- IEEE C37.94 Standard Conversion
Converts electrical teleprotection interfaces to the IEEE C37.94 optical standard. Connect an SEL-3094 to an ITU-T G.703, EIA-422, EIA-485, or EIA-232 device, and use up to 2 km of optical fiber to link to a C37.94 multiplexer. Similarly, replace a G.703, EIA-422, EIA-485, or EIA-232 wire link with fiber, connecting a noncompliant multiplexer to a teleprotection device through a pair of SEL-3094 interface converters.
- Easy Application
All settings are made with ten control switches. LEDs indicate the state of inputs, outputs, and the communications link
- High Speed
Uses one 64-kilobit time slot in a digital multiplexer.
- Improved Safety and Isolation
Fiber-optic connections provide isolation from dangerous ground potential rise, prevent induced electrical noise, and eliminate signal ground loops.
- Universal Power
Power supply operates from 18 to 300 Vdc and 85 to 264 Vac.
- Dual Side-By-Side Kit
Order the SEL-9921 combination package for two SEL-3094 Interface Converters connected by a side-by-side mounting bracket for a standard 19 inch rack. The bracket enables removal and installation of one SEL-3094 without taking the other one out of service, so one converter and communications circuit of a dual primary or primary-backup scheme remains in service while you are working with the other one.
