Display Size: 12.1 inch, 1280 × 800 high-resolution panel
Brightness: 600 cd/m² for clear outdoor visibility
Communication: 5 × CAN (supporting CANopen / SAE J1939 / User-defined)
I/O Resources: 20 inputs and outputs for flexible signal control
Programming Environment: CoDeSys 3.5
The SPD-121-H1x is a rugged 12.1-inch industrial display designed for mobile and off-highway machinery that operate in harsh environments such as construction, agriculture, mining, and sanitation. It combines high-brightness visibility, rich I/O resources, and multiple communication channels to deliver reliable control and monitoring performance.
The display features a 12.1-inch TFT-LCD panel with a 1280 × 800 resolution, offering sharp and vivid images even under direct sunlight. With a brightness level of 600 cd/m², operators can easily read parameters and monitor data outdoors. The screen supports fast boot, allowing the system to power up in just a few seconds — ideal for applications where every second counts.
To ensure seamless data exchange, the SPD-121-H1x provides 5 independent CAN communication channels, all electrically isolated for signal reliability.
It supports multiple industry-standard protocols, including:
CANopen
SAE J1939
User-defined CAN protocols
This flexibility makes the unit suitable for a wide range of control architectures, from distributed I/O networks to centralized control systems.
The display integrates 20 I/O channels that can be freely configured for inputs or outputs, supporting both digital and analog signals:
8 × DI (H/L)
12 × DI (H)
14 × AI (U 0–10 V)
2 × AI (U 0.4–32 V)
8 × AI (R 4–20 mA)
4 × PI (≤ 30 kHz)
1 × PI (AB)
8 × DO (H)
8 × PWM (H)
This rich I/O capability allows direct connection to sensors, actuators, and controllers without additional modules.
Internally, the SPD-121-H1x is equipped with:
DDR4 8 Gbit memory
Flash 64 Gbit storage
FRAM 256 Kbit for non-volatile data retention
These configurations ensure smooth operation, stable program storage, and reliable data logging in real-time control applications.
To support diverse system integration needs, the device offers:
1 × USB port for data updates or configuration
1 × RS232 port for serial communication
1 × Ethernet port for network connection
4 × AHD video inputs (720P / 1080P) for real-time camera monitoring
The front panel integrates 10 independent keys and one navigation keypad, enabling intuitive menu navigation and parameter adjustment even when wearing gloves.
The display supports CoDeSys 3.5 programming, allowing users to develop customized logic, visualizations, and control functions efficiently.
