It weighs approximately 2 pounds and operates on 24/48 Volts DC power.

Technical Specifications Breakdown

Key parameters for the IC660TBA021 are listed below for quick reference:

Industry Applications

The IC660TBA021 terminal assembly is primarily used in temperature monitoring applications within programmable logic controller (PLC) systems. Its 6-channel RTD input block supports two circuits per group, making it suitable for distributed temperature sensing in industrial processes such as chemical reactors, HVAC systems, and manufacturing lines. The ability to configure alarm thresholds and input filter time settings allows operators to fine-tune performance for specific process requirements. The automatic diagnostics feature reduces downtime by quickly identifying open wire, wiring error, input short detection, underrange, and overrange conditions.

Installation & Setup Guidance

When installing this terminal assembly, ensure the power supply matches the 24/48 Volts DC rating. The block provides four terminals per channel: SIG, RTN, SHLD, and REF for wiring input devices. Use the shield terminal to suppress noise on individual circuits, especially in environments where electrical noise may exceed 4000 Volts. The multiplexer switch inside the block facilitates self-calibration by converting between the RTD input and internal reference resistors. Verify that the operating environment stays within 0 to 60 degrees Celsius during operation.

Maintenance & Reliability

Regular inspection of the terminal assembly is recommended to ensure reliable operation. Check the Unit OK and I/O Enabled LEDs for proper status indication. The block's noise suppression feature helps maintain signal integrity in electrically noisy environments. For storage, the unit can withstand temperatures from -40 to 100 degrees Celsius. No specific disassembly or contact cleaning procedures are required beyond periodic visual checks.

Compatibility & Integration

The IC660TBA021 is designed for use with GE Fanuc Genius I-O RTD input blocks, specifically the IC660BBA021. The block supports data transmission to the PLC CPU in degrees Fahrenheit, degrees Celsius, or counts, offering flexibility in system integration.
