Functional Features Screw terminals provide reliable clamping for transmitter signal wires. Built-in surge suppression components absorb transient voltage spikes generated by lightning or power switching. Reserved test jacks allow technicians to measure loop current without disconnecting instrument cables. Internal signal traces realize one-to-one signal mapping between field terminals and AI module channels. Mechanical locking buckle achieves stable assembly between terminal base and analog input module.
Application Scenarios Ovation DCS cabinets for thermal power plants, chemical plants and industrial water treatment projects. It supports wiring of pressure transmitters, temperature transmitters, flow transmitters and liquid level transmitters.
Performance Parameters Terminal clamping force maintains stable contact performance under long-term cabinet vibration. Surge suppression circuit rapidly absorbs transient overvoltage pulses. Internal traces keep ultra-low signal attenuation for 4-20mA analog signals. Terminals maintain stable electrical performance after repeated wiring operations.
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 transient voltage suppression diodes and resistors. Contact pins use gold-plated copper alloy.
Structural Features Front assembly matched with Ovation analog input module. Multiple rows of screw wiring terminals arranged in order. Independent test jack beside each analog channel. Mechanical locking buckle connects tightly with analog input module. Rear contact pins mate with front connector of AI card.
Working Principle Field 4-20mA transmitters connect to screw terminals of terminal base. Analog current signals pass through surge protection components and internal PCB traces, then transmit to contact pins connected with analog input module. When overvoltage appears on field cables, surge protection components divert surge energy to protective ground. Test jacks directly access signal loop for on-site current measurement and loop debugging.
Installation Requirements Align terminal base connector with front connector of analog input module and fasten locking buckle. Strip wire insulation to specified length and tighten terminal screws with standard torque. Use shielded twisted pair cables for transmitter wiring and apply single-point grounding inside cabinet. Avoid applying pulling force to terminals from cable routing.
Precautions for Use Cut off field transmitter power before wiring. Do not over-tighten terminal screws. Inspect screw tightness periodically. Prevent metal debris from falling into terminal assembly. Do not apply voltage exceeding rated value to terminals.
