GE Fanuc IC693TCM302

Part Number: IC693TCM302

The IC693TCM302 is a high-performance Temperature Control Module designed for the Series 90™-30 Programmable Logic Controller (PLC). This versatile module features eight channels of thermocouple input and eight channels of control output, enabling efficient temperature monitoring and control. The module operates in both locked and open-loop modes, making it suitable for various applications. It offers a resolution of 12 bits or 0.2°C and can manage common mode voltage of ±12V. Key fault detection capabilities include open thermocouple and reverse connection monitoring, as well as the identification of out-of-tolerance temperatures.

The temperature control function is facilitated across eight independent zones, each maintaining a precision of ±1°C relative to the specified setpoint. With dual operational modes—auto and manual—the module can execute closed-loop PID (Proportional-Integral-Derivative) control in auto mode, while manual mode allows for open-loop operation. Each zone's Pulse Width Modulation (PWM) output is programmable, with a range from 0.1 to 60 seconds, and the output duty cycle adjusts according to PID coefficients from 0 to 100% with a 0.1% resolution.

IC693TCM302 includes a power-on self-test (POST) feature that assesses memory and peripheral circuitry, accompanied by continuous monitoring of external power status via a front panel interface. The module is equipped with 12 LED indicators that provide real-time feedback on thermocouple status, as well as alerts for open-circuit and reverse polarity faults. In the event of a thermocouple fault, the control zone can either maintain its manual duty cycle output or immediately deactivate.

This module integrates seamlessly with the Series 90-30 PLC, allowing users to combine logic and control functionalities effectively. Configuration and reference data transfer utilize (%Q and %AQ) data blocks, enhancing interoperability. Furthermore, the TCM contains a replaceable 2 Amp user fuse located on the circuit board behind the front bezel and is compatible with the Series 90-30 expansion baseplate. Utilizing Logic Master 90 software, users can ensure that local application programming does not interfere with module operation.

Technical Specifications include a module type classified as a Thermocouple Input, an output voltage range of 18 to 30 volts DC, and a load current rating of 100 mA per point. The IC693TCM302 consumes 150 mA at 5 VDC and supports both internal and external DC power sources.
