Norton adds that all connectors use CAGE CLAMP spring-pressure termination technology for maintenance-free wiring that is vibration-proof, corrosion-resistant, thermal cycling-resistant, and up to 50% faster than wiring with screw technology. The 753 Series pluggable I/O modules are said to be 100%-compatible with the original 750 Series I/O modules and bus-couplers. Consequently, customers can mix both 750 Series and 753 Series in the same I/O node. This allows customers to choose whether or not to make all functions on the node pluggable or to keep some functions that should not be tampered with as non-pluggable. “Another useful reason for having both pluggable and non-pluggable I/O wiring is to indicate which of the I/O modules are wired to devices internal to the control cabinet--contactors or relays, for example--and which ones are wired to devices such as sensors and actuators on the machine, external to the control cabinet,” adds Norton.Compatibility with the 750 Series also gives these I/O modules complete access to Wago’s extensive line of fieldbus bus couplers. The offering includes ECO couplers, a lower-cost solution for highly distributed applications; the original couplers, which allow connection of up to 256 I/O points in a combination of digital, analog, and special function I/O; and the programmable fieldbus couplers that offer full PLC capability in both standalone or distributed control applications. In addition, the couplers are offered in a variety of protocols including Ethernet TCP/IP, EtherNet/IP, DeviceNet, Profibus, Modbus, CANopen, and more.“By developing the 753 Series pluggable I/O modules, and making them compatible with the 750 Series,” concludes Norton, “Wago is helping to provide fieldbus users the utmost in flexibility--whether in wiring options, fieldbus selections, modularity, granularity, or signal types.”
