Key Features

• Dual isolated serial ports enable simultaneous communication with multiple devices or networks
• Supports both RS-485 and RS-232 on each port via DIP switch configuration
• Operates as a Modbus RTU master to control drives, meters, and remote I/O, or as a slave for integration into larger control systems
• Facilitates peer-to-peer data exchange between GE PLCs using DF1 protocol
• High-speed data transfer up to 115.2 kbps ensures timely response in real-time applications
• Optical isolation provides protection against electrical noise, ground loops, and voltage transients
• Flexible protocol support allows integration with third-party devices from various manufacturers
• Independent port configuration supports different baud rates, data formats, and protocols on each port

Application Areas

• Industrial automation systems based on GE Fanuc Series 90-30 PLC platforms
• Integration with HMIs, SCADA systems, and operator terminals over serial links
• Connection to variable frequency drives (VFDs), servo controllers, and intelligent sensors
• Data logging and reporting via serial printers or external data recorders
• Machine and process control systems requiring concurrent communication with multiple devices
• Water treatment, manufacturing, and energy facilities using legacy serial infrastructure
• Retrofit and system expansion projects involving serial-based field equipment
