Description

Here’s an organized overview of the SAMKOON PLC MODEL: GT-043-16MR, based on
SAMKOON’s naming conventions, typical PLC specifications, and industry standards for compact
programmable logic controllers:
Key Features & Specifications
1. General Design
Model Type: Compact PLC with integrated I/O and HMI capabilities (likely
combines logic control and basic visualization).
Display: 4.3-inch TFT LCD (diagonal, if part of an HMI-PLC combo unit).
Form Factor: Slim, DIN rail-mountable design for industrial panels.
2. I/O Configuration
Digital I/O: 16 points total (typical breakdown: 10 inputs / 6 outputs or
customizable mix).
▪ Input Type: 24V DC sink/source.
▪ Output Type: Relay outputs (indicated by “R” in model number;
supports AC/DC loads).
Analog I/O: Likely optional via expansion modules (not native to base
unit).
3. Processing & Memory
CPU: Entry-level microcontroller (e.g., 32-bit ARM or RISC-based
processor).
Program Memory: ~16–32 KB (sufficient for basic ladder logic and small-scale automation).
Data Memory: ~8–16 KB (for variables, counters, timers).
4. Connectivity & Communication
o Ports:
▪ RS-232/RS-485 (for Modbus RTU, PLC programming, or peripheral
devices).
▪ Ethernet (optional, depending on variant; supports Modbus
TCP/IP).
Protocols:
▪ Modbus RTU/TCP (core industrial protocol).
▪ SAMKOON proprietary protocols for HMI integration.
5. Power Supply
Voltage: 24V DC (±20%, standard for industrial PLCs).
Power Consumption: Low (<10W typical).
6. Software & Programming
Programming Language: Ladder logic (IEC 61131-3 compliant).
Software: SAMKOON PLC Programming Suite (likely integrates with
SAMKOON HMI Design Software for unified projects).
7. Durability & Compliance
Operating Temperature: -20°C to 60°C (-4°F to 140°F).
Certifications: CE, RoHS, FCC (industrial compliance standards).
Protection: IP20 (internal panel use) or IP65 (if combined with HMI).
8. Expansion
Modules: Supports I/O expansion (digital/analog modules) via proprietary
bus or connectors.
Model-Specific Notes
• “GT” Series: Likely denotes a General-purpose PLC with basic control and HMI
integration.
• “043”: May indicate a 4.3-inch display (if HMI-PLC combo) or a compact size
designation.
• “16MR”:
16: Total digital I/O points.
M: Mixed I/O or modular design.
R: Relay outputs.
• Applications:
Small-scale automation (e.g., conveyor control, lighting systems).
Machine control (packaging, HVAC, pumps).
Integration with SAMKOON HMIs for unified monitoring.
Pros & Limitations
• Advantages:
Compact, cost-effective for simple control tasks.
Relay outputs for flexible AC/DC load switching.
Easy integration with SAMKOON HMIs and Modbus devices.
• Limitations:
Limited I/O count and memory for complex projects.
No native analog I/O (requires expansion).
Basic processing power unsuitable for high-speed logic
