Remote Terminal Unit (RTU / FRTU)

Netcon 200: A compact, all-in-one smart feeder RTU tailored for medium-voltage (MV) secondary substations. It is optimized for feeder switching, fault detection, power quality monitoring, and secondary grid automation.

Netcon 500: A modular, high-capacity RTU and substation gateway designed for larger secondary and primary substations. It handles complex automation, protocol conversion, high-density I/O configurations, and system redundancy.

Both series act as multi-functional devices serving as:

• Remote Terminal Units (RTU) for physical I/O monitoring and control

• Communication concentrators and protocol converters

• Substation gateways connecting field devices to SCADA systems

• Automated controllers running local Programmable Logic Controller (PLC) logic

Both series support standard utility and industrial automation protocols, including:

• IEC 60870-5-101 / 104 (Serial & IP SCADA communications)

• IEC 61850-8-1 (Substation Automation Standard)

• DNP3 (Serial & Ethernet)

• Modbus (RTU & TCP)

Yes. Both devices support multi-master and multi-protocol SCADA communication simultaneously, allowing seamless integration into master systems over cellular networks, Ethernet, or serial lines. 

Both series adhere to IEC 62351 standards for cyber-secure SCADA communications. Built-in defenses include:

• Port hardening and an internal stateful firewall

• Secure boot and digitally signed firmware patches

• Multiple encrypted VPN tunnels

• Role-based Access Control (RBAC) and security logging
