Avoiding the use of parallel cabling and installation involving control units or switch cabinets, ERNI Electronics’ M8/M12 line of passive I/O distribution boxes allow for the direct connection of sensors and actuators. The UL- and CSA-approved devices are designed for IP65/IP67 protection, and are built for use in harsh and humid industrial environments. The M8 boxes are available with 3-pin and 4-pin sockets and with 4, 6, 8 and 10 ports, while the M12 boxes ship with 4- and 5-pin sockets (A coded) and 4 respective 8 ports. All units utilize LEDs to display the status and operation mode of the I/O ports, and every port is equipped with a removable identification label. PUR insulated cables come in standard lengths of 3 m, 5 m, 10 m, and 15 m, and the drag chain-capable cables demonstrate resistance to oil, gasoline, chemicals, and abrasion.
