Siemens | Simatic S5 6ES5457-8EA12

Product Details

• Part Number 1 6ES5457-8EA12

Product Description

For Simatic S5 system applications, Siemens 6ES5457-8EA12 provides the function of a Digital Input Module.

For replacement planning, a digital input module receives discrete on/off states from field contacts and devices, then makes those states available to the controller for monitoring, sequencing, alarms, and interlocks. The assigned system function should be preserved through installation and service.

In a SIMATIC S5 system, module selection is governed by the controller family, rack arrangement, electrical interface, and configured program. The exact article number should be matched before installation. Selection should account for the intended surrounding hardware configuration.

When this product is used for lifecycle support, technicians should confirm the installed revision, connection arrangement, and system assignment rather than assuming interchangeability with a similarly named module. Existing connection and module records should guide replacement work.
