Functional Features Screw terminals support convenient wiring of external communication cables and power cables. Built-in surge suppression components absorb transient high voltage pulse induced on long external cables. Internal signal traces transmit communication and status signals between external cables and upper interface module. Precise positioning structure ensures stable electrical contact between terminal base and KJ2231X1 plug-in module. Modular structure supports individual replacement without removing other rack modules.

Application Scenarios DeltaV DCS main control cabinets and remote I/O cabinets in chemical plants, oil refineries and natural gas processing facilities. It cooperates with KJ2231X1 series interface modules to complete external wiring termination for rack communication and status monitoring.

Performance Parameters Internal signal traces keep low attenuation for communication and status signal transmission. Surge protection components suppress transient overvoltage effectively. Screw terminals maintain stable electrical contact under long-term cabinet vibration. Contact pins keep reliable connection after repeated module plugging.

Material Composition Main body substrate adopts flame-retardant PA engineering plastic. Nickel-plated copper alloy screw terminals. Multi-layer glass fiber epoxy PCB. Solid-state surge suppression components. Anti-oxidation plated metal positioning contact pins.

Structural Features DIN rail fixed terminal base assembly. Front side with multiple screw wiring terminals for external communication and power cables. Top contact pins connect to bottom connector of KJ2231X1 series interface module. Positioning buckle guarantees accurate alignment with plug-in module. Integrated cable guide groove organizes external wiring neatly.

Working Principle External communication and power cables connect to screw terminals of terminal assembly. Signals pass through built-in surge protection circuit and internal PCB traces. Signals transmit upward through contact pins to KJ2231X1 series interface module installed on top. Surge components absorb transient high voltage pulse from external cables to protect interface module circuit.

Installation Requirements Mount terminal assembly on standard DIN rail inside control cabinet and lock fixed buckle. Connect external cables and tighten each terminal screw. Adopt single-point grounding for cable shield wire inside cabinet. Confirm top contact pins fully contact with interface module after module installation. Separate communication wiring from high-voltage power cables.

Precautions for Use Cut off external cable power before wiring modification. Inspect terminal screw tightness regularly. Do not apply overvoltage to signal and power terminals. Keep contact pins free from dust and metal debris. Do not modify internal circuit of terminal assembly.
