Fiber-Optic Link to EIA-485

Connect to two- or four-wire EIA-485 network segments with SEL-2824 Fiber-Optic ST Transceivers and an SEL-C808 Multimode Fiber-Optic Cable. The SEL-2824 uses an ST connector, is compatible with the SEL-2814 Fiber-Optic Transceivers With Hardware Handshaking, and supports a link distance of 1 m to 4 km (3.3 ft to 2.5 mi).

Fast Data Rates

Transfer data at rates up to 115 kbps with the SEL-2824, which transfers data and hardware flow control signals.

Safe and Secure

Install fiber-optic connections to isolate communications from ground potential rise and electrical interference.

SEL-2824 Details

Increases Safety
Isolates devices from ground potential rise and fault current in the communications connections by using optical fiber instead of wire. Improves Signal Integrity
Prevents electromagnetic interference and signal ground loops by using optical connections instead of copper wires. Withstands Harsh Conditions
Operates over –40° to +85°C temperature range and meets or surpasses electric utility and industrial type-test standards for instrumentation, control, and communications equipment. Easily Applied
Implements fiber-optic links between two- and four-wire EIA-485 network segments. Set operating modes via control (DIP) switches. Simplifies network commissioning and repair with LED traffic indicators for each port. Connect power through terminal block or jack.
