Wireless ethernet devices

Leveraging the IEEE 802.11 WiFi standard, Weidmuller's WL-EM-240 wireless ethernet modem provides an increased power output of 300 mW to ensure enhanced signal strength in difficult industrial environments.

The modem can be configured to operate as an access point, client, bridge or repeater. Full routing, redundancy and security capabilities are supported on the unit which is configured via a simple web browser interface.

In addition to the IEE 802.11 unlicensed 2.4 GHz WiFi, Weidmuller also provides a wireless ethernet solution, the WL-EM-900, which utilises the unlicensed 900 MHz band. The benefit of 900 MHz wireless communication is that it provides significantly longer transmission distances; in many instances distances up to 30 km line-of-sight can be achieved.

Both 2.4 GHz and 900 MHz ethernet modems also support separate RS232 and RS485 interfaces, which can be used to provide wireless serial device server capabilities and can be run concurrently with ethernet communications.

Weidmuller also offer the WL-TXRX-900 range of wireless I/O modules that can be used to transfer both analog and digital I/O information from one location to another using 900 MHz wireless technology. Fully configurable as simple point-to-point or point-to-multipoint devices, the WL-TXRX-900 products are available as a separate transmitter, receiver or matched pair.

All these wireless devices are supported by a range of accessories, including Modbus-based expansion I/O modules for the ethernet modems. In addition, a range of antennas, antenna cables and wireless surge protection accessories are available to provide a complete wireless solution to meet specific application requirements.
