SEL-2516

Rack-Mount Remote I/O Module

The SEL-2516 is a rack-mount remote I/O module designed to add digital input and output capabilities to SEL communications processors. This device enhances SCADA functions and improves engineering access, allowing for more reliable and cost-effective system integration compared to using traditional Remote Terminal Units (RTUs).

Key Features

Digital I/O Expansion

Provides eight status-sensing inputs to monitor external contacts and eight contact outputs for executing control commands.
Enhanced Safety

Replaces control wiring to outside cabinets with fiber-optic cables to eliminate paths for dangerous voltages and protect personnel.
Increased Dependability

Utilizes fiber-optic links to prevent data errors caused by electromagnetic interference (EMI). The communications processor monitors the link status and triggers an alarm if communications are interrupted.
Integrated Operating Environment

Integrates with SEL communications processors and protective relays to provide SCADA functions, power system report management, and high-speed local logic without the need for additional equipment.
Rugged Environmental Durability

Supports a wide operating temperature range from -40°C ~ +85°C for stable performance in extreme industrial environments.

Standard Rack-Mount Design

Designed to be installed in a standard 19-inch rack (2U height), ensuring easy integration into existing panels and systems.
Screw-Terminal Connectorized (STC) Blocks

Features patented STC blocks that allow for the rapid installation and removal of the module without disturbing the individual wiring during maintenance.
Customizable LED Labels

Users can print configurable labels for the LEDs to clearly identify and display the status of all I/O points.
Back-Panel Switches

Allows for the easy setup of operating parameters on-site using switches on the back panel without complex software procedures.
Intuitive Status Indication

Features front-panel LED indicators to provide real-time status for all I/O points and includes a Lamp Test function to easily verify LED operation.
