The Siemens 6ES7392-1BN00-0AA0 is a terminal block using a spring-loaded connection system, designed for 64-channel I/O modules of the S7-300 family. It serves as the wiring interface for connecting field I/O signals to the module, with a rated operating range of 0 °C to 60 °C.
Mechanical fit is defined by the dimensions: 120 mm wide, 46 mm tall, 48 mm deep. The spring-loaded terminals accept solid or ferruled stranded wire without requiring screwdriver torque — strip length and wire gauge follow standard S7-300 practice. Two units per packing unit; order multiples accordingly.
