Material Composition
Industrial-grade flame-retardant housing with high-reliability amplifier circuits. Terminal blocks feature gold or tin-plated copper for reliable conductivity.
Structural Characteristics
Standard fieldbus module design with clear channel labeling and LED indicators. Secure backplane connector ensures tight mechanical and electrical coupling.
Working Principle
Constant current excites the RTD, voltage drop is measured to calculate resistance, then linearized per RTD tables and converted to temperature values for bus transmission.
Installation Requirements
Mount on a compatible FBM baseplate. Use shielded twisted pair with cabinet-side single-point grounding.
Precautions for Use
Never apply voltage or current signals. Verify RTD type and wire configuration match software settings.
