The company has released four modules, with plans for a fifth in the works, all designed to be configured to function just like a variety of individual analog cards, and all for a cost of less than half a single card. The PWD00A-400 can drive Parker open-loop proportional valves with ramps and setpoints as standard parameters. The PCD00A-400 can drive standard open-loop throttle and pressure control valves, also with ramps and setpoints as standard parameters. The PWDXXA-400 drives high-performance valves with spool feedback, and the PZD00A-400 replaces accessory cards. The PID00A-400, currently in beta testing, processes external closed-loop control of cylinder position, pressure and velocity, providing +/- 50 mA direct servo drive. All models are configurable with free interface software, snap on a standard DIN rail, and use plug-in electrical connectors.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Microchip recently released the 3D TouchPad, the first USB PC Peripheral device that couples 2D multi-touch input with 3D air gesture technology. The company seeks the help of developers to further enhance the capabilities of the technology.
