PLANET IMG-2400T – 4-Port Industrial Modbus Gateway for TCP/RTU/ASCII Conversion

The PLANET IMG-2400T is a robust industrial Modbus gateway featuring four DB9 serial ports and dual Ethernet interfaces for seamless bridging between Modbus RTU/ASCII and Modbus TCP/IP environments. Designed for industrial automation, SCADA, HMI, and IoT applications, it enables legacy serial devices to operate within modern IP infrastructures.

Equipped with rugged IP40-rated housing, dual 12–48V DC redundant power, and operating in extreme temperatures from -40 to 75 °C, the IMG-2400T is ideal for critical deployments. With digital input/output alarms, remote web/telnet/SNMP management, and up to 32 TCP connections per mode, it offers excellent flexibility, reliability, and visibility for industrial networks.

Key Features:

• Converts Modbus TCP/IP ↔ Modbus RTU/ASCII
• 4 DB9 serial ports: RS232, RS422, 2-/4-wire RS485
• 2 x 10/100BASE-TX Ethernet ports with Auto MDI/MDI-X
• Digital I/O for external alarms (e.g., power fail, intrusion)
• Rugged IP40 metal housing, -40 to 75 °C operating range
• Up to 32 TCP slave or master connections per mode
• DIN-rail and wall-mountable for flexible installation
