Internet of Things (IoT), remote monitoring, and a host of other industrial applications present unique challenges to networking. Field devices must communicate with distant data storage and processing centers. Providing this data path requires a stable connection, ultra-low power consumption, and no hands-on maintenance. The only hope for success comes from remote data transmission hardware. For that purpose, the Robustel M1200-4M smart serial to LTE gateway is worthy of your consideration.

The compact M1200-4M is a simple way to connect your serial devices to the cloud. It provides stable networking that utilizes smart power consumption and effective security. Dual SIM card slots resist downtime by providing primary and secondary LTE channels. Manage security with a VPN tunnel that configures for IPsec, OpenVPN, or L2TP. Perhaps most important of all, the gateway can transmit your serial data across EGPRS, CAT M1, or CAT NB1.

While a secure and stable connection is vital to maintaining remote communications, the gateway also needs to be able to handle the elements. The M1200-4M meets those requirements. It accepts an input voltage range from 9 to 36 DCV. The DIN-rail and flange mounts stabilize the gateway against intense vibrations and enable it to fit into the smallest control panels. The operating temperature range is downright impressive. Anywhere between 40 below or 75 degrees Celsius is no problem for the M1200-4M. If, after all of that, you have any doubts, it is backed by a 5-year warranty.
