Functional Features Screw terminals facilitate power and communication cable wiring and maintenance disassembly. Built-in surge suppression components absorb instantaneous surge voltage from long external signal cables. Internal signal traces transmit power and synchronization signals upward to the upper controller module. Reserved test terminals support on-site loop signal measurement without removing wiring. Precise mechanical positioning ensures reliable electrical contact between terminal base and controller plug-in module.
Application Scenarios DeltaV DCS main control cabinets in chemical plants, oil refineries, thermal power plants and pulp and paper mills. It cooperates with DeltaV main controller modules to connect redundant communication cables and external power wiring for control unit.
Performance Parameters Internal signal traces keep low signal attenuation for power and synchronization signal transmission. Surge protection components absorb instantaneous high voltage pulse effectively. Screw terminals maintain stable electrical connection under cabinet long-term vibration. Metal contact pins keep consistent signal transmission after repeated controller module plugging.
Material Composition Main body uses flame-retardant PA engineering plastic. Nickel-plated copper alloy screw terminals. Multi-layer glass fiber epoxy PCB internal substrate. Solid-state surge suppression components. Metal positioning pins with anti-oxidation plating.
Structural Features Fixed installation base mounted on DIN rail inside control cabinet. Front side with multiple screw wiring terminals for power and communication cables. Top contact pins connect with controller module bottom connector. Reserved test terminals for loop signal inspection. Positioning buckle ensures accurate alignment with plug-in controller module.
Working Principle External power and redundant communication cables connect to screw terminals of terminal base. Power and synchronization signals pass through built-in surge protection circuit and internal PCB traces. Signals transmit upward through contact pins to controller module plugged above. Surge suppression components absorb transient overvoltage from external cables to protect controller circuit. Test terminals lead out signal loop for field measurement and fault inspection.
Installation Requirements Mount terminal base on standard DIN rail inside control cabinet and lock fixed buckle. Route shielded twisted-pair field cables and fasten each terminal screw. Implement single-point grounding for cable shield wire inside cabinet. Confirm top contact pins fully contact with controller module bottom connector after module insertion. Separate controller communication wiring from high voltage power wiring.
Precautions for Use Cut off external power before wiring modification. Check terminal screw tightness during regular cabinet inspection. Do not apply overvoltage to signal and power terminals. Keep contact pins clean without dust and metal debris. Do not modify internal circuit of terminal base.
