IC660BBD120 High Speed Counter Block from GE Fanuc
The IC660BBD120 belongs to the GE Fanuc Genius I/O series. GE Fanuc designed this block for high-speed industrial tasks. It processes up to 200 kHz input frequency. You can use it for motion control, material handling, and velocity measurement. Additionally, it supports turbine flowmeter applications with great accuracy.
Key Technical Specifications
This module includes 12 discrete inputs. Their voltage range runs from 5V DC to 30V DC. You also get 4 discrete outputs. Each output delivers 4.75V to 5.25V DC at 200 mA. This voltage range is a critical specification for stable operation. The oscillator output provides 3.8V at 4.0 mA. Furthermore, a dedicated 5V DC output supplies 0.5 A.
The IC660BBD120 supports multiple counting modes. You can configure it to count up, count down, or both. It also calculates the difference between two changing values. When the accumulated count reaches preset thresholds, outputs turn ON or OFF automatically. This direct processing feature removes the need for constant CPU communication.
Power and Voltage Details
You can power the IC660BBD120 using a 115 VAC source. Alternatively, a 10-30 VDC source works as well. The module also accepts simultaneous AC and DC power. If the 115 VAC fails, the block continues running on DC power. Its rated voltage spans 93 to 132 VAC or 10-30 VDC. Input voltage range sits between 5V and 30V DC. The output voltage range stays stable at 4.75V to 5.25V DC.
Filter Delays and Frequency Response
Two filter options are available. The high-frequency filter introduces a delay of only 2.5 µs. This setting allows a maximum count rate of 200 kHz. The low-frequency filter gives a 12.5 ms delay. Its maximum count rate is 40 Hz. For input pulse width, the high-frequency filter needs at least 2.5 µs. The low-frequency filter requires 12.5 ms minimum. Therefore, you can match the module to either fast or slow signal sources.
Environmental and Mechanical Ratings
The IC660BBD120 operates between 0°C and 60°C. This range covers most industrial environments. Store it safely from -40°C to 100°C. Humidity tolerance reaches 5-95% non-condensing. Operating vibration ranges from 5-10 Hz with a 2” displacement. The module measures 8.83” x 3.50” x 3.94” (HxWxD). This compact size fits into most industrial enclosures.
Installation and Mounting Guidelines
This open-type module needs a protective enclosure. Industrial contaminants must stay away from the unit. The design has two separate parts. First, the terminal base assembly (part IC660TBD120) holds all wire connections. Second, the electronics assembly (part IC660EBD120) snaps onto the base. This modular structure lets you replace electronics without disconnecting wires. Mount the block using its built-in holes. No rack or backplane is required.
Moreover, you can connect the IC660BBD120 directly to a Genius I/O network. A dedicated port allows Hand-Held Monitor (HHM) connection. Use the HHM for local configuration and diagnostics. The top LEDs show unit status and communication status with the CPU. Four bottom LEDs display each output's ON/OFF condition.
How the Direct Processing Mode Works
The IC660BBD120 does not rely on a CPU during normal operations. It automatically detects input signals and counts them. Then it sends outputs based on preset values. For example, you can program an output to activate when the counter reaches 10,000 pulses. This feature works perfectly for batching or cut-to-length applications. Furthermore, the module supports battery backup. This keeps the count value safe during power loss.
Application Examples
You will find the IC660BBD120 in many industries. Turbine flowmeters rely on its high-speed input. Meter proving systems use its precise counting. Velocity measurement applications benefit from the 200 kHz rate. Material handling lines use it for position tracking. Motion control systems depend on its fast response. Each output can handle 3 Amps inrush current for up to 10 milliseconds. This makes the module robust for driving small solenoids or indicators.

FAQ
Can the IC660BBD120 work without a PLC CPU?
Yes, it uses direct processing mode. It counts inputs and controls outputs independently without CPU communication.
What happens if the 115V AC power fails?
The module keeps running on the DC power source. Both AC and DC can be connected simultaneously for redundancy.
How do I change the counting direction on this module?
You configure it via software or a Hand-Held Monitor. Options include up only, down only, up/down, or differential counting.
What is the maximum input frequency for the IC660BBD120?
With the high-frequency filter selected, it accepts up to 200 kHz. The low-frequency filter limits input to 40 Hz.
