GE FANUC IC660BBD025 5/12/24 VDC 32-Circuit Sink Block

Part Number IC660BBD025 Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockIC660BBD025 is a Sink I/O Block developed by GE Fanuc. It is a sophisticated, configurable 32-circuit Sink I/O Block from the GE Fanuc Genius I/O series. This module is designed to interface controllers with devices that send or receive binary signals, making it integral to various industrial automation systems. It supports both 2-wire and 3-wire proximity switches and other input devices, providing flexibility in system design. When current needs to be supplied to field output devices, the Source Block IC660BBD024 is recommended as an alternative. Features Operating with direct current (DC) in the 12 to 24 volts range, also supports +5 volt TTL (transistor-transistor logic) systems.

Its 32 circuits can be configured individually as inputs, outputs, or outputs with feedback, offering versatility in how the block is used within a system. The block's architecture includes protections for driver circuits against short circuits, which can occur due to wiring errors. Configurable features such as Output Pulse Test capability, Input Filter Time, and CPU Redundancy type enhance its adaptability to different applications. Installation and Connection Considerations It is designed with 42 terminals, numbered 5 through 46, for connecting field devices. Proper wiring of block power disconnects is crucial, as it ensures that both block power and input power can be simultaneously removed. This precaution prevents the block from powering up unexpectedly when multiple inputs are active. Installation requires a protective enclosure that shields the block from debris and moisture while ensuring adequate cooling and airflow. Additionally, grounding screws must be connected to a reliable grounding system to maintain safety and performance standards.

Diagnostic Capabilities and Monitoring It comes equipped with advanced diagnostics that monitor output status and check the actual switch state against expected or commanded conditions. The block can handle a steady-state load of 0.5 Amps under normal conditions, with diagnostic features such as short circuit protection, over-temperature shutdown, and switch state monitoring. These diagnostics ensure the block's reliable operation and are accessible via a handheld monitor or through the block built-in LEDs, providing real-time status updates. Power Specifications and Additional Features The block operates within nominal voltage ranges of 5 VDC, 12 VDC, and 24 VDC and provides block-to-block isolation with a voltage rating of 850 Volts. When 8 of its I/O points are in use as inputs, the block dissipates approximately 11 Watts of energy as heat, which increases to about 18 Watts when all 32 I/O points are active. Features multiple ports for enhanced connectivity, including Monitoring Port, Serial Port 1 and 2, and Shield In and Out Ports, all contributing to its flexibility in industrial settings.
