Description

C7GA322FF0000 4-Loop High-Speed Digital Temperature Controller

The C7GA322FF0000 Digital Temperature Controller is a high-performance 4-loop temperature controller designed for advanced industrial temperature control applications. With high-speed sampling, precision accuracy, and powerful connectivity options, it enables reliable and efficient control of multiple heating processes from a single device.

Equipped with four universal inputs for thermocouples, RTDs, or analogue signals, the controller provides flexible integration into a wide range of systems. Its Ethernet (Modbus/TCP) and RS-485 (Modbus/RTU) communication allows seamless PLC integration and remote monitoring, while the built-in display eliminates the need for separate touch panel interfaces.

The C7G series also supports pattern control functions, PID auto-tuning, and predictive maintenance features, including heater resistance monitoring using current and voltage inputs. With microSD data storage capability and high-speed 10ms sampling, it is ideal for complex industrial processes requiring precise multi-loop temperature management.
