Cleveland-based Parker Hannifin recently added its P2H IO-Link node capabilities to the company’s ISO valve platform. The P2H node reportedly provides a robust means of connecting H Series valves to an IO-Link network, thus saving total system and installation costs in comparison to the use of Ethernet or hard wiring. In addition, the P2H IO-Link node is safe-power capable, meaning auxiliary valve power can be supplied by a safety device in support of the European Machinery Directive.
P2H IO-Link node brings a general purpose industrial valve into the IO-Link portfolio, and yet maintains the ability to mix flow sizes on a Universal manifold base. The P2H IO-Link node complements Parker’s other IO-Link products, which are focused on reducing complexity and cost at the machine while supporting the simple diagnostics principles of smart factory and Industry 4.0 concepts.
The product is suited for markets such as general industrial, automotive, materials handling, steelmaking, packaging and plastics. The P2H IO-Link node is a 24-output module, available in both Class A with a 7/8-in. power In/Out connection for an independent auxiliary power supply — an industry first for an IO-Link valve device — or a Class B version with power and communication over a single five-pin M12 connector. It provides local diagnostic input data such as voltage monitoring, temperature warnings and communication error via the network. These capabilities simplify diagnostics and support predictive maintenance strategies.
With its strong glass-filled PBT housing, the node offers weld-spatter resistance, UV protection and flame retardant properties. As a result, P2H is designed for applications such as vehicle body welding and assembly processes. Further typical uses include systems for the application of adhesives and sealants, end of arm tooling (EOAT), riveting, blow molding machines and case erectors. In terms of configuration, up to 24 solenoid addresses can be accommodated per manifold mixing HB, HA, H1 and H2 valve sizes thanks to the H Universal manifold design.
Parker’s H Series ISO valve now features a full range of connectivity options, including IO-Link, Ethernet/IP, Profinet IO, EtherCAT, POWERLINK, Modbus/TCP, DeviceNet, ControlNet, Profibus DP, CANopen, AS-I and InterBus-S. Customers requiring a collective hard-wired solution can connect with 25 Pin’s D Sub, 19-pin Brad Harrison or 12-pin M23 connections. For rigid conduit, a terminal box is also offered.
