Eaton transformer relay ETR-5000-2A2FA1 - Modbus RTU over Fiber

Eaton ETR-5000-2A2FA1 is designed to fit a broad range of protection schemes while simplifying installation and maintenance. Feature → Business Impact → Application: Flexible power supply range of 19-300 Vdc and 40-250 Vac supports diverse plant architectures, reducing the need for multiple converters and enabling quicker retrofits in legacy substations. This translates to reduced capital expenditure and faster project delivery for transformer protection upgrades in manufacturing facilities and process plants. Feature → Business Impact → Application: Modbus RTU or DNP3 RTU communications over fiber optic ST delivers secure, interference-free remote monitoring and control, enabling centralized diagnostics and faster fault isolation across distributed energy assets in data centers and utility-scale installations. Feature → Business Impact → Application: 8 digital inputs, 9 digital outputs, and 2 current sensing inputs provide rich protection logic, metering, and control channels, which reduces external hardware count and accelerates commissioning in switchgear and transformer yards. Feature → Business Impact → Application: I/O options such as IRIG-B, Trip Coil Monitor, Sensitive Ground Input, and URTD Interface support precise time synchronization, fault detection, and advanced protection coordination, improving reliability in high-security environments like critical infrastructure facilities. Feature → Business Impact → Application: Removable terminals and projection mounting simplify installation and field servicing, enabling quicker replacements and safer upgrades in cramped or retrofit environments.
