Yudian Temperature Controller AI-808 Series

Characteristics of Xiamen Yudian Temperature Controller AI-808 Series

Suitable for measurement, alarm and transmission of temperature, pressure, flow rate, liquid level, etc
Supports various thermocouples, thermistors, linear voltage, current, resistance, and radiation (infrared) thermometers, and has special input specifications for expanding input sockets. It can also customize non-linear correction tables for special inputs, with measurement accuracy of 0.2 or 0.1 levels (V7.5 version).

The second input, in addition to the main input, is used for external reference or valve signal feedback functions, and can form complex control systems such as cascade or ratio regulators.

Modular output supports SSR voltage, linear current (voltage), relay contact switch, thyristor contactless switch, single-phase and three-phase thyristor zero crossing trigger, single-phase thyristor phase-shift trigger output, i.e. position proportional output (directly driving valve motor forward/reverse), etc., with a control cycle of 0.24~60 seconds

● It has multiple adjustment methods such as standard PID, AI artificial intelligence regulation APID or MPT, and has self-tuning and self-learning functions. It has excellent control characteristics without overshoot or overshoot, and can also use positional control (ON-OFF) function.

AIBUS communication protocol: Supports RS485 or RS232C communication interfaces, and with fast communication technology, can easily build large and medium-sized computer control systems with a scale of thousands of points.

Xiamen Yudian AI-808 supports multiple alarm functions such as upper limit, lower limit, deviation upper limit, and deviation lower limit, and can freely define 4 alarm output ports, supporting multiple alarm signals to be output from the same position. Equipped with functions such as power on exemption from alarms, to avoid misoperation of power on alarms.

It can convert the measured value (PV) or the given value (SV) into a standard current signal output, providing 14 bit high-resolution, 0.2 level output accuracy, and current output performance better than 100ppm/℃ temperature drift.

The permission to view and modify parameters can be defined, and users are allowed to customize passwords and customize instruments that best suit their operating habits.
