The OnCell 5004/5104 are high-performance industrial grade cellular GPRS routers. The difference between the OnCell 5004 and OnCell 5104 is that the OnCell 5104 comes with a built-in relay output and two digital inputs allow you to connect basic I/O devices, such as sensors, to the cellular network.
The OnCell 5004 can be placed on a desktop or wall-mounted, whereas the OnCell 5104 has an IA design and can be attached to a DIN-rail. Both products use 12 to 48 VDC power inputs with a screw lock for greater reliability, and the Ethernet ports come with 1.5kV magnetic isolation protection to keep your system safe from unexpected electrical discharges.
