GE IC660BBD022 24V Source I/O 16 Circuit Block

GE IC660BBD022 Genius I/O Block

Product Introduction

The IC660BBD022 functions as a Source I/O block within the GE Genius I/O series. GE Fanuc originally designed this module for the Series 90-30 PLC system. It supports 16 discrete circuits, and you can configure each one independently as an input, output, or tristate input. This block works seamlessly with 2-wire and 3-wire solid-state sensors as well as electromechanical sensors. Moreover, it provides comprehensive diagnostic features including short circuit, over-temperature, and open wire detection. The Genius protocol ensures reliable communication with the master controller.

Key Technical Specifications

The IC660BBD022 operates on a nominal voltage of 24 VDC, with an operating range of 18 to 30 VDC. Each circuit delivers a steady-state output current up to 2 Amperes. The maximum inrush current reaches 10 Amperes for up to 10 milliseconds. Input processing time measures 1.7 milliseconds, plus any delay from the selected input filter. The output turn-on delay is only 1.0 millisecond, and the output response time also equals 1.0 millisecond.

For isolation, the block provides 1500 Volts block-to-block. The maximum ripple is 10%. Maximum switching frequency is once per second. The module includes Unit OK and I/O Enabled LEDs on the front panel. Heat dissipation reaches 68.8 Watts when operating at 2 Amperes.

Input and Output Characteristics

Input channels on the IC660BBD022 accept nominal voltages of 24 VDC or 48 VDC. The configurable filter time ranges from 5 to 100 milliseconds. Output circuits feature a maximum turn-on delay of 1 millisecond. The block uses terminals 6 through 21 for the 16 circuits. Terminals interface with #12 wire or two #14 wires. DC power connects to terminals 5 and 22. The serial bus uses terminals 1 through 4.

Tristate Input and Configuration Features

Using a terminal as a tristate input on the IC660BBD022 enables open wire diagnostic capabilities. The block powers all circuits internally, so no separate supply is necessary for field devices. Configurable parameters include output pulse test capability, selectable input filter time, output power-up defaults, and output hold last state or default. These features give you excellent flexibility for various application requirements.

Diagnostic and Protection Features

The IC660BBD022 includes extensive diagnostic and protective capabilities. It monitors for electronic short circuits, over-temperature, failed switch conditions, open wires (on tristate inputs), overload, and no-load situations. When the block detects an overload, it shuts down automatically to prevent damage. The block reports all errors to a handheld monitor and takes appropriate corrective action. These features significantly reduce troubleshooting time and improve system reliability.

Compatibility and Assembly Requirements

The IC660BBD022 can replace all its previous versions when you connect a compatible electronics assembly. This module consists of two main components. The electronics assembly is IC660EBD021, and the terminal base assembly is IC660TSD021. These two parts work together to form the complete I/O block. The module connects to a Genius bus network as a single distributed I/O node. It also includes a port for Hand-Held Monitor (HHM) communication, allowing local monitoring and configuration.

Mechanical and Environmental Parameters

The IC660BBD022 measures 8.83 inches (22.44 cm) in height, 3.56 inches (9.04 cm) in width, and 4.42 inches (11.23 cm) in depth. It weighs approximately 4 pounds (1.81 kg). The operating temperature range is 0 to 60 degrees Celsius. Storage temperature spans from -40 to 100 degrees Celsius. Humidity tolerance is 5% to 95% non-condensing.

Installation Guidelines

First, install the IC660BBD022 inside a protective enclosure. The installation area must be clean and free from airborne contaminants. Adequate airflow is essential for proper cooling. You can mount the block right-side up or upside down. However, grounding is critical. Use a short wire lead and a reliable grounding system.

When replacing an electronics assembly, exercise extreme caution due to the danger of electrical shock. Before disconnecting block power, always disconnect circuit power first. To replace an electronics assembly, first connect a handheld monitor. Monitor the circuits from the HHM menu, then turn it off and disconnect. Power down the block, remove the old electronics assembly, and install the new one.

Frequently Asked Questions (FAQ)

1. Can the IC660BBD022 work with 2-wire sensors?
Yes, the IC660BBD022 is specifically compatible with both 2-wire and 3-wire solid-state sensors. Each circuit supports these wiring types without needing additional components.

2. What is the operating voltage range for this block?
The IC660BBD022 operates at a nominal 24 VDC with an acceptable range of 18 to 30 VDC. This differs from the IC660BBD020 which accepts 24/48 VDC.

3. How do I enable open wire detection on a tristate input?
For the IC660BBD022, you can enable open wire detection by configuring the circuit as a tristate input. The block then automatically monitors for open wire conditions.

4. What happens during an overload condition?
The IC660BBD022 detects the overload immediately. Its protective mechanism shuts down the affected circuit to prevent damage. The block also reports the error to the handheld monitor.

5. Is the IC660BBD022 compatible with IC660TSD020 or IC660TSD021?
The IC660BBD022 requires the IC660TSD021 terminal base assembly. Always verify your assembly version matches the compatible components listed in the specifications.
