Mayfield Heights, O.— Rockwell Automation introduced Sept. 9 a scalable I/O solution that allows users to specify precise numbers of I/O points needed for their applications.

Point I/O consists of terminal bases, I/O modules, and network adapters that are DIN rail mounted and link to meet an application's exact needs. Being able to select the precise number of I/O points required allows users to save panel space and reduce expenses. Point I/O's 12-mm granular modules consume minimal DIN rail space and are designed for installations requiring a mix of I/O types in a small envelope. The modules' I/O density is as high as 3 mm per point.

Point I/O can communicate over DeviceNet networks. It also features removal and insertion under power, which eases installation, troubleshooting, and maintenance.

In other news, Rockwell Automation also recently introduced its Allen-Bradley Zero-Force touch buttons designed to address ergonomic and safety concerns by alleviating potential problems associated with highly repetitive actions. The company says Zero-Force is the first operator interface device of its type to incorporate field effect sensing with microprocessor technology.

Zero-Force features a contoured surface that follows the palm of the hand, which eliminates the need to rotate hands or operate buttons with one finger. This helps prevent carpal tunnel syndrome and other nerve disorders.

Unlike traditional push buttons, Zero-Force buttons don't require pressure for activation. Instead, sensors register the operator's touch using two independent field-effect sensors that convert human touch into an electrical output. Accidental activation is minimized because both sensors must be activated within 0.2 sec. This allows Zero-Force to distinguish between the operator's touch and most foreign objects.
