Advantech ECU-1251 IIOT Gateways

Advantech ECU-1251 IIOT (Industrial Internet of Things) Gateways are RISC-based gateways optimized for factory and industrial applications requiring a total wireless and Ethernet communication solution. The ECU-1251 Gateways feature an open platform design with a Cortex® A8 Processor, up to four RS-232/485 isolated serial ports, two 10/100 Ethernet ports, and an operating temperature range of -40°C to 70°C.

The Advantech ECU-1251 Gateways are offered with RT-Linux, with variants including TagLink Studio (ECU-1251TL-R10AAE) or WISE-EdgeLink SDK (ESRP-PCS-ECU1251), enabling system integrators to develop applications that precisely fit the application's needs.
