GFX4 and GFXtermo4 provide four-loop control: independent PID or on/off action for control of heat-only, cool-only or heat/cool processes. Self-tuning and autotuning features accommodate different operating conditions, and the controls have soft-start function for preheating requirements. Inputs include four universal process inputs (thermocouple, RTD, milliamp, volt and millivolt); four optional auxiliary inputs (thermocouple or millivolt) with programmable functions; and two digital inputs with programmable functions. Outputs include four integrated solid-state relay outputs, with total power rated at 30, 60 or 80 kW at 480 V, configurable for single- or three-phase operation.
