Technical Specifications Supply Voltage: 24 VDC Power Consumption: Less than 15 W Total Channel Quantity: 32 analog input channels Input Signal Types: 0‑20 mA, 4‑20 mA, DC voltage signals Conversion Accuracy: 0.1% full scale Operating Temperature Range: ‑20 ℃ to +60 ℃ Storage Temperature Range: ‑40 ℃ to +85 ℃ Relative Humidity: 5 %‑95 %, non‑condensing Protection Grade: IP20 for module body Dimension: 120 mm × 90 mm × 45 mm Weight: 0.4 kg
Functional Features Supports high‑speed analog‑digital conversion for multi‑point process variables. Built‑in hardware filtering suppresses electromagnetic interference from field equipment. On‑board self‑diagnostic circuit detects channel open‑circuit, short‑circuit and power supply abnormal status and reports fault codes to host controller. Hot‑swap capability allows module replacement while cabinet power remains on. Supports configuration download and parameter calibration through system engineering software.
Application Scenarios Power plant DCS control systems, petrochemical process control, metallurgy production monitoring, water treatment automation, pulp and paper industry. It collects temperature, pressure, flow and liquid level analog signals from field transmitters.
Installation Requirements Install onto standard DCS cabinet back‑plane slot. Ensure 24 VDC power supply meets ±10% tolerance requirement. Keep 20 mm minimum clearance between adjacent modules for heat dissipation. Ground cabinet protective ground terminal strictly. Confirm backplane bus connector fully inserted and locked. Avoid installing beside high‑power frequency‑conversion devices.
Usage Notes Cut off field signal wiring before module disassembly even with hot‑swap function. Do not apply over‑range voltage or current to input channels. Conduct regular calibration for analog channels according to plant maintenance cycle. Prevent conductive dust and moisture from entering module housing. Verify firmware version compatibility before replacement. Complete fault log backup when module fault alarm appears.
