Detailed Technical Parameters
The module features a compact standard industrial modular structure with overall dimensions of 110mm × 130mm × 60mm and a net weight of approximately 0.34kg. The lightweight and high-density design effectively saves control cabinet installation space, supporting centralized and modular layout of industrial safety instrument systems.
The module adopts a rated operating power supply of 24V DC industrial power supply with stable voltage tolerance for industrial power fluctuation. The typical operating current consumption is low, meeting the low-power operation requirements of long-term continuous system operation. Equipped with built-in overvoltage, overcurrent and short-circuit protection circuits, it effectively avoids module damage caused by on-site power supply abnormalities and wiring faults.
It is configured with 16 independent analog input channels, supporting standard 4–20mA current signal input for industrial field transmitters. Each channel supports switchable two-wire transmitter power supply function, realizing integrated signal acquisition and power supply output. The module-level isolation structure provides 1500V AC withstand voltage capability between internal system circuit and field signal side, effectively isolating interference and improving system safety.
Integrated standard HART communication protocol enables remote parameter configuration, transmitter diagnostic query and real-time data interaction for field smart instruments. The single-channel sampling rate reaches 10 samples per second, ensuring high-speed and high-precision acquisition and response of field analog signals.
The operating temperature range covers -20℃ to +70℃, fully compliant with ISA G3 industrial environmental standards. It operates stably under 5%–95% non-condensing industrial humidity conditions. The industrial-grade reinforced circuit and anti-corrosion structural design adapt to harsh industrial environments with dust, humidity and chemical corrosion.
