It can simultaneously display real-time measurement signals from four independent channels, and can be equipped with 8-channel or 4-channel independent alarm output, RS485/232 communication and other optional functions, making it the optimal solution for industrial systems requiring synchronous multi-point measurement and inspection.
Key Benefits
High-Precision Measurement & Universal Signal Compatibility
This multi-circuit industrial measurement controller delivers a high measurement accuracy of 0.2%FS±1 word, ensuring reliable data acquisition for critical industrial processes. It supports full-range input signals including current, voltage, resistance and thermocouple, with input impedance ≤250Ω for current signals and ≥500KΩ for voltage signals, maximum input current up to 30mA, and maximum input voltage ≤6V. The -1999 to 9999 display range supports 0-3 adjustable decimal point settings, adapting to diverse industrial measurement requirements.
Configurable Control & Seamless System Integration
The HDM5740 digital display controller provides configurable 8-channel or 4-channel independent relay alarm outputs, with contact capacity of AC220V/2A, DC24V/2A. It supports upper and lower limit alarm modes with adjustable return difference, avoiding frequent relay action at critical points. Adopting standard MODBUS communication protocol, this industrial digital controller with RS485 communication offers stable transmission, with RS485 communication distance up to 1km and RS232 up to 15m, supporting baud rates from 1200bps to 9600bps, seamlessly integrating with industrial control systems and SCADA platforms.
Rugged Industrial-Grade Design & Easy Installation
With a standard snap-in structure, the controller is available in 160×80mm (horizontal), 80×160mm (vertical) and 96×96mm (square) dimensions, adapting to various panel installation needs. It operates reliably in ambient temperatures of 0-50°C and relative humidity ≤85% RH, with a wide power supply range of AC 100-240V (50-60HZ) or DC 20-29V, and power consumption ≤4W, ensuring long-term stable operation in harsh industrial sites.
