GE IC660BBD025 Sink I/O Block 32-Circuit

IC660BBD025 5/12/24 VDC 32-Circuit Sink I/O Block

Product Introduction

The IC660BBD025 is a flexible sink I/O block designed for distributed control systems. It connects controllers to field devices like proximity switches and sensors. This module supports both 2-wire and 3-wire devices. Additionally, it works with +5 volt TTL logic. You can configure each of its 32 circuits as input, output, or output with feedback.

Technical Specifications

The IC660BBD025 accepts input signals at 5, 12, or 24 VDC. Input processing time is 1.4 ms. Outputs handle a steady-state load of 0.5 Amperes per circuit. Maximum inrush current reaches 4 Amperes for up to 10 ms.

Block-to-block isolation is rated at 850 Volts. Heat dissipation measures 11 Watts with 8 inputs active and 18 Watts with all 32 inputs on. The module also includes resettable self-protecting circuits.

Key features include:

• Output Pulse Test capability

• Selectable Input Filter Time (1 to 100 ms)

• CPU Redundancy support

• Output Hold behavior configuration

• Ready for Bus Switching Module control

Mechanical and Environmental Data

• Dimensions (H x W x D): 8.83 x 3.58 x 4.7 inches

• Operating Temperature: 0°C to 60°C

• Storage Temperature: -40°C to 100°C

• Humidity: 5-95% non-condensing

• Compatible terminal base: IC660TBD025

• Compatible electronics assembly: IC660EBD025

Installation Guidelines

For proper installation, use a protective case. Choose a location free of airborne contaminants. Ensure adequate cooling and airflow around the block.

Ground screws must connect to a reliable grounding system. Wire the block power disconnects so block power and input power remove at the same time. This prevents unexpected power-up when multiple inputs are active.

Terminals 5 through 46 are for field device connections. Furthermore, you can configure the IC660BBD025 using a handheld monitor. The monitor also works with onboard LEDs to check status quickly.

Built-In Diagnostics and Protection

The IC660BBD025 ships with block diagnostics that monitor output and compare actual switch state to the commanded state. Output diagnostics include failed switch detection.

Short circuits caused by wiring errors are protected at the driver circuit level. Overload and overtemperature protection are also integrated.

Why Choose This Module?

This Genius I/O block supports remote installation up to 7500 feet from the controller. It integrates directly with Series 90-30 and Series 90-70 controllers. Third-party devices supporting the Genius protocol also work with it.

Moreover, the IC660BBD025 provides LED indicators for Module OK and I/O Enabled. Individual LEDs light up when each I/O point is used.

Frequently Asked Questions (FAQ)

1. Can the IC660BBD025 work as both input and output on different circuits?
Yes. Each of the 32 circuits is independently configurable as input, output, or output with feedback.

2. What happens if a field output device needs to supply current instead of receiving it?
For sourcing current to field devices, use the IC660BBD024 source block instead of the IC660BBD025.

3. Is the IC660BBD025 compatible with TTL signals?
Absolutely. It supports +5 volt TTL logic, making it ideal for digital systems.

4. How do I configure the input filter time?
Use a handheld monitor connected to the block. Selectable filter times range from 1 ms to 100 ms.

5. Can I use this block with a redundant CPU setup?
Yes. The IC660BBD025 includes CPU Redundancy type as a configurable feature.
