Temperature Controllers Exceeding Your Expectations... High Speed and High Accuracy Multi-Drop Master Function Universal Input PXF series is a winner of the Good Design Award 2017 organized by the Japan Institute of Design Promotion.

Superior Versatility and Flexibility for a Wide Range of Applications Control output indicator Alarm output (DO) indicator →P7 Manual operation indicator Process value (PV) PID auto tuning indicator →P4 Parameter number MV Bar graph Digit selector Multi-Functional to Suit Your Needs In addition to 9 types of temperature control functions including on-off control, heating/cooling control, and 2-degrees-of-freedom PID, useful functions such as multi-drop control using RS-485 network and simple Fast Control (depends on input type and range) Operating Days Alarm watt-hour monitoring are...

Universal Input RS-485 Communication (option) SV can be transmitted to multi-PXFs through communication. Synchronous temperature-rise control is available in combination with 2-degrees-of-freedom PID. Synchronized heating function RS485 Example: injection molding machine Flow rate Multi-zone control (synchronized heating) Easy switchover by parameter setting Tallest PV Characters in the Industry Compact Design Bright and clear white PV display for optimal viewing With only 58-mm depth, compact enough to be installed on small equipment Size Selection Parameter Setting Available on PC 3...

Advanced Control Functions Parameter setting is available using the front keys or a PC with Fuji Electric’s loader software. Standard Functions On/off Control Control characteristic of ON/OFF action Simple and Basic Control When process value (PV) is below the set value (SV), PXF turns on the output to energize the heater, and vice versa. In this way, PXF keeps the temperature constant by turning the output on and off based on the SV as a threshold. PID Control with Auto Tuning Molding Machine Typical Control Based on PID Theory * Overshoot may occur due to external disturbance. Start/stop...

Open-Loop Supported PID2 Control Reduces overshoot in the processes where the controlled equipment is power cycled. Process value 7 Simple Program Control (Ramp Soak Function) 6 Self Tuning Control Auto-Tuned PID for Changing Temperature At power up, SV change, or during external disturbance, tuning is made automatically so that the PID parameters are re-optimized. *For some objects of control, PID values cannot be optimized. PXF automatically changes SV to the preset values at preset times. You can set up to 64 steps and 15 types of operation patterns. For example, when you bake four kinds...

Variety of Functions Expanding the Uses of Temperature Controllers and Improve the User Experience Standard Functions Easy Switching Among 8 Presets This enables optimum PID setting for changing process, materials, or PV. You can perform SV selection only, PID selection only, or PID selection according to PV. SV Soft Start Saves Energy at Startup Prevents the output being maximum when turning on the equipment (including the temperature controller). This is useful for suppressing the load at equipment startup. Control output (MV) MV without soft start Soft start output set value MV with soft...
