Technical Specifications Input Signal Type: 4‑20 mA DC, 0‑10 V DC Number of Channels: Multi independent analog input channels Conversion Resolution: 16‑bit Measurement Accuracy: ±0.12% full scale Channel‑to‑backplane isolation: 500 V RMS Operating Power Supply: 24 VDC Operating Temperature: 0 ℃ to +55 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Single‑slot plug‑in rack module Protection Grade: IP20 Certifications: CE
Functional Features Acquires multi‑channel industrial current and voltage analog signals. Built‑in hardware filter suppresses field electromagnetic interference noise. Completes high‑precision analog‑digital conversion and uploads data to main controller. Realizes channel‑level open‑circuit, short‑circuit and over‑range diagnosis. Provides front‑panel LED indication for power supply and channel fault alarm. Supports hot‑swap replacement complying with site safety procedures. Fully compatible with system rack backplane bus protocol.
Application Scenarios Chemical plant pressure, flow and liquid‑level signal collection. Water treatment plant process parameter monitoring cabinets. Power plant auxiliary system analog measuring‑point acquisition. Metallurgy factory process variable signal acquisition system.
Performance Parameters Channel sampling rate: 100 samples per second Temperature drift: Less than 0.04% full scale per 10℃ temperature change Fault tolerance: Single‑channel fault does not interrupt measurement of other normal channels Mean Time Between Failures: Exceeds 230000 hours Shock and vibration resistance: Complies with IEC 60068‑2‑6 industrial cabinet‑mount standard
Installation Requirements Install module into designated slot of standard system rack. Rack protective earth connection strictly follows system grounding specification. Field signal wiring must adopt shielded twisted‑pair cables. Separate power cable and signal cable routing to avoid crosstalk. Confirm input signal range matches module rated specification before power‑on. Module supports hot‑swap, replacement must comply with on‑site safety operation procedure. Ambient installation environment stays within defined temperature and humidity range without condensed moisture. Tighten terminal screws with manufacturer‑recommended torque value to prevent poor contact.
