The advanced EKI-1220 series Modbus Gateways support 16 TCP masters, 16 TCP slaves. Each serial port supports up to 31 RTU/ASCII slave devices. Dual Ethernet ports allow the EKI-1220 series to establish two separate physical Ethernet connections. This enables redundancy back up if one connection is broken or lost. The EKI 1200 series also has 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, the EKI-1200 series is built in a compact and thin DIN-rail mount form factor with an IP30 metal housing, 3000V DC surge protection for the power line plus 4000 V DC ESD protection on the Ethernet ports.
Operating temperatures scale from 0 to 60c. Under any rigorous environment conditions, the EKI-1221, EKI-1222 and EKI-1224 provide non-stop operations with advanced features and user-friendly designs.
