Expert Electronic’s WLAN switch is a universal switch controlled via a wireless WLAN connection. It is perfect to use when its impossible to run cables for remotely located, power switches, antenna switches etc. It is a crucial accessory to include when building a remote station.
Using the WLAN 802.11 b/g/n standard lets you include the WLAN switch in already existing wireless networks. The WLAN switch is based on the famous, miniature WLAN module ESP‑07E, it combines open architecture, good usability, and opportunity to program the module firmware by yourself.
The unit consists of a miniature WLAN module with an external antenna, power stabiliser, and galvanically isolated control switches based on opto-relay.
EE WLAN Switch main capabilities
- Remote control of external DC circuits with voltage up to 100 V and current up to 300 mA.
- Connect up to 12 active circuits.
- Several ways to control the load: closing of the normally opened switch, voltage output when the switch is on, closing of the switch contact on the case – pin connected to GND.
- Using several WLAN switches simultaneously in the same system/network.
- Update WLAN module firmware via internal USB-COM converter.
- Operation in a wide range of supply voltages from 8V to 20V DC and from 12V to 20V AC.
- Convenient web-interface for WLAN switch control.
- Open platform, you may create your own software for the internal module.
- Main PCB covered with several layers of translucent plastic (done at manufacture) to protect it from moisture, corrosion, etc.
