"It is an encapsulated device that is used to gather a mixture of input/output signals on a machine. Because it is IP69K-rated, it can withstand environmental exposure," says Karen Keller, strategic marketing manager, TURCK Inc. The I/O connection enabled by this device is "contrary to the hard-wiring of all devices back to the control cabinet. Junction boxes provide similar functions to that of the BL Compact, but a standard junction box can only accept one type of signal."
Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over EtherNet/IP, DeviceNet, CANopen and Profibus. The device's small size and IP69K-rated housing allows it to be placed on the machine closer to the signals.
The BL Compact system can be customized so that as devices are added to an existing network, signals can be gathered on the machine without adding a separate enclosure. The ability to connect up to 16 devices drastically reduces the time it takes to run wires for each device back to the control cabinet, as well as reducing the potential for wiring errors.
The BL Compact system is currently available with four, eight or 16 ports in an environmentally hardened package rated for IP68 and IP69k protection. M8 or M12 connectors for bus communication and auxiliary power facilitate installation into any new or existing application.
