Part Number: IC660BBD021
The IC660BBD021 is a 24/48 VDC Sink I/O module designed for use with GE Fanuc's Series 90-30 PLCs, featuring 16 discrete circuits compatible with both electromechanical and 3-wire solid sensors. This module operates on a voltage range of 24/48 VDC provided from field output devices, eliminating the need for an additional power supply for circuit functionality. Each of the 16 circuits can be configured as inputs, tristate inputs, or outputs, with versatile parameters such as output pulse testing, input filter time adjustments, and output defaults, including hold last state capabilities.

Engineered for reliability, the IC660BBD021 includes built-in electronic short circuit and over-temperature protection, which safeguards against potential failure conditions such as switch malfunctions, open wires in tristate inputs, and overloads. Adequate preventive measures maintain the integrity of the module in overload situations by initiating a shutdown. Installation should be in a protective enclosure that allows for sufficient airflow and prevents airborne contaminants.

The module requires a grounding system and utilizes terminals 6 to 21 for interfacing, allowing for functional operation without logic inversion when connecting outputs to DC- and inputs to DC+. Tristate input functionality necessitates the addition of a resistor on the dry contacts to ensure open wire diagnostics. Precautions must be taken during power disconnection; specifically, circuit power must be disengaged before block power is turned off to mitigate electrical hazards. For any electronics assembly replacement, initial connection to a handheld monitor is required to assess circuit conditions prior to power down and disassembly.

Technical Specifications include a rated voltage of 24/48 VDC, an input range of 18-56 VDC, and a load current capacity of 2 Amps across a single common grouping of 16 points.
