A2W Wireless Controller Master Units

Published on : Tuesday 30-11--0001

Omron Automation A2W Wireless Controller Master Units perform master-slave wireless communications with A2W Wireless Pushbutton Switches using the sub-GHz band. This is realized by sending ON/OFF data from the pushbuttons to the Master Unit and responding reception confirmation to the pushbuttons from the Master Unit. Manufacturing sites require more versatile and flexible production systems due to the frequent changeover of low volume production. These controller master units support multiple switches/connections (up to 8) with a focus on decentralized control. The A2W wireless pushbutton switches and controller master units use 922.5MHz frequency band to reduce interference and provide a better signal in locations with obstacles.

The A2W Wireless Controller Master Units accommodate visualization of impedance to wireless transmission due to damage or noise using error output. The transistor output from the Master Unit is a one-shot operation. High-sensitivity magnetic-base antenna is provided to place the antenna in a position avoiding obstacles. This antenna is available for installing the Master Unit inside a control panel.

Features

• Up to 8 Pushbutton switches can be assigned to one Master Unit
• Sub-GHz band for reduced interference and better signal propagation to difficult-to-reach areas
• Transmission distance independent of the transmission position of the pushbutton
• The transistor output from the Master Unit is a one-shot operation (500ms)
• Visualization of impedance to wireless transmission because of damage or noise using Master Unit error output
• Each unit comes with a free PC software tool for easy setup
• Output points:

1. 8 outputs
2. One for error output

• High-sensitivity magnetic-base antenna is an option when installing the receiver inside a control panel

Applications
