Description
The Comnet is serial data link/repeaters are substation-rated and industrially hardened form, fit, function and completely backwards-compatible replacements for the popular Garrettcom/Dymec 5843, 5844, 5845, and 5846-series of serial data link/repeaters. They are designed for deployment in environments where high levels of electromagnetic noise and interference (EMI) and severe voltage transients and surges are routinely encountered, such as electrical utility substations and switchyards, heavy manufacturing facilities, trackside and roadside electronic equipment, and other difficult out-of-plant applications. Optical connectivity provides significantly extended transmission distances compared to copper media; high levels of electrical isolation; enhanced reliability and protection for peripheral IEDs, RTUs, and other equipment; and
operational safety. The serial data link/repeaters are easily field-configurable for point-to-point, pointto-multipoint/master-slave, loop, or bus topologies. They may be also used for electrical data protocol conversion: an RLFDX232 RS-232 modem and IED/RTU can communicate directly with an RLFDX485 RS-422/RS-485 modem and IED/RTU.
The extremely versatile and simple-to-install RLFDX series is ideal for any mission-critical application where very high levels of reliability and network availability are of the utmost importance.
Features
- Fully electrically, mechanically, and optically identical to and backward-compatible with the Garrettcom/Dymec 5843, 5844, 5845, and 5846 Series. A ComNet RLFDX may directly replace a Dymec unit anywhere within the network
- Full-duplex, half-duplex, or simplex transmission of RS-232, RS-422, RS-485 2/4-wire data, or TTL logic
- Tested and certified to meet or exceed the requirements of IEEE 1613 Class 2 for electrical utility substations
- RS-232 Version: DTE/DCE switching
- Diagnostic test mode feature tests the copper and optical connections before the connected IED or RTU is active within the network
- Extended ambient operating temperature range of -40º to +85º C, with no fan/forced air cooling, for use in virtually any environment
- Optical transmission distances of up to 5 km over multimode fiber; 30 km over single-mode fiber
- Internal/self-contained high-reliability power supply – a screw terminal block connects directly to the power source for permanent, reliable, and maintenance-free operation
- LED status indicators confirm operating status
- Rugged galvannealed and powder-coated panel-mount enclosure
- IP-30 rated for ingress protection (2.5 mm objects)
- Conformal coating of the circuit boards is optionally available, for use in humidity with condensation conditions (extra charge, see ordering information)
- Made in the USA
