FAQs
The EGR-5000-2B0IA1 uses removable terminals and projection mounting for straightforward wiring and mounting in common generator enclosures. With 8 digital inputs, 9 outputs, 2 analog inputs, and 2 analog outputs, it fits typical protection schemes without extensive panel redesign, reducing retrofit time and minimizing field wiring errors.
Key performance specs include 50/60 Hz operation, power supply range of 19–300 Vdc and 40–250 Vac, 8 DI/9 DO, 2 AI/2 AO, and RS-485 Modbus plus Ethernet connectivity. It also supports URTD Interface Trip Coil Monitor IRIG-B for time synchronization, enabling accurate protection timing and integrated monitoring across control systems.
Yes. Its robust I/O structure, flexible power input range, and multiple communication options (RS-485 Modbus and Ethernet) make it well suited for industrial protection schemes, plant-wide monitoring, and remote diagnostics. It supports generator protection logic, fault alarm signaling, and fast trip decisions essential for mission-critical facilities.
Compliance status is provided by the manufacturer; confirm CE, UL, or SIL readiness with Eaton for your installation. The product overview lists 'Compliances: Contact Manufacturer', so validation of regulatory certifications should be requested during procurement to match site requirements.
Integration of 8 DI/9 DO and 2 AI/2 AO with RS-485 and Ethernet reduces external relays and wiring, cuttinginstallation time and panel space. Remote monitoring and time-synchronized diagnostics lower downtime, while the warranty and service policy support predictable maintenance schedules, translating to lower total cost of ownership over the asset life.
