I.Product Positioning and Core Functions
1.Target Application Scenarios
Industrial Automation Control Cabinets:
Used for power and signal connections for PLC input/output modules,sensors,and actuators.Supporting 24V DC or 220V AC voltage levels,it meets the electrical interface requirements of the IEC 61131-3 standard.
Power Distribution Systems:
In low-voltage distribution boxes and switchgear,it serves as a terminal block for main or control circuits.It carries currents ranging from a few amperes to tens of amperes and is suitable for applications such as lighting,motor starting,and inverter control.
Process Control and Instrumentation Systems:
Connects field instruments such as temperature transmitters,pressure transmitters,and flow meters.Its vibration-resistant design ensures long-term stable operation and reduces measurement errors caused by poor contact.2.Core Features
Spring-Cage Connection Technology:
Utilizing Weidmüller’s patented spring-cage connection,pre-loaded springs clamp the conductors.Tightening the screws requires no tools,enabling one-handed operation and a connection time of less than 5 seconds per terminal.
High-Reliability Contact:
The springs are made of a highly elastic copper alloy(CuSn6)with a tin(Sn)or silver(Ag)surface plating,ensuring low contact resistance(<0.5mΩ)and corrosion resistance,making them suitable for harsh environments such as humidity and salt spray.
Multi-Wire Compatibility:
Supports direct connection of solid-strand wires(0.2-4mm²),stranded wires(0.2-2.5mm²),and wires with ferrules,without the need for additional processing,accommodating various installation practices and wire types.
Modular Design:
Terminals can be freely combined,allowing for parallel connection of multiple terminals using bridges to meet high current or equipotential bonding requirements.Marking strips can also be installed for easy line identification and maintenance.II.Technical Specifications and Performance Parameters
