Technical Specifications

Engineering Advantages

The GE Fanuc IC693TCM302 excels in accuracy by maintaining a low thermocouple impedance of 30 Ohms, ensuring signal integrity across all 8 input channels. Despite its specialized measurement capabilities, the module maintains a lightweight profile at approximately 0.4 kg, making it easy to install in any standard Series 90-30 rack slot. Built-in safety features include a 700 mA typical overload protection and minimal off-state leakage, which protect both the module and connected field devices from electrical transients. For storage in non-operational periods, the unit is rated to withstand temperatures from -40 to 85°C.

Technical FAQs

Q1: Does this module require an external power supply?
A1: Yes. While it draws 150mA from the PLC backplane at 5V DC, the control outputs and internal circuitry require an external 18 to 36V DC power source capable of handling a 2.5A inrush current.

Q2: Can I use different types of thermocouples on the same module?
A2: The IC693TCM302 is designed for consistent thermocouple monitoring; however, check your software configuration (Logicmaster or Proficy) to ensure the specific thermocouple types (J, K, T, etc.) are correctly mapped to each channel.

Q3: How does the overload current protection work for the outputs?
A3: The outputs are designed with a typical 700mA threshold. If a short circuit or high-current event occurs, the module will sustain this load for a minimum of 2ms before triggering protective measures to prevent board failure.
