Machine-level block I/O devices with IP65/67 protection

16 December 2019

Siemens has launched a new generation of machine-level block I/O devices.

The new IP65/67 rated Simatic ET 200eco PN I/O family includes five digital I/O devices as well as an IO-Link master device. 

In their new industrial metal enclosure, the devices are protected from UV radiation and harmful substances even under adverse environmental conditions, making it possible to use the devices outside. 

The devices are supplied with power via an L-coded plug, resulting in a higher current-carrying capacity. This enables longer cable routes in the field, and the supply and connection of more energy-intensive components (such as valve terminals) without the need for more supply cables.

The new I/O devices feature individually configurable M12 sockets and support S2 redundancy, making them suitable for use in redundant systems. Thanks to the internal Modular Shared Input (MSI) and Modular Shared Output (MSO), the user has simultaneous and independent read access to the current switching state of module inputs and outputs from multiple controllers, without the need for additional programming overhead. This is said to enhance machine and plant transparency.

The shared device function means that the I/O device channels can be split between two IO controllers to allow for the creation of flexible automation concepts.
