3. Usage Instructions
Installation: Standard cabinet slot mounting; keep horizontal installation inside the control cabinet.
Wiring: Use shielded twisted-pair cables for analog signal lines; separate analog lines and power lines strictly.
Debugging: Set signal type (mA/V) via DCS software before power-on; calibrate zero point and range.
Operation: Observe module status indicators; monitor analog data stability through upper computer system.
Maintenance: Regularly clean surface dust; check terminal tightness and signal line aging every six months.
4. Important Precautions
Do not install in humid, condensed water and corrosive gas environments.
Keep away from high-power electromagnetic interference equipment to avoid signal fluctuation.
Cut off all power supply before wiring, disassembly and maintenance.
Do not apply signal exceeding the rated voltage or current range to prevent channel burnout.
Avoid severe vibration and mechanical impact during transportation and installation.
Ensure smooth cabinet ventilation to prevent temperature drift of analog acquisition accuracy.
Unauthorized disassembly of internal components is strictly prohibited.
