Technical Specifications Matched with 9902 series I/O modules, screw type wiring terminals. Operating temperature: -40℃ ~ +70℃, built-in signal surge suppression components.
Functional Features Field signal wiring terminal distribution, signal transmission between field side and I/O module, surge suppression, convenient module hot swap maintenance.
Application Scenarios All types of 9902 control cabinet wiring, analog, digital and pulse signal terminal connection.
Performance Parameters Stable signal transmission, reliable screw connection, good anti-surge capability.
Structural Characteristics PCB terminal base with dense screw terminals, matched backplane connector for I/O module insertion.
Working Principle Field cables connect to screw terminals on this base. Signals pass through the base circuit to the mating connector and are sent to the inserted I/O module.
Installation Requirements Mount on cabinet DIN rail or rack, tighten all terminal screws after wiring.
Usage Notes Label each terminal clearly, disconnect field power before replacing the I/O module.
