ASCO Numatics G3 valve island with modular flexibility for minimal plant disruption

13 February 2012

Latest G3 ‘plug and play’ platform with multiple protocols features a unique graphic display that supports plain-language messaging for diagnostics and set-up

ASCO Numatics G3 fieldbus next-generation, electronic platform valve island, is easy to assemble, install, commission, and maintain, and features a graphic display for easy commissioning, visual status and diagnostics. With its modular flexibility and choice of communication protocols, the G3 valve island has many applications in in the food processing industry for packaging machinery, conveyors, robotics and valve piloting.

Communication protocols supported include DeviceNet™, DeviceNet™ w/Quick Connect, EtherNet/IP, PROFIBUS-DP, CANopen, PROFINET, MODBUS/TCP, DeviceLogix, and Powerlink. The G3 electronics interface with the highly modular Numatics generation 2000 Series, ISO 5599/2 and ISO15407-2 Series valve lines, to further enhance the modularity and flexibility of the entire system solution.

The G3 valve island offers increased intelligence in the form of new diagnostic functions and enhanced plug-and-play capabilities for individual modules. The graphic display (in place of the usual LED indicators) supports plain-language messaging of diagnostic information at both the module and communication node level. The messages give the user direct information and this makes it easier to detect shorted and open load, shorted sensor/cable, low and missing power, and missing module. It also allows self-test activation and provides a log of any network/distribution errors.

The G3 Series product line is a completely modular system. Protected to IP65/NEMA 4, the G3 electronic modules plug together, using an innovative clip design, allowing easy module removal/replacement without dismantling the whole manifold. This makes the system highly user friendly. Additional flexibility is incorporated because the same modules can be used in either centralised or distributed applications.

SPEEDCON M12 connector technology allows for fast and efficient ½ turn I/O connector insertion and the power connector scheme allows the output power to be removed while inputs and communications are left active. An Auto Recovery Module (ARM) protects configuration information during a critical failure.

The G3 supports up to 256/544 inputs/outputs with one communication node of up to 32 valve solenoids per manifold and up to 16 manifolds per communication node. One node supports 16 I/O modules-analogue I/O, digital I/O (NPN & PNP) and the unique distribution system allows system efficiency by allowing the same modules to be used in either centralised or distributed applications. The G3 interfaces to valves with flow from 275 up to 3820 l/min ANR.
