Description
  • Technical Specifications:
    • Output Channels: 16 channels​ (single-ended, sinking type)
    • Output Range: 4-20 mA​ (also supports 0-20 mA depending on CPU configuration)
    • Resolution: 12-bit​ (1/4096 counts)
    • External Load Impedance: 0-480 Ω​ @ 18 V, 220-740 Ω​ @ 24 V, 1550-1760 Ω​ @ 48 V
    • Max Supply Voltage: 48 V DC​ (within normal load impedance range)
    • Accuracy: ±0.2%​ @ 25°C, ±0.4%​ @ 0-60°C; Linearity error max ±0.025%
    • Power Requirement: 21.6-26.4 V DC​ external supply (100 mA base + 20 mA per active loop), 70 mA @ 5 V DC​ from backplane
    • Conversion Time: Max 400 µs​ full scale; 4.5 ms – 9 ms​ settling from data change
    • Operating Temperature: 0°C to +60°C​ (Storage: -20°C to +70°C)
    • Isolation: Output circuits isolated from PLC logic section
  • Functional Features: Removable terminal block for easy replacement without rewiring; all 16 channels refresh within one CPU scan cycle; no jumper setting required.
  • Performance Parameters: Interference rejection -70 dB; offset error max ±3 counts; full scale error ±8 counts.
  • Material Composition: Industrial grade plastic housing (UL 94V-0flame retardant); PCB with through-hole and SMT components.
  • Structural Characteristics: Modular plug-in design for DL405 base/extension rack; removable wiring header; status indicators per channel (if equipped) or module health LED.
  • Working Principle: Receives digital data from PLC backplane bus; DAC​ converts digital values to proportional current; constant current source drives output loop; isolation barrier decouples field side from logic side.
  • Advantages: High channel density (16 outputs in one slot); simplifies maintenance via removable terminals; fast refresh synchronized to CPU scan.
  • Applicable Industries: Manufacturing Automation, Food Processing, Material Handling, Water/Wastewater Treatment.
  • Model Series: Koyo DirectLOGIC DL405​ Series I/O Modules.
  • Installation Requirements: Install in DL405 CPU or expansion base unit; secure module latch; provide stable 24 V DC​ external power for current loops; ensure common ground reference appropriately.
  • Usage Precautions: Do not exceed 48 V​ max supply on output loops; match load impedance to supply voltage to prevent saturation; ensure external power polarity is correct; avoid shorting outputs without current limiting.
