Munich, Germany " Erni Electronics has expanded its M8/M12 connector product line with the introduction of a line of passive I/O distribution boxes. The I/O modules are highly utilized in the area of industrial automation, for they avoid the use of parallel cabling and complex installation involving control units or switch cabinets. Instead of using numerous cables, sensors and actuators can be directly connected for quick and easy installation or replacement.
I/O modules reducing cabling in industrial automation
All ERNI M8/M12 distribution boxes with UL/CSA approval are designed for IP65/IP67 protection, and are built for use in harsh and humid industrial environments. The housing is available in a variety of port numbers and is robustly built to withstand oil, lubricants and vibration in the harshest of environments. A range of mounting holes gives the option of direct attachment, and ensures the close proximity of the installation to the process. The control level is connected by a pre-assembled trunk cable available in different standard lengths. Designed as a hybrid cable, it acts as both the power supply and the data link for sensors and actuators connected to the I/O box.
The M8 I/O boxes are available with 3-pin and 4-pin sockets and with 4, 6, 8 and 10 ports, and the M12 I/O boxes ship with 4- and 5-pin sockets (A coded) and 4 respective 8 ports. All boxes utilize LEDs to display the status and operation mode of the I/O ports, and every port is equipped with a removable identification label. ERNI supplies PUR insulated cables in standard lengths of 3, 5, 10 and 15m. The cables demonstrate a high resistance to oil, gasoline and chemicals, and are abrasion resistant and drag chain capable.
