Connecting Rockwell Logix control systems to an AS-interface network has never been simpler with the introduction of Molex's new Brad SST Actuator Sensor Interface Modules. The AS-i modules provide an open fieldbus solution enabling an easy connection between the PLC backplane and simple field I/O devices such as actuators, sensors, rotary encoders, analogue inputs and outputs, push buttons, and valve position sensors.

Designed for chassis mounting, the AS-i communication modules can interface with signals coming from AS-i field devices, transfer that information to the PLC and send control information back to the AS-i actuator. Meeting the new AS-i specification 3.0, the AS-i communication modules are also compatible with legacy versions as well as the very latest AS-i products. They also feature a fast AS-i cycle time, which is ideal for high-speed, machine control applications.

“One of the most outstanding benefits of the AS-i modules is the simple and easy installation process due to the two push button design and integrated display,” commented George Kairys, global product manager, Molex. “Ultimately, this speeds up the commissioning process so that downtime, whether it is planned or not, is minimised.”

The modules come bundled with cables and configuration software, and include diagnostics that help identify configuration errors and network faults, further reducing commissioning and downtime. These modules are ideal for multiple industrial automation applications, including conveyor control, packaging machines, process control valves, electrical distribution systems, airport carousels, elevators, bottling lines and food production lines.
