Description
YL-370A Level and Flow Process Control Trainer System object
1. On-site control cabinet: including control power supply, incoming line voltmeter, work indicator light and integrated control cabinet integrated with terminal connectors, with protective measures such as leakage and grounding protection; the front door panel of the control cabinet is embedded with imported plexiglass panels, which can be used as the cabinet When the door is closed, the working status of the components in the cabinet can be observed in real time.
2. Controlled object: The controlled object of this system is a second-order water tank, and the second-order water tank is used to simulate the control object in the industry. Water storage tank specification 400×400×400mm, control water tank specification 200×200×300mm.
3. Controller: Use SIMATIC WinAC RTX for PC-based control, which has extremely high performance and can provide strict real-time performance. Its high performance is embodied in the high-speed control application calculation which only occupies fewer resources of the microprocessor. In addition to processing control tasks, the CPU has sufficient resources to meet a large number of other complex PC tasks that require parallel processing.
4. Artificial intelligence regulator: supports various thermocouples, thermal resistances, linear voltage, current, resistance and radiation (infrared) thermometers, etc., and has expansion input sockets to install special input specifications, and can customize the nonlinear correction of special inputs Table, can connect Cu50 copper resistance as thermocouple cold junction compensation, 0.1~0.2 level measurement accuracy, temperature drift less than 30PPm/℃.
High-precision measurement and temperature control minimize energy waste.
Modular output supports SSR voltage, linear current (voltage), relay contact switch, thyristor non-contact switch, single-phase, three-phase thyristor zero-crossing trigger, single-phase thyristor phase shift trigger output that is position ratio Output etc.
With standard PID, AI artificial intelligence adjustment APID or MPT and other adjustment methods, with self-tuning, self-learning functions, excellent control characteristics without overshoot and no undershoot, it can also use the position control (ON-OFF) function; Dual independent parameter PID can support heating/cooling dual output function.
Support RS485 or RS232C communication interface.
It supports multiple alarm functions such as upper limit, lower limit, upper limit of deviation, and lower limit of deviation, and 4 alarm output ports can be freely defined, and multiple alarm signals can be output from the same location. Equipped with functions such as exemption of alarms after power-on, to avoid malfunctions of power-on alarms.
You can define the permissions for parameter viewing and modification, and allow users to customize their passwords, and tailor the instrument that best suits their own operating habits.
It has the functions of manual/automatic non-disturbance switching and manual self-tuning.
