GE IC660BBD101 115 VAC 8-Circuit Low Leakage I/O Block

IC660BBD101 115 VAC 8-Circuit Low Leakage I/O Block

Product Introduction

The IC660BBD101 belongs to the GE Fanuc Genius I/O series, now under Emerson Automation. This discrete I/O block provides eight identical circuits. Each circuit is independently configurable as an input or output. The block operates at a nominal 115 Volts AC with a frequency range of 47 to 63 Hz. It links multiple discrete sensors and actuators to a communication bus. Moreover, it accommodates high input impedance without needing a separate power supply.

Technical Specifications

The IC660BBD101 has an operating voltage range of 93 to 132 VAC. Nominal voltage is 115 VAC. Frequency rating is 47 to 63 Hertz.

Key electrical parameters:

• Steady-state output current: 2 Amps per circuit

• Maximum inrush current: 25 Amps peak up to 2 cycles

• Maximum block output current: 15 Amps at 35°C, 7.5 Amps at 60°C

• Input response time: 2 ms plus configurable filter

• Output response time: Zero crossing

• Block-to-block isolation: 1500V for one minute

• Heat dissipation: 43.5 Watts maximum

Protection and Fuse Features

The IC660BBD101 includes electronic fuse protection for all eight circuits. A fuse shuts down output current if it exceeds 30 Amps when the output turns on. It also trips if current exceeds 20 Amps after two cycles. Shutdown happens within 5 milliseconds.

Once tripped, you can restore the circuit by issuing a command from the CPU or a handheld monitor. This resettable protection prevents damage from wiring errors or overloads.

Configurable Features

The IC660BBD101 offers several user-configurable options:

• Input filter times: Selectable from 10 ms to 100 ms in 10 ms increments

• Output Pulse Test capability for all outputs

• Output feedback for voltage monitoring

• Module control for bus switching

• Default settings for output power-up

Diagnostics and LED Indicators

The IC660BBD101 comes with advanced self-diagnostics. Input channels can detect:

• Open wire conditions

• Overtemperature errors

• Failed switch states

Output diagnostics include:

• Short circuit detection

• Overload conditions

• No load detection

• Failed switch

• Overtemperature

LED indicators provide clear visual feedback:

• Unit OK – shows block health

• I/O Enabled – indicates active I/O operations

• One dedicated LED per circuit – for input circuits, ON means the terminal reached threshold voltage; for output circuits, ON means the circuit complied with the CPU command

Error messages also appear on a handheld monitor, helping you attend to faults promptly.

Frequently Asked Questions (FAQ)

1. Does the IC660BBD101 need a separate power supply?
No. The IC660BBD101 draws its control power directly from the I/O device voltages wired to the terminals.

2. How do I restore a circuit after the fuse trips?
The electronic fuse shuts down automatically when current exceeds limits. Send a command from the CPU or a handheld monitor to restore the circuit.

3. What filter times can I select for inputs?
You can select input filter times from 10 ms to 100 ms in 10 ms increments. This helps debounce noisy signals.

4. Can I mount this block upside down?
Yes. The IC660BBD101 can be mounted right-side up or upside down. Just ensure adequate cooling airflow around the enclosure.

5. What does the dedicated LED indicate on an output circuit?
For an output circuit, an ON LED means that circuit has complied with the command issued by the CPU. For inputs, ON means the terminal reached the threshold voltage.
