IC660BBA026 GE Fanuc enius I/O RTD Input Block

Product Overview

The IC660BBA026 (IC660BBA026) is a high-precision, 6-channel Resistance Temperature Detector (RTD) input block within the GE Fanuc Genius I/O family. This intelligent distributed I/O module interfaces directly with standard RTD sensors to provide accurate temperature data acquisition over the Genius bus. Engineered for thermal monitoring in plastic extrusion, chemical reactors, and large motor bearings, the IC660BBA026 converts low-level resistance signals into digital temperature values. By processing signals at the source, this block eliminates the need for expensive long-run compensated wiring back to a central controller. We supply this component as 100% Brand New, ensuring factory-calibrated accuracy and long-term reliability for your process control system.

Technical Specifications

The IC660BBA026 features advanced signal conditioning and supports multiple RTD types with high resolution.

Engineering Advantages

• Universal Sensor Support: This block accommodates a variety of Platinum, Nickel, and Copper RTDs. Engineers configure the sensor type and temperature scale (Celsius or Fahrenheit) via software, providing a flexible solution for diverse global installations.

• Enhanced Lead Compensation: The IC660BBA026 supports 3-wire RTD configurations, allowing the module to automatically compensate for lead wire resistance. This ensures measurement accuracy even when the block is mounted at a significant distance from the actual sensing point.

• Proactive Fault Detection: The module monitors each channel for "Open Sensor," "Short Circuit," and "High/Low Alarm" limits. It transmits these diagnostics over the Genius network, allowing operators to identify failed probes before they trigger a process shutdown.

• Distributed Architecture: By utilizing the Genius bus, the IC660BBA026 operates as a standalone intelligence unit. It continues to monitor and provide local diagnostics even if communication with the main CPU is momentarily interrupted, maintaining a safe "Hold Last State" or "Go to Zero" output profile.

FAQs

• Can I mix different types of RTDs on the same block?

  No. The block typically applies the selected configuration to all six channels. All sensors connected to a single IC660BBA026 must be of the same type (e.g., all Pt 100).

• Does this block require external calibration?

  The IC660BBA026 comes factory-calibrated. However, it features self-calibration routines that run periodically to compensate for component aging and ambient temperature drifts, maintaining high accuracy over time.

• How does the block handle sensor burnout?

  The block detects an open circuit (burnout) and immediately reports a diagnostic fault to the controller. You can program the system to fail-safe by defining how the CPU should interpret the resulting out-of-range data.

• Is the terminal base included?

  The IC660BBA026 consists of the electronic module and the terminal block. Our 100% Brand New units ship as complete assemblies ready for DIN-rail or panel mounting.
