Functional Features Screw terminals provide reliable clamping force for field instrument wires. Built-in surge protection components absorb transient voltage spikes from field cables and protect I/O module channels. Reserved test points allow technicians to measure loop signals without disconnecting instrument cables. Internal signal traces realize one-to-one mapping between field terminals and I/O module channels. Quick lock buckle realizes fast connection and separation between terminal base and I/O card.
Application Scenarios DeltaV distributed remote I/O cabinets used in oil & gas, chemical and pharmaceutical industries. It serves as wiring interface for analog input, analog output and digital I/O field instruments.
Performance Parameters
- Terminal clamping structure maintains stable electrical contact under long-term cabinet vibration
- Surge suppression circuit responds rapidly to absorb transient overvoltage pulses
- Internal signal traces keep low signal attenuation for 4-20mA analog signals and 24VDC digital signals
- Screw terminals maintain stable performance after repeated wiring and disassembly 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 are gold-plated copper alloy.
Structural Features Front assembly structure matched with DeltaV I/O modules. Multiple rows of screw wiring terminals arranged orderly. Independent test jacks beside each signal channel. Mechanical locking buckle connects tightly with I/O module. Rear contact pins mate with front connector of I/O card.
Working Principle Field instrument cables connect to screw terminals of the terminal base. Signals pass through built-in surge protection components and internal PCB traces, then transmit to contact pins connected with I/O module. When lightning or switching surge generates overvoltage on field cables, protection components divert surge energy to protective ground. Test points directly access signal loop for field measurement and troubleshooting.
Installation Requirements Align terminal base connector with front connector of I/O module and fasten mechanical buckle. Strip wire insulation to specified length and tighten terminal screws with standard torque. Route shielded field cables and implement single-point grounding inside control cabinet. Avoid pulling force applied to terminals from cable routing.
Precautions for Use Disconnect field instrument power before wiring. Do not over-tighten terminal screws to prevent thread damage. Inspect tightness of terminal screws periodically. Prevent metal debris from falling into terminal assembly. Do not apply voltage exceeding rated value to terminals.
