Product Description

RoHS CompliantLifecycle Status:

The SIMATIC S7-1500 digital input module is designed for use in automation systems, offering 64 digital input channels grouped in sets of 16. This module operates on a supply voltage of 24V DC and features a typical input delay of 3.2 ms. It adheres to input type 3 as per IEC 61131 standards, allowing for both sinking and sourcing configurations.

With dimensions of 35 mm in width, 129 mm in depth, and 147 mm in height, this module is compact and can be integrated into various control systems. The input current at signal 1 is rated at 2.7 A, and it can handle a permitted voltage at the input of -30 V. This module provides configurable digital inputs, enhancing its versatility in different applications.

It is important to note that cables and terminal blocks must be ordered separately as accessories. The module is not designed for redundancy, and it does not support any digital outputs.
