New G3 fieldbus electronic platform valve island is 'easy' all round
26 April 2010
ASCO Numatics' new G3 fieldbus electronic platform valve island is easy to assemble, install, commission, and maintain, and features a graphic display for easy commissioning, visual status and diagnostics. The robust connections are quick, easy to use and make the platform highly distributable.
The new 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.
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 512 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.
Protocols supported include DeviceNet, DeviceNet w/Quick Connect, EtherNet/IP, PROFIBUS-DP, CANopen, PROFINET and MODBUS TCP. The G3 electronics interface with the modular Numatics generation 2000 Series, ISO 5599/2 and ISO15407-2 Series valve lines.
