Functional Features High‑precision analog‑to‑digital conversion. Detect input signal over‑range situation. Option to supply loop power for field transmitters. Configurable digital signal filtering. Open‑circuit fault diagnosis for instrument loops. Supports HART signal pass‑through.
Application Scenarios Process‑variable signal collection for Ovation DCS deployed in thermal power plants, water‑treatment complexes and chemical‑processing factories.
Performance Parameters Measurement accuracy reaches ±0.1 % full‑scale value. Sampling cycle parameter configurable via system software.
Material Composition Flame‑retardant printed circuit board. High‑precision analog acquisition chips. Metal shielding cover reducing electromagnetic interference. Gold‑plated back‑plane connector contacts.
Structural Characteristics Plug‑in card matching Ovation cabinet back‑plane slots. Front‑panel terminal block for field instrument wiring. LED lamps display channel fault status.
Working Principle 4‑20 mA analog signal from field transmitter enters module terminal block. Signal passes filtering circuit then converted to digital value by ADC chip. Digital measurement data transmits to controller via back‑plane bus. Module hardware automatically judges open‑circuit and over‑range instrument‑loop conditions.
Installation Requirements Insert into Ovation standard cabinet slot. Field instrument wiring uses shielded twisted‑pair cable. Connect cable shield to cabinet grounding bar. Keep physical separation from inverter high‑frequency power cables.
Use Precautions Never connect voltage‑type signal to current‑input channels. Verify loop polarity before power‑on execution. Carry‑out module‑accuracy calibration periodically. Prevent conductive dust accumulation upon wiring terminals.
