Technical Specifications
Number of terminals: 32. Terminal type: screw clamp. Wire range: 22-12 AWG. Current rating: 10A per terminal. Voltage rating: 300V AC/DC. Screw torque: 0.5-0.7 N·m. Operating temperature range: -40°C to +85°C. Protection rating: IP20.
Functional Features
Screw clamp terminals provide reliable vibration-resistant connections. Clearly labeled terminal identifiers reduce wiring errors. Modular design mates directly with corresponding Ovation I/O modules. It supports daisy-chain power and common connections. Compact design saves cabinet space.
Application Scenarios
It serves as the field wiring interface for Ovation digital and analog I/O modules in DCS cabinets, process control panels, power plant control rooms and industrial automation systems.
Performance Parameters
Terminal current capacity: 10A per point. Voltage rating: 300V AC/DC. Contact resistance: <5mΩ. Operating temperature range: -40°C to +85°C. Vibration resistance: 5G @ 10Hz to 500Hz. Shock resistance: 30G.
Material Composition
Housing is UL 94 V-0 flame-retardant thermoplastic. Terminal clamps are copper alloy with nickel plating. Screws are steel with zinc plating.
Structural Characteristics
It features insulated terminal housing, parallel screw terminal rows, labeled channel identifiers, mounting footprints, and module mating interface for direct connection to I/O modules.
Working Principle
It acts as the physical and electrical interface between field wiring and I/O electronic modules. It routes power, common and signal connections from field cables to the plug-in I/O module via internal bus bars and contacts, and provides mechanical strain relief for field wiring.
Installation Requirements
Mount on standard DIN rail or panel mounting surface. Use 22-12 AWG solid or stranded copper wire. Tighten terminal screws to specified torque. Ensure reliable protective grounding connection. Mate I/O module firmly onto the terminal block until locked.
