Product Overview

The IC693TCM302B acts as a dedicated high-performance processor for precise thermal regulation within the GE Fanuc Series 90-30 PLC system. This module offloads complex PID (Proportional-Integral-Derivative) calculations from the main CPU, providing autonomous control for up to two independent temperature loops. It directly interfaces with various thermocouples and RTDs to monitor and maintain setpoints in heating and cooling applications. We supply this unit in 100% Brand New factory condition to ensure the highest measurement accuracy and control stability for your process loops.

Technical Specifications

Engineering Advantages

• Distributed Processing Power: By executing PID algorithms locally on the module, the IC693TCM302B prevents the PLC CPU scan time from impacting temperature control precision. This ensures a consistent, high-speed update rate for sensitive thermal processes.

• Auto-Tuning Capabilities: The module features an integrated auto-tuning function. This allows engineers to automatically calculate optimal PID constants for a specific thermal mass, drastically reducing the time required for system commissioning and startup.

• Direct Sensor Interface: The hardware eliminates the need for external temperature transmitters. You wire thermocouples or RTDs directly to the module, reducing potential points of failure and minimizing electrical noise interference associated with long signal conversion chains.

• Flexible Output Logic: The module manages various output types, including time-proportioning (for solid-state relays) or analog outputs (via the PLC backplane), adapting to different heater and valve control strategies.

FAQs

Does this module support both Thermocouples and RTDs simultaneously?

Yes, the IC693TCM302B is highly flexible. You can configure each of the two channels independently to accept either a thermocouple or an RTD, depending on your specific sensor requirements.

How does this "B" revision differ from the original "A" version?

The "B" revision indicates an updated hardware platform with improved firmware stability and component longevity. It remains fully backward compatible with all Series 90-30 racks that previously used the IC693TCM302A.

Is there a need for external calibration?

The module performs continuous self-calibration and internal cold-junction compensation. However, we recommend verifying the loop accuracy during annual maintenance to account for sensor drift in the field.

Is this product a new or surplus unit?

We guarantee this IC693TCM302B is 100% Brand New. It ships in the original GE Fanuc factory packaging with all security seals intact to ensure authentic performance.
