From sensors and actuators towards control system: ERNI Electronics have expanded their M8/M12 product line by passive I/O distribution boxes. The M8/M12 I/O connectors distribution box is available from Erntec .

Complementary to M8/M12 cable assemblies and field-attachable connectors suitable for industrial use, with I/O distribution boxes ERNI offer another element of the information chain between field devices and control level. Distribution boxes bundle signals from sensors/actuators and establish uplink to the control system.

The I/O modules are well accepted within industrial automation not least because they avoid parallel cabling and complex installation towards control units or switch cabinets. Instead of using numerous single cables, sensors and actuators can be directly connected in close vicinity to the machine or process. This concept is simple, efficient and cost-effective.

The usage of common connection technology and standard interfaces allows for:

  • reliable connections
  • safety in the automation solution
  • highly available field devices


The idea of decentralised modules and a more structured installation enables sensor/actuator lines to be easily, quickly and faultlessly replaceable. Hindering cable loops are then a relict of the past. Efficient cabling minimises downtime of machine or equipment and enables flexibility at installation and maintenance. This saves both time and money and consequently assures competitive advantages.

All distribution boxes of the product range are designed for IP65/IP67 protection and hence are predestined for use in harsh and humid industrial environments. The housing available in various port numbers is built in a compact and robust way; fully encapsulated, it withstands vibration to a high extent.

Various mounting holes allow for direct attachment on the machine and thus ensure close installation to the process. The connection to the control level is realised by a pre-assembled trunk cable available in different standard lengths. Designed as hybrid cable it is both power supply and data link for sensors and actuators connected to the I/O box.
