Rockwell Automation is expanding the Allen Bradley 1799 Embedded I/O product line for conveyor applications. These new I/O units are designed for conveyors that need to be networked and still provide high-speed and precise local I/O response times. Each unit consists of I/O circuits, a power supply and network adapters, all mounted in a single, low-cost IP00 module that provides local control of outputs using DeviceLogix technology.
The Series B 1799 Zone Control Modules deliver the same low-profile form factor, high-speed I/O execution and usability found in the current line of On Machine Embedded I/O modules, with the added features of expanded function block capacity and password protection. The built-in DeviceNet communications links the machine to the controller for increased speed and efficiency.
Jim Vargo, product marketing manager, Rockwell Automation, comments: "Customers that distribute On-Machine Embedded I/O in material handling applications can enhance communications using the zone control cards to help reduce costs and simplify installation. One card can consume data directly from up to four other zone control cards without going through a PLC scanner, which is excellent for merge or divert applications."
As part of the 1799 Embedded I/O product line extension, the modules include DeviceLogix with analogue functions for speed synchronisation and lower overall system costs.
