Technical Specifications Operating Supply Voltage: 24 VDC ±10% Power Consumption: ≤ 2 W Number of Input Channels: 2 independent synchronous sampling channels Supported Signal Types: 4‑20 mA DC, 0‑10 V DC, Pt100 RTD A/D Resolution: 16‑bit Sampling Rate: 10 samples per second for dual‑channel synchronous update Measurement Accuracy: ±0.1 % of Full Scale Range Galvanic Isolation Voltage: 2500 V AC between field channel and control bus Operating Temperature: ‑25 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mounting Form: Standard 35 mm DIN‑rail mounting Protection Class: IP20 Certifications: CE
Functional Features Realizes synchronous sampling of two independent analog input channels. Supports multi‑signal types including current, voltage and Pt100 temperature sensor. High‑strength galvanic isolation eliminates ground‑loop interference between field side and control system. Built‑in open‑circuit and short‑circuit fault detection for sensor loops. Front‑panel LED indicators display power‑on, running and channel fault status. Compact DIN‑rail structure saves cabinet installation space. Detachable terminal blocks facilitate field wiring and module replacement.
Application Scenarios Small‑size automation cabinet analog signal acquisition. On‑site local control unit temperature and pressure monitoring. Machinery equipment auxiliary process parameter measurement. Compact PLC system analog input spare‑part replacement.
Performance Parameters MTBF: 232000 hours Shock Resistance: 10 g, 11 ms Vibration Resistance: 5 g, 10 Hz‑500 Hz Fault tolerance: Single‑channel fault does not affect normal operation of another channel.
Installation Requirements Mount module onto standard 35 mm DIN‑rail inside control cabinet. Carry out cabinet protective earth connection according to system grounding specification. Field sensor wiring uses shielded twisted‑pair cables. Separate power wiring and signal wiring routing. Confirm sensor signal type matches channel configuration setting before power‑on. Ambient environment keeps within defined temperature and humidity range without condensed moisture. Tighten terminal screws with specified torque value to avoid poor contact.
