Material Composition:

• Housing: Glass-fiber reinforced polycarbonate, grey (UL94 V-0)
• DC-DC Converters: Isolated, 3 kV rating, efficiency > 85%
• ADC: Texas Instruments ADS1115 or equivalent, 16-bit Sigma-Delta

Structural Features:

• DIN rail mountable
• 4 LED status indicators (one per output channel)
• Jumper-selectable input voltage (24 V / 110 V DC)
• Screw terminals with clear labeling

Working Principle:
Input power (24 V or 110 V DC) is converted to isolated 24 V DC outputs via high-frequency isolated DC-DC converters (1 MHz switching). Analog inputs are sampled by a 16-bit Sigma-Delta ADC and transmitted digitally over the backplane. Each output channel has overcurrent protection (550 mA trip point).

Key Advantages:

• Dual input voltage (24 V / 110 V DC) for flexible deployment
• Fully isolated outputs prevent ground loops
• 14-bit analog resolution for precision measurement
• Built-in overcurrent protection per channel

Applicable Industries:
Oil refineries, gas processing, remote monitoring stations, SCADA systems, environmental monitoring.

Installation Requirements:

• Mount on 35 mm DIN rail
• Set input voltage jumper before connecting power
• Use minimum 1.5 mm² wire for power connections
• Connect analog sensors with shielded cable

Usage Precautions:

• Set jumper to correct input voltage (24 V or 110 V DC) before power-up
• Do not exceed 500 mA per output channel
• Verify polarity before connecting field devices
• Do not operate in condensing humidity without IP65 enclosure
