Industrial communication controllers
June 2, 2010 by Manufacturing AUTOMATION
Advantech introduces the EKI-1121L and 1122L ARM-based Industrial Communication Controllers, which feature a pre-installed embedded Linux operating system for user-developed communications, monitoring and control applications.
These devices are based on an ARM7 SoC (System on Chip), featuring dual 10/100 Mbps Ethernet ports, and one or two serial ports, which are software configurable for RS-232, RS-422 or RS-485. The standard configuration includes 16MB of SDRAM, 8MB of flash, and uClinux (an embedded Linux distribution) pre-installed.
Compared to x86 based systems, the ARM-based design provides excellent performance and extremely low power operation at the same clock speed. Maximum power consumption is 2.5W.
Suited to demanding environments, these controllers are designed to withstand extreme shock and vibration, 4,000 VDC Ethernet ESD protection, 3,000 VDC power line surge (EFT) protection, and they feature redundant 12 to 48 VDC power inputs for resiliency. The EKI-1221L an 1122L are packaged in a metal IP30 rated chassis and include DIN-rail and direct panel mounts for easy installation.
