Run signals between your control unit and external sensors and actuators using this digital I/O module from Siemens. It has 24 inputs and 4 outputs, so you can transmit data from multiple sources. The inputs are isolated to help reduce the risk of electrical interference that can spark up hazards. An integral safety function means the device can handle a fail-safe operation in your control system. A handy diagnostic alarm rings out to notify you of any potential faults, so you can jump on them immediately. You'll find this module used in plant engineering and oil and gas equipment. For a complete assembly, pair it with a PLC from the SIMATIC ET 200S range.

• Built-in front door to protect the socket
• Labelling field on the door for easy identification
• Reverse-polarity protection prevents damage caused by incorrect wiring
• Front-facing ports for ease of connection

A fail-safe function means the PLC monitors potential malfunctions in the machinery, quickly initiating a pre-saved safety solution if it detects a fault.

This module has LED indicators that show its operating status for at-a-glance monitoring.
