GE IC660BBA101 Genius Analog Input Block
Product Overview
The GE IC660BBA101 is a precision analog input block designed for GE’s Genius I/O series, serving as a critical component in industrial automation systems by converting continuous physical signals (such as temperature, pressure, and flow) from field sensors into digital data for PLC processing. As part of the Genius ecosystem, this module bridges the gap between analog sensors and control systems, enabling real-time monitoring and precise regulation of industrial processes.
Featuring 4 isolated analog input channels, the GE IC660BBA101 supports a range of input types, including 4–20 mA and 0–10 V DC, making it compatible with common industrial sensors like pressure transducers and thermocouple amplifiers. Its 2500 Vrms galvanic isolation between channels and the backplane protects sensitive control systems from voltage spikes and electromagnetic interference (EMI), ensuring signal integrity in electrically noisy environments such as factories with heavy machinery or motor drives.
In automation architectures, the IC660BBA101 integrates seamlessly with Genius bus controllers, communicating via the proprietary Genius bus to minimize latency. Its compact design allows installation in tight control cabinets, while rugged construction—including a metal housing and conformal coating—withstands extreme temperatures, vibration, and humidity. Though discontinued by GE, the GE IC660BBA101 remains vital for maintaining legacy systems in industries where upgrading to newer platforms is cost-prohibitive, ensuring operational continuity and reliable performance.

Main Features and Advantages
Precise analog signal conversion:
The IC660BBA101 delivers 12-bit resolution and ±0.1% full-scale accuracy, ensuring faithful reproduction of sensor signals—critical for applications like chemical reactor temperature control, where even small deviations can affect product quality. This precision allows PLCs to make fine adjustments to processes, optimizing efficiency and reducing waste.
Isolated channels:
With 2500 Vrms galvanic isolation between channels and the backplane, the module protects against ground loops, voltage transients, and EMI—common in facilities with welding equipment or variable frequency drives. This isolation prevents cross-talk between channels, ensuring stable readings from sensitive sensors like strain gauges or pH probes.
Flexible input compatibility:
Support for 4–20 mA (current loop) and 0–10 V DC (voltage) inputs adapts to diverse sensor types, eliminating the need for specialized converters. Whether connecting to a 4–20 mA flow meter or a 0–10 V DC level transmitter, the IC660BBA101 simplifies system design and reduces inventory complexity.
Rugged industrial design:
Rated for 0°C to 60°C operating temperatures and 5%–95% non-condensing humidity, the module thrives in harsh environments. Its metal housing and conformal coating resist dust, moisture, and vibration, making it suitable for food processing plants with washdowns, foundries with high ambient heat, or outdoor installations.
Seamless Genius integration:
Designed for the Genius I/O series, the IC660BBA101 communicates via the Genius bus, a high-speed network that connects distributed I/O blocks to PLCs. This integration enables centralized monitoring and configuration, with data transmitted to controllers like the IC693CPU363 with minimal latency.
Diagnostic capabilities:
Onboard diagnostics monitor sensor connections, signal integrity, and power status, alerting operators to faults (e.g., open circuits, overrange signals) via front-panel LEDs and system logs. This proactive fault detection reduces mean time to repair (MTTR), minimizing unplanned downtime in critical processes.
Application Areas
The GE IC660BBA101 excels in industries requiring precise analog signal monitoring:
- Manufacturing:
Monitors temperature in plastic extrusion lines, pressure in hydraulic presses, and flow rates in material blending systems. Its accuracy ensures consistent product quality, from automotive part dimensions to packaging film thickness. - Energy Sector:
Measures steam pressure in boiler systems, turbine bearing temperatures, and fuel flow rates in power plants. Reliable signal conversion supports efficient energy production and compliance with grid stability standards. - Chemical Processing:
Tracks reactor vessel pressure, chemical concentration, and jacket temperature in batch processing. Isolation features protect against corrosive environment-induced electrical noise, ensuring safe operation. - Water and Wastewater:
Converts signals from level transmitters in treatment tanks, pH sensors in filtration systems, and flow meters in distribution pipelines. Its rugged design withstands wet, chemically exposed environments.
Specific applications include regulating temperature in pharmaceutical reactors, monitoring pressure in natural gas pipelines, and controlling flow in beverage bottling lines.

Installation and Maintenance
Pre-installation preparations:
Ensure the mounting surface (DIN rail or panel) is clean, grounded, and within the 0°C to 60°C operating range. Verify compatibility with the Genius bus controller (e.g., IC693BEM331) and sensor types (4–20 mA or 0–10 V DC). Connect shielded twisted-pair cables from sensors to the module’s terminals, routing them away from high-voltage lines to minimize EMI. Apply 24 V DC power (via IC693PWR321) and configure input ranges using GE’s Genius Configuration Software to match sensor specifications.
Maintenance suggestions:
Perform quarterly visual inspections to check for loose connections or damaged cables. Calibrate the IC660BBA101 annually using a precision signal generator to maintain ±0.1% accuracy—critical for regulated industries like pharmaceuticals. Clean dust from vents biannually with compressed air, especially in dusty environments like cement plants. Monitor diagnostic LEDs for fault indicators (e.g., red for overrange) and address issues promptly. Store spare IC660BBA101 modules in anti-static packaging at 10–30°C with <60% humidity, testing calibration yearly to ensure readiness.
