Material Composition
Robust industrial-grade housing with high-precision amplifiers and precision resistor networks. Conformal-coated PCBs for environmental protection.
Structural Characteristics
Standard 8-channel FBM module with front-panel channel status LEDs. Precision backplane connector supports hot-swapping.
Working Principle
External 0-20mA signals enter the module, are converted to voltage across precision resistors, amplified, and digitized by the A/D converter before being transmitted over the fieldbus.
Installation Requirements
Signal wires must use shielded twisted pairs with shields grounded at the cabinet side only. Observe correct polarity for current loop connections.
Precautions for Use
Never apply voltage signals to this module. Ensure transmitter type matches software configuration when replacing sensors.
