Core functions

16-channel independent differential acquisition， hardware RC first-order filtering (-3dB@1Hz) to suppress on-site interference； Built-in polynomial engineering quantity conversion， can directly configure temperature and pressure compensation linear algorithm； Full-channel open circuit， short circuit， over-range hardware self-diagnosis， fault codes uploaded to the control system； Single-channel fault does not affect other circuits' acquisition； Modules support hot-swappable power-on of the rack， replacement spare parts automatically download configuration parameters. Applicable scenarios

Temperature / pressure / level transmitters for petrochemical plants, monitoring of auxiliary parameters for thermal power boilers, collection of parameters for continuous production processes in coal chemical industry, DCS analog quantity collection for pharmaceuticals / water treatment.

Installation and Maintenance Instructions

Field instruments use shielded twisted-pair cables, with the shielding layer grounded at a single point in the cabinet; for 4-20mA circuits, strictly select the matching FTA base with a precise 250Ω resistor; conduct annual inspection of channel accuracy; for damp cabinets, take measures to prevent terminal moisture;严禁 unplugging or plugging connectors and connecting lines between the card and the base while the equipment is powered on.
