Product Role & System Fit
In industrial automation, temperature control is both a control and safety issue. The IC693TCM303A is a dedicated Temperature Control Module (TCM) engineered for the GE Fanuc Series 90-30 programmable logic controller family. Unlike generic I/O cards that merely read analog values, this specialty module integrates multiple thermocouple inputs with discrete control outputs and autonomous control logic — enabling precise thermal regulation without placing heavy burden on the main PLC CPU.
The Series 90-30 platform has been a workhorse in sectors as varied as plastics extrusion, heat treatment furnaces, food processing ovens, and chemical reactors. In all of these applications, temperatures must not only be monitored but adjusted within tight bands to ensure product quality and equipment safety. The IC693TCM303A fits into this environment as an “intelligent” control element: it reads eight thermocouple sensors, compares setpoints against measured values, and issues eight discrete control outputs to heaters, actuators, valves, or solid-state relays accordingly. This offloads closed-loop control tasks from the CPU, which can then focus on broader logic functions like sequencing, safety interlocks, and communication.
Physically, the module occupies a standard Series 90-30 I/O slot and communicates with the rest of the system over the PLC backplane. Unlike CPU modules or communication cards, the TCM is rated specifically for temperature control tasks and integrates field-ready connectors for thermocouple wiring and external power, simplifying cabinet layout and improving maintainability.
In a typical system architecture, a Series 90-30 CPU (for example, an IC693CPU360 or similar) handles logic and high-level sequencing, while the IC693TCM303A handles real-time temperature feedback and control. Integration in configuration tools (such as LogicMaster 90 or Proficy Machine Edition) lets engineers define setpoints, control parameters, and alarm thresholds as part of the overall ladder logic or control strategy, maintaining coherence between thermal regulation and overall process automation.
