Compact design M2M Industrial Cellular Modem , RS-232 serial to 3G IP

Description

The WLINK D803 series of industrial trid-band 3G terminal are designed to transmit data and short messages (SMS) over GSM / GPRS/3G mobile networks. The modems can be used to increase the efficiency of maintenance and communication, but do not require extensive training. In addition, the modems can be mounted on a DIN rail or wall.

The D803 series modems accept a 5 to 48 VDC power input, making them suitable for use with a variety of field power sources. The serial ports feature 15 kV ESD line protection to protect the products from harmful electrical discharge.The serial interfaces on the D803 make it ideal for attaching all kinds of devices, such as stand-alone controllers, PC COM ports, and multi-dropped electric meters. In addition, the D803 has an extended operating temperature (-25 to 70°C) design that makes it suitable for heavy industrial use.
