TP04G-AS2 is a waterproof industrial terminal panel designed for human-machine interface applications in manufacturing and automation environments. It features a 128×64 point STN-LCD monochromatic display with 72 mm (W) × 40 mm (H) viewing area, capable of displaying up to 8×4 Chinese characters maximum, and supports multilingual text including ASCII, Traditional Chinese (BIG 5), and Simplified Chinese (GB2324-80) fonts. The unit operates on 24V DC input power at 3.5W maximum consumption and includes dual communication ports: RS-232 (COM1) and RS-485/RS-422 (COM2), both supporting transmission speeds from 9600 bps to 115200 bps. Built-in features include 256 KB flash memory for program storage, 32 KB system RAM, a real-time clock (RTC) with CR2030 lithium battery backup (1200-hour battery life), and status indication LEDs for alarm, RS-232, and RS-485/RS-422 communication. The panel achieves IP65/NEMA4/UL Type 4 waterproof rating for indoor use, operates reliably across 0–50°C ambient temperature with 20–90% relative humidity (non-condensing), and withstands vibration up to 1.0G (10–150 Hz) and shock up to 15G (11 ms). This terminal panel is ideal for industrial control systems, process monitoring, and data acquisition applications where robust, waterproof human-machine interfaces are required in demanding operational environments.
