The benefits for you

Addition of safe I/O modules and further non-safe function modules to the portfolio, which are operated via the same coupler.

Easy to install and service thanks to simple and fast assembly by means of a safe sliding mechanism.

Space-saving, staircase-shaped wiring level with spring-loaded clamping technology.

With additional supply modules - up to 64 modules possible on the backplane bus.

The right tool for the perfect solution

In conjunction with the new MOVI‑C® CONTROLLER portfolio, interaction between the product portfolio of SEW‑EURODRIVE and external field units is optimized. Take advantage of the wide range of function modules and their combination options. Simply integrate them into the EtherCAT® bus of the controller via the bus coupler and use the full functionality in daily practice: For example, read in binary as well as analog signals or SSI encoder signals, or obtain data from counter or measuring modules, e.g. energy consumption.

Suitable I/O modules are also available for Safety over EtherCAT® for the special requirements in functionally safe areas.

Digital 16-way I/O modules round off the MOVI-PLC® portfolio

Digital modules with 16 input and output channels enable a compact and space-saving design of your system. The modules have an easy-to-install wiring level with spring-loaded terminal technology.

Properties and technical data

A module unit is made up of a terminal module and an electronics module. These are connected using a secure sliding and locking mechanism. The terminal module combines clamps, a fixture for the electronics module and the backplane bus connector. This means only the electronics module is replaced during servicing, by simply pulling it out of the terminal module. The wiring and mounting on the 35 mm DIN profile rail remain as they are. The electronics modules can be supplied with voltage and/or divided into separate potential groups by using additional supply modules.

The stepped arrangement of terminals on the terminal module using proven spring-clamp technology with highly reliable contacting enables fast, clear and safe wiring. The integrated status LEDs and the labeling strip on the front of the electronics modules ensure unique, channel-specific assignment and clear display of the channel status. The backplane bus concept with a speed of 48 Mbit/s also makes for very short response times.

In addition, a high system density can be achieved through digital input and output modules with up to 16 channels.

Areas of application of the I/O modules

Our I/O modules can be used whenever you are looking to integrate actuators, sensors or other field units into your automation network.
