Technical Specifications of HIMA HMIDT75X
Brand: HIMA; Model: HMIDT75X. This product is a high-reliability human-machine interface (HMI) terminal designed for industrial control systems, featuring advanced display and communication capabilities to support secure and efficient man-machine interaction in critical industrial environments. Display Specifications: Equipped with a 7.5-inch high-resolution LCD screen with a display resolution of 800 × 480 pixels, supporting 24-bit true color display for clear and vivid presentation of process data, system status, and operation menus. The screen adopts a resistive touch panel with excellent anti-interference performance, ensuring stable operation even in harsh industrial environments with vibration, dust, or oil contamination. 
Physical Characteristics: Dimensions (W × H × D) are 215 mm × 155 mm × 55 mm (excluding mounting brackets). The net weight of the device is approximately 1.2 kg, facilitating easy installation in standard control cabinets or panel-mounted locations. The housing is made of flame-retardant ABS material, complying with the UL 94 V-0 flammability standard, providing reliable protection against fire hazards. Environmental Conditions: Operating temperature range is -10°C to +55°C, allowing stable operation in extreme industrial temperature environments. Storage temperature range is -20°C to +70°C, ensuring product integrity during transportation and long-term storage. Relative humidity tolerance is 10% to 90% (non-condensing), and the device can withstand vibration of 5 Hz to 150 Hz with an acceleration of 1 g (IEC 60068-2-6) and shock of 15 g for 11 ms (IEC 60068-2-27), adapting to harsh industrial site conditions. Power Input: Supports a wide-range DC power input of 24 V DC ± 20% (19.2 V DC to 28.8 V DC), with a typical power consumption of 15 W and a maximum power consumption of 20 W. The input circuit is equipped with overvoltage, undervoltage, and reverse polarity protection functions to ensure the safety and stability of the power supply system.
Inputs/Outputs: Equipped with multiple communication interfaces for seamless integration with industrial control systems, including 1 × Ethernet port (RJ45, supporting TCP/IP, Modbus TCP protocols), 2 × RS485 serial ports (supporting Modbus RTU protocol, baud rate adjustable from 9600 bps to 115200 bps), and 1 × USB 2.0 host interface for data transfer and peripheral connection (e.g., USB flash drives for configuration backup and log export). Additionally, it provides 4 × digital input channels (dry contact, input voltage 24 V DC) for connecting external sensors or switches, and 4 × digital output channels (relay output, contact rating 2 A/250 V AC or 2 A/30 V DC) for controlling external devices such as alarms or indicators. Other Specifications: Compliance with international industrial standards including IEC 61508 (SIL 2) for functional safety, ensuring reliable operation in safety-critical applications. The device supports remote configuration and maintenance via Ethernet, enabling convenient system management without on-site operation. The operating system is a embedded Linux system with a user-friendly configuration software, allowing customized interface design and logic programming to meet diverse industrial application requirements.
