Ever since our establishment, our company has been catering to the variegated requirements of different domestic and global markets by providing a wide range of Yudian Make Artificial Intelligent Controllers. These are designed by our experts incorporating latest technology. To meet the variegated requirements of our customers, we offer a wide range of controllers ranging from simple temperature controllers to powerful process controllers.
Provide various models from simple temperature controllers to powerful process controllers, and ensure to meet users different requirements.
Platformization design: different models have compatible wiring and front panel.
Universal programmable input. Can freely select multiple inputs of thermocouples, RTDs, and linear currents/voltages/resistors. Users can define input specification and non-linear graduation table or manufacture download special input specifications.
Incorporated with multiple control modes of ON-OFF control, standard PID, AI PID and AI MPT. Advanced AI control algorithm with auto-tuning and self-learning functions achieves excellent control without overshoot or undershoot, and is suitable for precise measurement and control of temperature, pressure, flow, level, humidity, .......
Modularized structure, supports outputs of SSR voltage, linear current/voltage, relay switch, TRIAC no contact switch, thyristor single/three phase zero crossing trigger, and thyristor single-phase phase-shift trigger.
Valve positioning supports valve position feedback and can save or replace servo amplifier.
Auto/manual control with auto/manual bumpless switch and manual auto-tuning, suitable for valve control.
Heating/refrigerating dual output control.
Programmable alarms. Provides multiple alarms of high limit, low limit, deviation high limit and deviation low limit, with the function of alarm blocking at the beginning of power up. Every alarm can be freely allocate to any alarm output (AL1, AL2, AU1 or AU2).
Retransmission function can retransmit PV (process value) or SV (set value) into standard current single. With high precision current output module X3 or X5, the retransmission accuracy is 0.2% FS with temperature shift less than 100ppm.
External set value function can set SV by external analog signal, and can compose complicate control system such as cascade or ratio.
Advanced AIBUS+ communication protocol, supports RS485 and RS232C communication interface with maximum 800 communication addresses. Cooperated with high speed communication technology, a middle or big computer control system with thousands of points can be built.
Program instruments can provide 10 or 50 segments programming control, change temperature in any slope, and have programmable and operable commands such as jump (loop), run, pause, and stop, and can change the program at any time. Smooth control can be achieved by applying AI Control algorithm which has curve approaching function.
Event outputs can be added to the program, and cooperate with external equipments.
External switch signal input, can switch SV1/SV2 or control run, pause or stop of a program.
Various dimensions are selectable, light bar panel and rail mounted no panel instruments are also available.
Note: Different models have different functions. For detail, see the comparison table below.
