Description
Product Introduction & Engineering Value
When a process requires both measurement and control at a remote field location, separate analog input and output modules increase wiring complexity and cabinet space. The GE IC660BBA100 combines both functions into a single Genius I/O block, reducing installation effort while maintaining fast analog signal updates.
Designed for the GE Genius distributed I/O platform, the module supports multiple voltage and current signal ranges, making it suitable for integrating transmitters, control valves, variable-speed drives, and other analog devices into Series 90-30, Series 90-70, and compatible Genius-based automation systems.

Field Application & The “Trench” Experience
A wastewater treatment plant experienced unstable chlorine dosing because analog inputs from chemical analyzers and outputs to metering pumps were distributed across multiple control panels. During a modernization project, technicians replaced the remote hardware with an IC660BBA100 Genius Analog I/O Block. The combined analog inputs and outputs reduced field wiring, simplified troubleshooting, and restored stable dosing control without modifying the PLC application.
Typical applications include:
- Chemical dosing systems in water treatment plants
- Steam pressure control in utility boiler houses
- Tank level measurement with proportional valve control
Transparency SOP: QA & Testing
Every New Surplus or Refurbished IC660BBA100 undergoes a documented inspection procedure before shipment.
- Verify the complete catalog number and hardware revision.
- Inspect the terminal assembly, enclosure, and Genius communication connector.
- Test all four analog input channels using calibrated voltage and current sources.
- Verify both analog outputs across supported signal ranges.
- Confirm LED operation, communication status, and internal diagnostics.
- Inspect isolation circuitry and power supply components.
- Package the module in anti-static materials with impact-resistant protection.

The Veteran’s Tech Trap Guide
⚠️ Check the Supply Voltage Before Ordering
The IC660BBA100 is the 115 VAC powered version. GE also produced 24/48 VDC variants with similar model numbers. Ordering the wrong supply voltage can prevent the block from operating correctly.
⚠️ Configure Each Channel Individually
Each analog channel supports multiple voltage and current ranges. Verify every channel configuration during commissioning, especially when replacing an existing block with mixed transmitter types. Incorrect scaling often appears as a failed instrument when the hardware is functioning normally.
PRO TIP: If communication with the Genius Bus is interrupted, configure output channels to either hold the last value or return to a predefined default based on the process safety requirements. This setting should be reviewed before startup rather than after a network fault occurs.
Dynamic FAQ
Q1. What is the primary function of the IC660BBA100?
The combines four analog input channels and two analog output channels into a single Genius I/O block for distributed industrial control systems.
Q2. Which analog signal ranges are supported?
The block supports 0–10 VDC, ±10 VDC, ±5 VDC, 0–5 VDC, 4–20 mA, and optional 1–5 VDC operation through software configuration.
Q3. Which PLC platforms are compatible with this module?
The is designed for the GE Genius I/O architecture and is commonly used with Series 90-30, Series 90-70, and other Genius-compatible GE controllers.
Q4. Can each channel use a different signal type?
Yes. Individual channels can be configured and scaled independently, allowing a mix of voltage and current devices within the same I/O block.
Q5. How are refurbished units tested?
Each unit undergoes model verification, analog calibration checks, communication testing, power supply verification, isolation inspection, and functional I/O testing before shipment.
Q6. Are New Surplus units still available?
Yes. Depending on inventory, New Surplus and professionally Refurbished modules are available with warranty support for legacy Genius I/O installations.
