RLH Product Launch

Announcing the New 4 Channel Contact Closure Fiber Link System

RLH is pleased to announce our industrial 4 Channel Contact Closure Fiber Link System with SFP optics. The system provides transmission of four (4) independent digital inputs over fiber optic cable and is ideal for alarm-event triggering, building automation, environmental control systems, fire & alarm systems, gate control, traffic signal control equipment.

It is available with 24-48VDC, 12VDC or 125VDC powering options to provide installation convenience and flexibility. We offer two input types, Wet and Dry. Our Dry Contact model will provide the current to sense a dry contact closure and our wet input models will sense a provided DC voltage signal.

Each unit features a wide operating temperature, redundant power terminals, and a system alarm contact for monitoring the unit for proper operation, while LED indicators provide a convenient view of the systems current status.

This flexible, hardened system can be wall or DIN rail mounted, is made in the USA, and backed by our Limited Lifetime Warranty.
