三、Basic Functions of Temperature Instruments

1. GWL (Economical temperature controller with 0.2-level accuracy, featuring GWL artificial intelligence regulation technology, multiple alarm modes, transmission, and communication functions).
2. GWLP (Adds 30-segment time program control function on the basis of GWL).

• Specifications of modules installed for the instrument's multi-functional input/output (MIO) (supports installation of K3, V, U, I2, I4, etc.).

1. Specifications of modules installed for the instrument's main output (OUTP) (supports installation of L2, L4, W1, W2, G, K1, K3, X3, X5, etc.).
2. Specifications of modules installed for instrument communication (COMM) (supports installation of S, S4, V, U, etc.).
3. Specifications of the instrument's expanded 分度 table (omitted if not applicable). All GWL series instruments have stored common thermocouples, thermal resistors, and various linear voltage (current) and resistance input modes. However, if input signals beyond the above specifications are used, users are allowed to expand one input specification.
4. Instrument power supply: 100~240VAC.
5. Dual-channel relay normally open contact switch output module (capacity: 30VDC/2A, 250VAC/2A, universal type).
6. Photoelectrically isolated RS485 communication interface module; S4: Photoelectrically isolated RS485 communication interface module with built-in isolated power supply.
7. Analog 4~20mA/0~20mA input interface, including 24VDC/25mA power output for two-wire transmitters.

四、Human-Machine Touch Screen and Remote Interface

1. Product Overview

The AI-3270S/3270W/3270Y/3290S/3290W/3290Y multi-functional configurable true-color human-machine interface touch screen, with a low-power CPU as the core, inherits Yudian's classic low-power and high-reliability design concept. It embeds a powerful, flexible, and efficient Yudian HMI configuration software, supporting not only connection to Yudian's rich AI series instruments but also mainstream brand intelligent instruments, PLCs, inverters, etc. It can be widely used in various industrial, scientific research, and civil fields.

2. Functional Features

1. 800×480 resolution wide-screen display with clear and delicate images, providing operators with a comfortable visual experience.
2. Adopts a long-life LED backlight, resulting in low energy consumption, long service life of the touch screen, high screen brightness, uniform color, and stronger expressiveness.
3. Multiple communication modes, equipped with 2 serial ports (RS232 and RS485) and 2 USB ports; AI-3270W/3290W is also configured with a 10/100M adaptive Ethernet interface.
4. Through the USB interface, recorded data can be easily stored in a USB flash drive; a mouse can be used to operate the touch screen, and even a barcode scanner and other devices can be connected for input.
5. After AI-3270W/3290W is connected to the network via the Ethernet port, multiple computers in the same local area network can connect simultaneously via a browser to realize display and operation on the computer side.
6. Equipped with an HMI configuration application. The configuration development environment is a visual and "foolproof" integrated development environment, making configuration convenient. The system comes with a rich object library and graphics, supports custom graphics, and allows importing images in formats such as BMP, JPG, and GIF, enabling free creation of various industrial interfaces. It also has rich animation connection methods (e.g., flickering, filling, moving) to make the interface vivid and intuitive.
7. Powerful data processing function, capable of saving and viewing various data, and generating reports and various trend graphs.
8. Multi-level security configuration, ensuring the operational safety of the configuration project through the cooperation of user management and security zones.
9. Equipped with P2P cloud function (no public IP required, enabling intranet penetration monitoring), allowing remote monitoring and operation via mobile devices such as smartphones and tablets.
