Material Composition
Constructed with an industrial-grade flame-retardant shell and equipped with high-reliability amplification circuits. The terminal block uses premium conductive materials to ensure excellent conductivity and corrosion resistance.
Structural Characteristics
Standard fieldbus module design featuring clear channel identification and LED indicators. Precision backplane connectors ensure tight mechanical and electrical coupling.
Working Principle
The module samples the incoming 120 Vac signals, isolates them from the system ground, and converts the physical state into digital data frames. These frames are then transmitted to the main controller via the redundant fieldbus.
Installation Requirements
Installs directly onto a compatible FBM baseplate. Shielded twisted-pair cables must be used for field wiring, with the shield grounded at the cabinet side only to prevent electromagnetic interference.
Usage Precautions
Confirm that the signal type matches the software configuration before applying power. Never apply voltages exceeding the rated limits to the module terminals.
