GE IC660BBD020 24/48V Source I/O 16 Circuit Block

GE IC660BBD020 Genius I/O Block

Product Introduction

The IC660BBD020 operates as a flexible Source I/O block within the GE Genius I/O series. GE Fanuc originally manufactured this module for the Series 90-30 PLC system. It supports 16 discrete circuits, each independently set as input, output, or tristate input. You can use it with 3-wire solid-state sensors or electromechanical relays. Additionally, this block provides diagnostic features like short circuit and over-temperature detection. Its Genius protocol ensures reliable communication with the controller.

Key Technical Specifications

The IC660BBD020 runs on a nominal voltage of 24 VDC or 48 VDC. Its operating voltage range spans from 18 to 56 VDC. Each circuit handles a load current up to 2 Amperes. The input response time measures 1.7 milliseconds, plus a configurable filter from 5 to 100 milliseconds. Output response time is only 1.0 millisecond.

For input impedance, the block delivers 5.6 kOhms at 24-48 VDC and 1.8 kOhms at 24 VDC. Block-to-block isolation reaches 1500V for one minute. The module uses the Genius communication protocol and includes Unit OK and I/O Enabled LEDs.

Configuration and Circuit Features

Each of the 16 circuits on the IC660BBD020 is independently configurable. You can set a circuit as a standard input, a tristate input, or an output. Tristate inputs allow open wire detection. Moreover, the filter time is software-selectable between 10 ms and 100 ms. This flexibility makes the block suitable for mixed I/O applications. For output, the block supports pulse test, power-up default, and last state hold functions.

Diagnostic Capabilities

The IC660BBD020 includes powerful internal diagnostics. It detects installation problems and runtime errors. Specifically, it monitors for short circuits, over-temperature, failed switch conditions, open wires, overload, and no-load situations. When an error occurs, the block reports it to a handheld monitor and takes corrective action. This feature reduces downtime and simplifies troubleshooting.

Compatibility and Assembly Requirements

This module works with Terminal Assembly IC660TSD020 version C or later. However, it is not compatible with IC660ELD020 or IC660EBD020 versions A to E. Nevertheless, those assemblies can receive an upgrade to work with the IC660BBD020. Most handheld monitors work with this block, except the IC660HHM501, which needs some configuration. The block connects via a Genius bus and requires terminating resistors on the first and last nodes.

Mechanical and Environmental Parameters

The IC660BBD020 measures 8.83 inches (22.44 cm) in height, 3.50 inches (8.89 cm) in width, and 3.94 inches (10.00 cm) in depth. It operates within a temperature range of 0 to 60 degrees Celsius. For reliable operation, install it in a clean area free of airborne contaminants. Adequate cooling airflow is necessary. You can mount the block right-side up or upside down. However, grounding is critical. Use a short wire lead and the mounting screws with star washers to ensure a reliable ground system.

Installation Guidelines

First, ensure the installation area has no EMC noise or heat-generating devices. Next, mount the block securely using the provided screws. Connect the Genius bus by daisy-chaining to other blocks or directly to the master controller. Furthermore, attach terminating resistors across serial 1 and serial 2 terminals on the first and last nodes. For field wiring, use the 22 connection terminals. These accommodate power, signal wiring, and bus connectivity. Finally, verify that the terminal assembly version is C or later.

Frequently Asked Questions (FAQ)

1. Can the IC660BBD020 work with 3-wire sensors?
Yes, the IC660BBD020 is specifically compatible with 3-wire solid-state and electromechanical sensors. Each circuit supports this wiring type.

2. What happens if a short circuit occurs?
The block detects the short circuit immediately. It then reports the error to the handheld monitor and takes corrective action, such as shutting down the affected circuit.

3. Is this module compatible with older IC660EBD020 assemblies?
No, it is not compatible with IC660EBD020 versions A to E. However, you can upgrade those assemblies to work with the IC660BBD020.

4. What is the maximum load current per circuit?
Each circuit on the IC660BBD020 handles a load current of up to 2 Amperes. The total depends on your configuration and cooling.

5. Do I need a special handheld monitor to configure this block?
Most handheld monitors work fine. Only the IC660HHM501 requires additional configuration. Other models work without changes.
