Parker Hannifin has released pneumatic valves that meet ISO standard 15047 parts 1 and 2 (ISO sizes 02, 01, 1, 2 and 3). The IsysNet system is based on a modular construction, using quick-fit latching mechanisms that enable valve, I/O and communication modules to be installed on common manifold units in seconds and without the need for extra connector plates. In addition, modules can be reconfigured on site, while serial modules can be changed even when the system is powered up and without affecting the controlling software. I/O modules are also colour-coded for quick identification. The serial modules use a fast backplane with the latest change of state connections which allow an IsysNet manifold unit to be linked directly to sensors, limit switches and encoders and to remotely operated solenoid valves or other pneumatic devices. The IsysNet system provides a choice of digital, analogue and high-wattage I/O, with individual modules incorporating comprehensive safety features such as short circuit and open circuit detection. The system can be extended considerably using communication modules, which support up to 62 I/O modules and up to 252 inputs and 252 outputs. Both electronic and pneumatic connections are built into a single manifold-mounted end plate.
