Description

Siemens 6ES7492-1AL00-0AA0 Front Connector is a standard 40-pin spring-type front connector designed for the SIMATIC S7-400 series programmable logic controller (PLC) system. It serves as a key component to establish fast, reliable, pluggable electrical connections between S7-400 signal modules, function modules, communication processors, and field devices, supporting the construction of high-availability, easy-to-maintain industrial control systems. Equipped with spring clamp wiring technology, it allows wire insertion and removal by pressing the release lever, eliminating the need for crimp terminals or screwdrivers, and supports wire cross-sections ranging from 0.25 to 2.5 square millimeters (AWG24–12). Key technical specifications include a rated voltage of 250V AC/DC, rated current of 10A, firmware version V2.2.0, and 24 input / 16 output I/O points. It features a modular mounting and structural design, with a program capacity of 32 kbyte, product type marker CPUST30DC/DC/DC, package dimensions of 23mm×100mm×120mm, and a weight of approximately 0.4kg. It is suitable for most digital, analog, and some high-power signal circuits.
