Material & Structural Characteristics

1. Housing Material: High-strength flame-retardant ABS plastic, UL94-V0 fire resistance grade, anti-aging, anti-electromagnetic interference
2. Internal Circuit Board: Double-sided copper-clad industrial PCB with tin plating on all signal traces; surface-mount industrial-grade IC chips
3. Mounting Structure: Standard 35mm DIN rail snap-on mounting structure, quick disassembly without tools
4. Terminal Structure: Spring-type push-in wiring terminals, no screwdriver required for wiring, anti-loose, suitable for multi-core shielded signal cables

Working Principle

1. Digital Input Path: External 24V sensor switching signal is filtered by RC hardware filter, then converted to digital logic level by optocoupler isolation circuit, and transmitted to the internal main control MCU for data caching
2. Analog Output Path: The main control MCU receives digital setpoint values sent by the upper PLC via bus, converts digital signals to smooth analog voltage/current through high-precision DAC chip and low-noise operational amplifier circuit, and outputs to external analog actuators
3. Bus Communication Logic: The built-in industrial Ethernet transceiver chip realizes real-time data exchange between the module and the master PLC; the MCU performs channel data packaging, fault status reporting, and parameter storage

Installation Requirements

1. Mounting Condition: Install only inside sealed electrical control cabinets with dust-proof and moisture-proof functions; strictly prohibit outdoor open-air installation
2. DIN Rail Installation: Use standard 35mm top-hat DIN rail; ensure the rail is horizontally fixed, module snap fully engaged with the rail without shaking
3. Wiring Specification:
   • Power cable: 0.75–1.5mm² shielded DC cable, separate power wiring from signal wiring to avoid interference
   • Signal cable: 0.5–1.0mm² double-shielded twisted pair cable; separate digital signal lines and analog signal lines into different wiring ducts
4. Cabinet Environmental Control: Cabinet internal operating temperature must be maintained between -20°C and +70°C; install cooling fans or heaters for extreme temperature workshop environments
5. Grounding Requirement: Connect the module’s PE grounding terminal to the cabinet’s equipotential grounding bus with a 1.5mm² ground wire to eliminate electromagnetic interference

Operation & Maintenance Notes

1. Do not connect AC power to the DC 24V power terminal; reverse power connection will trigger internal protection and stop module operation
2. Analog output channels cannot be short-circuited for a long time; continuous short-circuit will cause internal power amplifier overheating and permanent damage
3. Regularly inspect push-in wiring terminals every 3 months to check for loose wires caused by equipment vibration
4. All bus communication parameter configurations must match the upper PLC master station; mismatched baud rate or IP address will result in complete loss of signal transmission
5. Do not disassemble the module housing without professional maintenance personnel; disassembly will damage internal isolation circuits and void product warranty
6. Avoid installing the module next to high-power inverters, servo drives, contactors and other strong electromagnetic interference components; maintain a minimum 15cm spacing
