Functional Features Screw terminals support connection of 2-wire, 3-wire and 4-wire RTD sensor cables. Built-in overvoltage protection components protect RTD module from field surge interference. Reserved test ports allow technicians to measure sensor resistance without cable disconnection. Internal PCB traces transmit resistance signals to RTD module accurately. Mechanical locking buckle achieves stable assembly between terminal base and RTD input module.
Application Scenarios Ovation DCS cabinets of thermal power plants, chemical plants and pharmaceutical factories. It connects platinum RTD temperature probes used for boiler, pipeline and reactor temperature measurement.
Performance Parameters Terminal clamping structure maintains stable low-resistance contact under cabinet vibration. Protection components absorb transient overvoltage pulses. Internal signal traces maintain low additional resistance for precise RTD measurement. Terminals keep stable performance after repeated wiring.
Material Composition Housing uses flame-retardant PA engineering plastic. Internal circuit board adopts flame-retardant glass fiber epoxy PCB. Nickel-plated copper screw terminals. Integrated surge protection components. Contact pins connecting to RTD module use gold-plated copper alloy.
Structural Features Front assembly matched with Ovation RTD input module. Multiple groups of screw terminals for multi-wire RTD sensors. Independent test jack for each temperature channel. Mechanical locking buckle connects tightly with RTD module. Rear contact pins mate with front connector of RTD card.
Working Principle Field platinum RTD temperature sensors connect to screw terminals of terminal base. Resistance signals change with temperature variation and transmit through internal PCB traces and protection components to RTD input module. The RTD module converts resistance value into temperature reading. Protection components divert surge energy to ground when abnormal overvoltage appears on sensor cables. Test jacks allow direct resistance measurement of temperature probes.
Installation Requirements Align terminal base connector with front connector of RTD input module and fasten locking buckle. Select corresponding terminal group according to RTD wire type, strip wire insulation and tighten terminal screws with standard torque. Use shielded twisted pair cables for RTD sensors, apply single-point shield grounding inside cabinet. Keep RTD cables away from high-power cables.
Precautions for Use Cut off sensor loop power before wiring. Do not over-tighten terminal screws. Check wire connection mode matches sensor wire definition. Inspect terminal tightness periodically. Prevent metal debris falling into terminal assembly.
