Modems

Industrial Modems — New & Used

Industrial modems enable secure communication between machines, remote sites, SCADA systems and OT/IT networks—using cellular, satellite, radio or wired links. They support remote telemetry, machine-to-machine (M2M) connectivity and IIoT deployments in challenging industrial environments.

At Surplus Select, we maintain a curated inventory of new and used OEM industrial modems, including cellular routers, satellite gateways, radio modems and wired telemetry units. Our surplus pricing offers cost-effective connectivity solutions for system integrators, OEM builders and remote-site operators who need reliable data links without paying full catalog cost.

Price Match — We match any authorized distributor on identical in-stock parts, so you can source parts at surplus pricing with distributor-level assurance.

Trade-In Credit — Have quality new surplus items? Trade them in for store credit toward the parts you actually need.

Fast U.S. Shipping — Most orders ship same or next business day from our U.S. warehouse to keep your line running.

Find Your Industrial Modem Fast (Search-First)

Search your part number or model (e.g., MCR200-4G-LTE, cellular router industrial 4-port, radio modem 900 MHz 10W).
No PN? Try specs like "industrial cellular modem 4G LTE CAT-6", "satellite modem Iridium data link", or "LTE router dual-SIM industrial grade".
Need a specific connectivity or rating? Add terms such as dual SIM, IP67, DIN rail, EtherNet/IP, or modbus gateway to your search.

Applications & Use Cases

Remote SCADA & telemetry: Use industrial modems to connect remote pump stations, substations, and field-sites to central control systems via cellular, satellite or radio networks.
Machine-to-Machine (M2M) connectivity: Enable OEM machines in factory or mobile environments to transmit data, alerts and diagnostics over wired or wireless links. ([iot-agenda.com](https://internetofthingsagenda.techtarget.com/definition/M2M-machine-to-machine?utm_source=chatgpt.com))
Industrial IoT & edge-computing: Deploy modems and gateways to aggregate sensor and telemetry data, support remote firmware updates and integrate with cloud analytics. ([techtarget.com](https://www.techtarget.com/iot/definition/edge-computing-edge-systems?utm_source=chatgpt.com))
Rail, oil & gas, utility networks: Industrial modems provide rugged communications in harsh environments—on-board equipment, pipelines, substations and remote locations.
MRO & retrofit networks: Replace legacy modems or upgrade connectivity platforms with surplus OEM modems to reduce cost and maintain connectivity-reliability without paying full new cost.
