Functional Features Screw terminals simplify wiring work of field transmitter shielded cables. Surge suppression components absorb instantaneous high voltage pulse induced on long field cables. Internal PCB traces transmit analog signal to upper analog input module. Reserved test terminals support on-site loop current testing without removing cable wiring. Precise positioning structure ensures stable electrical contact between terminal base and analog input module.
Application Scenarios DeltaV DCS control cabinets in chemical plants, oil refining plants, pharmaceutical factories and pulp mills. It cooperates with DeltaV analog input modules to collect measurement signals from pressure, flow, liquid level and temperature transmitters.
Performance Parameters Internal signal traces maintain low signal attenuation during 4-20mA analog transmission. Surge protection components suppress transient overvoltage effectively. Screw terminals keep stable connection under long-term cabinet vibration. Contact pins maintain reliable electrical contact after repeated module plugging.
Material Composition Flame-retardant PA plastic main housing. Nickel-plated copper alloy screw terminals. Multi-layer flame-retardant glass fiber epoxy PCB substrate. Solid-state surge suppression components. Metal contact pins with anti-oxidation plating.
Structural Features DIN rail fixed base structure. Front side equipped with multiple screw terminals for field instrument wiring. Top metal contact pins mate with DeltaV analog input module bottom connector. Independent test terminals for loop signal measurement. Positioning buckle locks terminal base and aligns with plug-in module.
Working Principle Field analog transmitter cables connect to screw terminals of terminal base. 4-20mA analog current signal passes through surge protection circuit and internal PCB traces. Signal transmits upward through metal contact pins to analog input module installed on top. Surge components absorb transient high voltage pulse from field cables to protect I/O module circuit. Test terminals lead out signal loop for field measurement and fault inspection.
Installation Requirements Install terminal base on standard DIN rail inside control cabinet and fasten mounting buckle. Route shielded twisted-pair cables and tighten each terminal screw. Set single-point grounding for cable shield wire inside cabinet. Check full contact between top pins and analog input module after module insertion. Keep analog wiring separated from high-voltage power cables.
Precautions for Use Cut off field transmitter power before wiring adjustment. Inspect terminal tightness regularly. Do not apply overvoltage to signal terminals. Keep contact pins clean without dust and metal scraps. Do not alter internal circuit of terminal base.
