SEL SEL-3031 Serial Radio Transceiver

SEL-3031

Serial Radio Transceiver

The SEL-3031 is a 915 MHz ISM serial data radio that supports point-to-point (P2P) and point-to-multipoint (P2MP) operational modes. In P2P mode, the SEL-3031 supports three serial data ports in one radio channel.

The ports are completely independent and support a mix of protocols, including DNP3. Modbus, Mirrored Bits communications, SEL Fast Message, plain ASCII, and more.

In P2MP mode, a one-channel master radio communicates with multiple remote radios for supervisory control and data acquisition (SCADA) or other data-gathering applications.

SEL Hop-Sync technology optimizes collocated radios applied as multiple point-to-point links or as active repeaters.

The SEL-3031 is a low-power device using less than 5 W in the wall-mount version, allowing it to be incorporated into recloser controls, such as the SEL-651R.

A standard 1 RU high rack mount version is also available, all backed up by SEL’s worldwide, ten-year product warranty.

Dual Radio Operating Modes Provide Flexibility

Gathers SCADA information from remote locations with P2MP radio operation or rapidly transfers critical control and protection commands with low-latency P2P radio operation.

Three Ports in One Radio Reduce Costs

In P2P mode simultaneously communicates with up to three independent ports and protocols (IPP).

In electric utilities, for example, between distributed generation and the point of common coupling, use one channel for teleprotection, another for the electric utility SCADA, and one for the IPP SCADA.

SEL-3031

Similarly, in oil and gas operations, control and monitor the remote infrastructure of your facilities, including oil terminals, storage tanks, water intakes and outflows, pipeline terminals, cooling towers, and more.

Low Latency Enables Fast Control

Transfers control commands with a typical 5.5-millisecond latency with SEL Mirrored Bits communications.

Strong Security Thwarts Attackers

Protects critical data and repels malicious attacks with optional encryption card, using session authentication and strong 256-bit AES technology.

Tough Radio Operates in Extreme Conditions

Designed, built, and tested for trouble-free operation in extreme temperature, electromagnetic interference, shock, and vibration conditions.

No Licensing Reduces Delays and Expenses

Operates on the license-free, 915 MHz ISM band for on-time, on-budget projects.

Precise Time Simplifies Analysis

Synchronizes the internal clock to IRIG-B for accurately time-stamped event logs.

Power Line Teleprotection

Apply communications-assisted teleprotection instead of local step-distance protection to accelerate the operation time of Zone 2 faults from 20–40 electrical cycles down to 2–4 cycles. Transfer control commands with a typical 5.5-millisecond latency with SEL Mirrored Bits communications.

Electrical Distribution Automation/Restoration

Quickly restore distribution service and improve system availability by using SEL-3031 Radios to communicate with recloser controls and other devices.

Independent Applications Via One Radio Link

Simultaneously communicate with up to three independent ports and protocols in (P2P) operation. A typical application is to set up one port for high-speed teleprotection or control, another for SCADA, and one for engineering access.

Distributed Generation Connection

Provide low-cost communications for anti-islanding applications between the electric utility network and the distributed generation site. Designate one of the other serial channels for electric utility SCADA and one for the independent power producer SCADA.
