Siemens 6ES7392-1AM00-0AA0 SIMATIC S7-300 series

Siemens 6ES7392-1AM00-0AA0 is the front connector of Siemens SIMATIC S7-300 series PLC, which is used to connect the signal module (SM) to external sensors and actuators. The following is a detailed introduction:

I. Core functions and features

Spring type terminal

No tools are required, and wiring can be quickly done by pressing the spring clip. It supports 0.25-1.5mm² wires and greatly shortens the installation time.

Advantages: Vibration resistance is better than traditional screw terminals, suitable for frequent maintenance or vibration environments.

Applicable module types

Compatible with S7-300 series digital input/output modules (such as 6ES7 321-1BL00-0AA0) and some analog modules (need to confirm the specific model).

Electrical parameters

Rated voltage: DC 30V/AC 250V

Rated current: Maximum 2A per terminal

Protection level: IP20 (only for control cabinet)

Mechanical design

40-pin design: corresponding to 20 channels (each channel contains signal terminal and common terminal).

Anti-misinsertion function: match the module interface to avoid reverse installation.
