit LEDs on the logic side indicate the voltage present on inputs and outputs.
