GE IC660BBD110 115V AC 16-Point Discrete Input Block

IC660BBD110 115V AC 16-Point Discrete Input Block

Product Introduction

The IC660BBD110 is a discrete input block from the GE Fanuc Genius series. It provides sixteen input points for connecting field devices like switches, limit switches, and pushbuttons. This block operates at a nominal 115 Volts AC with a frequency range of 47 to 63 Hz. Additionally, it supports both 2-wire and 3-wire proximity switch inputs. The IC660BBD110 communicates directly to the processor or communication adapter via the Genius protocol.

Technical Specifications

The IC660BBD110 has an operating voltage range of 93 to 132 VAC. Nominal input voltage is 115 VAC.

Key electrical parameters:

• Input current: 80 mA maximum block current plus 200 mA maximum input circuit current

• Number of points: Sixteen (16)

• Input on/off state: Programmable threshold from 25% to 85%

• Input shorted wire detection: Fixed 10%-90% thresholds

• Input response time: 1 ms plus configurable filter

• Input to ground or serial bus isolation: 1500V

• Selectable input filter times: 10 to 100 ms in 10 ms increments

Programmable Thresholds and Diagnostics

The IC660BBD110 offers programmable thresholds for both ON and OFF states. You can set these thresholds between 25% and 85% of the input voltage range. This flexibility allows precise matching to your specific field devices.

Internal channel diagnostics include:

• Open wire detection – programmable thresholds 25% to 85%

• Short circuit detection – fixed thresholds 10% to 90%

Fault reporting to the CPU can be enabled or disabled on a circuit-by-circuit basis. When fault reporting is disabled, diagnostic data still goes to the handheld monitor but not to the CPU.

LED Indicators and Status Reporting

LEDs on the IC660BBD110 work together with diagnostic software to alert you to several conditions:

• Failed switch

• Temperature above threshold levels

• Load exceeding design parameters

Specific LED behaviors:

• Input circuit LED ON – indicates threshold voltage has been reached

• I/O LED steady – shows the CPU is running and communicating

• Unit OK LED – confirms block health

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

Mechanical and Environmental Data

• Dimensions (H x W x D): 8.83 x 3.34 x 3.91 inches (22.44 x 8.48 x 9.93 cm)

• Weight: 4 lbs (1.8 kg)

• Operating Temperature: 0°C to 60°C (32°F to 140°F)

• Storage Temperature: -40°C to 100°C (-40°F to 212°F)

• Humidity: 5% to 95% non-condensing

Frequently Asked Questions (FAQ)

1. How many input points does the IC660BBD110 have?
The IC660BBD110 provides exactly sixteen (16) discrete input points. No output circuits are available on this model.

2. Can I program the input voltage thresholds?
Yes. You can program the ON and OFF thresholds from 25% to 85% of the input voltage range. This allows fine-tuning for different field devices.

3. What types of field devices work with this block?
The IC660BBD110 works with contact closures from switches, limit switches, and pushbuttons. It also supports 2-wire and 3-wire proximity switch inputs.

4. How do I enable or disable fault reporting for a specific circuit?
Fault reporting can be enabled or disabled on a circuit-by-circuit basis. When disabled, diagnostic data goes only to the handheld monitor, not to the CPU.

5. What is the isolation voltage rating?
Input to ground or serial bus isolation is 1500V. This provides excellent protection for your control system against voltage spikes.
