Technical Specifications
Number of input channels: 16. Input signal types: 4-20mA, ±10V DC, thermocouple, RTD configurable per channel. Resolution: 16-bit. Accuracy: ±0.1% full scale @ 25°C. Isolation: 500V AC channel-to-bus, 250V AC channel-to-channel. Backplane current draw: 350mA @ 5V DC. Power dissipation: 1.75W maximum. Operating temperature range: 0°C to +60°C.
Functional Features
Per-channel configurable input ranges support diverse field instrument compatibility. Built-in signal conditioning and digital filtering suppress electrical noise. Open-circuit detection and over-range/under-range alarm functions per channel. Hot-swap capability enables module replacement without system shutdown. Per-channel status indicators provide real-time operating status.
Application Scenarios
It is widely applied in thermal power plant DCS systems, petrochemical process control, water treatment monitoring, gas turbine control systems, and continuous manufacturing process data acquisition.
Material Composition
Front panel: flame-retardant PC/ABS plastic. Circuit board: FR-4 glass epoxy substrate with copper traces. Connectors: gold-plated copper alloy for reliable backplane contact. Internal components: industrial-grade precision integrated circuits.
Structural Characteristics
It adopts standard Symphony Plus module form factor with front panel status LEDs, labeled channel identifiers, rear backplane connector, and modular card guide design for rack mounting.
Working Principle
It receives analog voltage or current signals from field transmitters and sensors, performs signal amplification, filtering and A/D conversion through internal conditioning circuits, converts analog values into digital data, and transmits the processed measurement data to the Symphony Plus controller via the system backplane for process control and monitoring.
Installation Requirements
Install in any available I/O slot of a Symphony Plus chassis. Ensure the module is fully seated in the card guide and backplane connector. Use shielded twisted pair cables for field analog signals, grounded at the system side only. Verify channel configuration matches field instrument output ranges. Ensure reliable chassis grounding.
