Technical Specifications 4-20mA analog input channels; Signal isolation; Supports HART signal; Redundant bus communication.
Functional Features HART protocol support for smart transmitters; Channel fault detection; Signal overrange alarm; Hot swap.
Application Scenarios Oil & gas, chemical, power plant process monitoring, pressure, temperature, flow transmitter signal collection.
Performance Parameters Input range: 4~20mA; Measurement accuracy: ±0.05%FS.
Structural Characteristics Rack pluggable module, front LED status indicators, matched terminal block for field instrument wiring.
Working Principle Receive 4-20mA or HART signals from field transmitters, isolate and convert analog signals into digital data, send to FCP controller via field bus.
Installation Requirements Install in DCS control rack; Use shielded cable for field instruments; Separate low-signal cable from power cable.
Usage Notes Verify HART configuration when connecting smart transmitters. Check channel calibration regularly. Cut relevant loop power before field wiring modification.
