GE Fanuc IC660BBD021 Genius I/O Block Module Brand New

Product Overview

Part Number: IC660BBD021
Manufacturer: GE Fanuc
Product Type: Sink I/O Block
Series: Genius I/O (compatible with Series 90-30 PLCs)

Description

The IC660BBD021 is a 24/48 VDC Sink I/O Block featuring 16 discrete circuits, compatible with 3-wire sensors and electromechanical input devices. Each circuit can be configured as an input, tristate input, or output, offering versatile functionality for field automation and control systems.

This block receives 24/48 VDC field power from output devices and powers all 16 circuits internally—no external supply is required.

Key Features

• Versatile Circuit Configuration:

• Each of the 16 circuits can function as an input, tristate input, or output

• 3-Wire Sensor Compatibility

• Self-Powered Circuits: No additional external supply needed

• Advanced Diagnostics & Protection:

• Detects failed switches, open wires (in tristate mode), overloads, and no-load conditions

• Equipped with electronic short circuit and over-temperature protection

• Automatically shuts down to prevent overload damage

• Configurable Parameters:

• Output pulse testing

• Input filter timing

• Power-up output defaults

• Output behavior: hold last state or switch to default

Wiring & Installation

• Terminals Used: 6 to 21 (can be configured as inputs or outputs)

• Connection Requirements:

• Outputs connect to DC-

• Inputs connect to DC+

• No logic inversion required

• Tristate Input Wiring:

• Requires a resistor at the dry contact input to enable open wire diagnostics

• Grounding:

• A proper grounding system is required for safe and reliable operation

• Environmental Requirements:

• Install in a protective enclosure

• Avoid areas with airborne contaminants

• Ensure adequate ventilation and airflow

Maintenance & Safety

• Power Disconnection:

• Always disconnect both block power and circuit power before servicing

• Safety Warning:

• Touching field terminals while powered may result in electric shock

• Electronics Assembly Replacement:

1. Connect a Hand-held Monitor (HMM)

2. View and log circuit data

3. Power off and disconnect the block

4. Replace the electronics assembly safely
