Secure Screw-Clamp Termination for Field Wiring
The Siemens 6ES7392-1AN00-0AA0 features 40 screw-clamp terminals for reliable wire connections. Rising cage design ensures vibration-resistant termination in factory environments. Each terminal accepts solid or stranded wires from 0.5 mm² to 2.5 mm². Users can terminate wires quickly with standard screwdrivers.
Two-Row Design for High-Density Connections
The terminal block organizes 40 positions into two rows of 20 terminals each. This two-row design optimizes cabinet space and simplifies wiring routing. The numbered positions enable clear identification of each connection point. Users can wire the block efficiently without confusion or errors.
Compatible with All S7-300 I/O Modules
This terminal block fits all SIMATIC S7-300 digital and analog I/O modules. Users can use the same connector type across multiple module families. The plug-in design allows quick module replacement without rewiring. This compatibility reduces spare parts inventory and simplifies maintenance.
Durable Construction for Long Service Life
Brass terminals with tin plating provide excellent conductivity and corrosion resistance. Polycarbonate insulation meets UL 94 V-0 flammability requirements for safety. The connector housing withstands vibration, shock, and temperature extremes. Users can rely on the terminal block for years of trouble-free service.
Clear Identification and Color Coding
Gray housing with numbered positions enables clear identification of each terminal. Users can apply custom labels for signal names and wire numbers. This identification simplifies troubleshooting and maintenance procedures. The terminal block’s design reduces the risk of wiring errors during installation.
Easy Installation Without Special Tools
Users can install the terminal block without special tools or training. The plug-in interface ensures proper pin alignment with the module’s contacts. Screw-clamp terminals accept wires quickly with standard screwdrivers. Users can wire the block either before or after mounting on the module.
