BLE / RS485 Gateway Central

WM-262E

Building-in advanced BLE can resist the external interference and perform the serial communication. In addition to enabling to communicate between Central and Peripheral, it can be connected by the mobile phone, tablet and other Bluetooth host device.
RS-485 MODBUS RTU’s industrial interface is available that can connect to the existing industrial control host (ex. PLC). Also provides RS-232 to allow users to connect devices with different interfaces.
Supply 5V DC/200mA output power for use in external subunits, which is much suitable as the basic equipment for the industrial Internet of things.

Features

• BLE to RS-485 MODBUS RTU gateway.
• 2 way wireless RS-485 bridge (between Peripheral and Central).
• Small and waterproof design.
• Built-In or external antenna.
• Wide voltage operation.
• RS-485 interface.
• AUX Power output for general purpose such as plug-in sensor, or other sub system.
