Functional Features Screw terminals facilitate field switch cable wiring and maintenance disassembly. Built-in surge suppression components absorb instantaneous surge voltage from long field signal cables. Internal signal traces transmit discrete digital signals to the upper digital input module. Reserved test terminals support on-site loop signal measurement without removing wiring. Precise mechanical positioning ensures reliable electrical contact between terminal base and plug-in digital input module.
Application Scenarios DeltaV DCS control cabinets in chemical plants, oil refineries, thermal power plants and pulp and paper mills. It cooperates with DeltaV digital input modules to connect field limit switches, safety relays and hand-operated switches for discrete signal collection.
Performance Parameters Internal signal traces keep low signal attenuation for digital 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 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 field switch cables. Top contact pins connect with digital input module bottom connector. Reserved test terminals for loop signal inspection. Positioning buckle ensures accurate alignment with plug-in module.
Working Principle Field digital signal cables connect to screw terminals of terminal base. Discrete signal passes through built-in surge protection circuit and internal PCB traces. Signal transmits upward through contact pins to digital input module plugged above. Surge suppression components absorb transient overvoltage from field cables to protect digital input module 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 digital input module bottom connector after module insertion. Separate digital wiring from high voltage power wiring.
Precautions for Use Cut off field circuit power before wiring modification. Check terminal screw tightness during regular cabinet inspection. Do not apply overvoltage to signal terminals. Keep contact pins clean without dust and metal debris. Do not modify internal circuit of terminal base.
