Functional Features Screw terminals simplify wiring of field load cables and support convenient disassembly during equipment maintenance. Built-in surge suppression components absorb back electromotive force pulse from field inductive loads. Internal PCB traces transmit digital switching signals downward from digital output module to field wiring terminals. Precise positioning structure ensures stable electrical contact between terminal base and digital output plug-in module. Modular structure allows independent replacement of terminal base without removing the upper I/O module.
Application Scenarios DeltaV DCS control cabinets deployed in chemical plants, oil & gas facilities, pharmaceutical factories and thermal power plants. It works with DeltaV digital output modules to drive field solenoid valves, auxiliary relays and motor contactors in interlock and sequence control systems.
Performance Parameters Internal signal traces maintain low attenuation for discrete switching signal transmission. Surge protection components suppress transient voltage spike from inductive loads effectively. Screw terminals keep stable electrical connection under long-term cabinet vibration. Contact pins maintain reliable connection after repeated plugging of digital output module.
Material Composition Main body substrate adopts flame-retardant PA engineering plastic. Nickel-plated copper alloy screw terminals. Multi-layer glass fiber epoxy PCB substrate. Solid-state surge suppression components. Anti-oxidation plated metal positioning contact pins.
Structural Features DIN rail fixed base structure. Front side equipped with multiple screw terminals for field load wiring. Top metal contact pins mate with DeltaV digital output module bottom connector. Positioning buckle locks terminal base and aligns with plug-in module. Integrated wiring channel guides field cables neatly inside control cabinet.
Working Principle Control switching signals from digital output module transmit downward through top metal contact pins to internal PCB traces of terminal base. Signals pass through surge suppression circuit and reach screw wiring terminals for field load cables. When field inductive loads cut off, surge suppression components absorb back electromotive force pulse to protect I/O module circuit. Screw terminals transmit discrete on-off signals to field solenoid valves, relays and contactors through external cables.
Installation Requirements Mount terminal base on standard DIN rail inside control cabinet and fasten mounting buckle. Connect field load cables and tighten each terminal screw. Adopt single-point grounding for cable shield wire inside cabinet. Check full contact between top pins and digital output module after module insertion. Keep output load wiring separated from weak analog signal wiring.
Precautions for Use Cut off field load power before wiring adjustment. Inspect terminal tightness regularly. Do not apply overvoltage to signal terminals. Keep contact pins clean without metal scraps and dust. Do not alter internal circuit of terminal base.
