GE Fanuc IC660BBD024 12/24 VDC Source I/O Block

IC660BBD024 32-Circuit Source I/O Block

Product Introduction

The IC660BBD024 belongs to the GE Fanuc Genius I/O family. It is a flexible and intelligent block for industrial control systems. This module provides current to field output devices like proximity switches, relays, and lamps. Specifically, it supports both 2-wire and 3-wire configurations.

Each of the 32 discrete circuits can be configured individually. For example, you can set some as inputs, others as outputs, and a few as outputs with feedback. Additionally, the circuits include self-protection features. The block software protects the driver against short circuits caused by wiring errors. It also allows short-duration surges without damage.

Another key advantage is that calibration is not required. The manufacturer performs this step. However, configuration must be done by the user. You can use a handheld monitor or send a Write Configuration datagram from the host controller.

Technical Specifications

The IC660BBD024 operates with a supply voltage of 12 or 24 VDC. Its input impedance is 3.3k Ohms. Typical input processing time reaches 1.4 ms, plus a selectable filter delay.

You can choose from many input filter options. These include 1, 2, 3, 4, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100 ms.

When used as an output, each channel delivers 0.5 Amps continuously. Maximum inrush current reaches 4 Amps for up to 10 ms. This inrush can repeat once every 0.5 seconds. The total block output current is 16 Amps. Output turn-on delay is only 0.5 ms maximum.

Moreover, this module includes output diagnostics. It detects switch faults automatically. The block-to-block isolation rating is 850 Volts.

Communication and Compatibility

The IC660BBD024 uses the Genius Bus protocol. It works with bus controllers like the IC660CBB902 or IC660CBB903. Additionally, models IC660CBB900 or IC660CBB901 (version 1.3 or later) are compatible. For configuration, you can use the handheld monitor IC660HHM501.

If you need a Bus Switching Module (BSM), the IC660BSM021 is the recommended partner device.

Input and Output Characteristics

For input signals at 12 VDC, the ON-state range is 8–12 VDC. At 24 VDC, the ON-state range is 18–24 VDC. The module also includes a TTL level of 5 Volts.

Output channels have a maximum voltage drop of 2.0 volts at 4 Amps inrush. This ensures stable operation during high-current events.

Power and Environmental Ratings

Power supply dropout is 4 ms at 12 Volts and 20 ms at 24 Volts. Maximum ripple is 10% for 12–24 VDC and 1% for 5 VDC.

The operating temperature range is 0 to 60 degrees Celsius. Humidity can reach up to 95% non-condensing.

Mechanical and Mounting Information

The IC660BBD024 comes in an open enclosure. Therefore, you must install it inside a protective cabinet. This prevents exposure to dust, moisture, or airborne contaminants.

Mounting orientation is flexible. You can install it right-side up or upside down. However, always leave at least 2 inches of space between adjacent blocks. This spacing ensures proper cooling and easy access.

Additionally, you can replace the electronics assembly without removing field wiring. This is possible as long as the replacement assembly comes from a compatible block model. No reconfiguration is needed after replacement.

Installation Guide

Follow these steps to install the IC660BBD024 correctly.

1. Turn off all power to the system before handling the block.

2. Mount the block securely inside a grounded enclosure. Use the provided mounting holes.

3. Leave adequate space (minimum 2 inches) between blocks for ventilation.

4. Connect field wiring to the terminal blocks. Follow the source wiring diagram.

5. Set the block address and configuration using a handheld monitor or datagram.

6. Apply power and verify LED indications. Each active channel lights a corresponding LED.

7. Test each circuit as input or output before full system operation.

Remember that calibration is factory-performed. Only configuration is user-defined.

Frequently Asked Questions (FAQ)

1. Can I mix input and output circuits on the same IC660BBD024 block?
Yes. Each of the 32 circuits is individually configurable. You can set some as inputs, some as outputs, and others as outputs with feedback on the same module.

2. What happens if an output channel is shorted?
The block software protects the driver automatically. It guards against shorted electrical loads caused by wiring errors. Short-duration surges are allowed, but persistent faults will trigger diagnostics.

3. Do I need to calibrate the IC660BBD024 after installation?
No. Calibration is performed by the manufacturer. You only need to configure the block for your specific application.

4. Which handheld monitor works with this module?
Use the IC660HHM501 Hand-Held Monitor. Alternatively, you can send a Write Configuration datagram from the host controller if a monitor is not available.

5. Can I use the IC660BBD024 as a Bus Switching Module (BSM) controller?
Yes. This block can function as a BSM controller when needed. For BSM applications, pair it with the IC660BSM021 module.
