Functional Features Screw terminals provide reliable clamping for field instrument wires. Built-in surge suppression components absorb transient voltage surges from field cables and protect I/O module channels. Reserved test points allow technicians to measure signal values without disconnecting field wiring. Internal signal routing realizes one-to-one signal mapping between field terminals and I/O card channels. Mechanical locking mechanism ensures tight connection between terminal base and I/O module.
Application Scenarios DeltaV control cabinets in chemical, power and oil & gas industries. It serves as field wiring interface for analog input, analog output, digital input and digital output I/O modules.
Performance Parameters
- Terminal clamping force maintains stable contact under long-term cabinet vibration
- Surge components respond rapidly to absorb transient overvoltage pulses
- Signal routing traces keep low signal loss for 4-20mA and 24VDC signals
- Screw terminals maintain stable electrical connection after multiple wiring operations
Material Composition Housing made of flame-retardant PA engineering plastic. Internal signal traces on flame-retardant glass fiber epoxy PCB. Nickel-plated copper screw terminals. Integrated transient suppression diodes and resistors. Connection contact pieces adopt gold-plated copper alloy.
Structural Features Front-mounted assembly for DeltaV I/O modules. Multiple screw wiring terminals arranged in rows. Integrated test jacks beside each signal channel. Mechanical locking buckle fastens the terminal base with I/O card. Rear contact pins mate with the front connector of I/O module.
Working Principle Field instrument cables are connected to screw terminals of the terminal base. Signal flows through internal PCB traces and protection components, then transmits to mating contacts connecting to I/O module. Transient voltage suppression components shunt surge energy to ground when overvoltage appears on field wiring. Test points directly access signal loop for field measurement and troubleshooting.
Installation Requirements Align the terminal base connector with the front connector of I/O module and fasten mechanical buckle. Strip wire insulation to specified length and tighten terminal screws with standard torque. Route field shielded cables with single-point grounding at cabinet side. Keep wiring tidy and avoid cable tension on terminals.
Precautions for Use Disconnect field instrument power before wiring operation. Do not over-tighten terminal screws to avoid thread damage. Inspect terminal screw tightness periodically. Prevent metal debris falling into terminal assembly. Do not apply voltage exceeding rated value to terminals.
