Industrial Computing - New Generation of Modbus Data Gateways
EKI-1221/1222/1224
Taipei, Taiwan - September, 2008
The Industrial Automation Group of Advantech is proud to release the advanced EKI-1220 Modbus data gateway series, featuring fast 1, 2 or 4 RS-232/422/485 serial ports with 2 x Ethernet ports. EKI-1221, EKI-1222 and EKI-1224 Modbus data gateways support Modbus RTU/ASCII master and slave modes simultaneously, with high speed data transfer rates and dual LAN redundancy, providing the most modern and reliable Modbus Data gateways available.
Advanced Modbus Gateway Functionality
Last generation Modbus gateways have low baud rates and only support Modbus RTU/ASCII slave mode. Advantech's EKI-1220 Modbus data gateway series provides 921kbaud speeds and are designed to fulfill any master/slave relationship. Moreover, the advanced EKI-1220 Modbus data gateway series supports 16 TCP masters, 16 TCP slaves, and each serial port supports up to 31 RTU/ASCII slave devices. In other words, the EKI-1224 has 4 serial ports supporting up to 124 devices.
Simultaneous Dual LAN Redundancy
Dual Ethernet ports allow the EKI-1220 series to establish two separate physical Ethernet connections so that if one of the connections is broken, the Modbus gateway will switch to the other connection automatically. This idea of 'redundancy' within a network can guarantee that devices will always be connected and that information will never be lost.
Industrial Design for Demanding Applications
EKI-1221/1222/1224 also have built-in dual power inputs (DC 12~48V) with 1 power fail relay output to detect power operation status and ensure reliable operation. Like other members of the EKI Industrial Ethernet family, EKI-1221/1222/1224 are built in a compact and thin DIN-rail mount form factor with an IP30 metal housing, 3000 VDC surge protection for the power line, plus 4000 VDC ESD protection on the Ethernet ports, and feature an operating temperature range of 0 to 60° C. Under any rigorous environment conditions, the EKI-1221/1222/1224 provide non-stop operations with advanced features and user-friendly designs.
