Functional Features Screw terminals facilitate field analog safety control cable wiring and maintenance disassembly. Built-in surge suppression components absorb instantaneous surge voltage from long field instrument cables. Internal signal traces transmit analog safety control signals to the upper SIS analog output module. Reserved test terminals support on-site loop signal measurement without removing wiring. Precise mechanical positioning ensures reliable electrical contact between terminal base and SIS analog output module.
Application Scenarios DeltaV SIS safety control cabinets in chemical plants, oil refineries, thermal power plants and pulp and paper mills. It cooperates with DeltaV SIS analog output modules to send 4-20mA safety control signals to field control valves and safety regulating instruments.
Performance Parameters Internal signal traces keep low signal attenuation for analog safety control 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 SIS 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 safety control cabinet. Front side with multiple screw wiring terminals for field safety control instrument cables. Top contact pins connect with SIS analog output module bottom connector. Reserved test terminals for loop signal inspection. Positioning buckle ensures accurate alignment with plug-in SIS module.
Working Principle Field analog control instrument cables connect to screw terminals of terminal base. Safety analog control signals pass through built-in surge protection circuit and internal PCB traces. Signals transmit upward through contact pins to SIS analog output module plugged above. Surge suppression components absorb transient overvoltage from field cables to protect SIS module circuit. Test terminals lead out signal loop for field measurement and fault inspection.
Installation Requirements Mount terminal base on standard DIN rail inside safety 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 safety cabinet. Confirm top contact pins fully contact with SIS analog output module bottom connector after module insertion. Separate analog safety control 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.
