RLO-10 Relay Output Module

For the Boltek LD-250 Lightning Detector

Description

The RLO-10 is an optional relay output module for the Boltek LD-250 Lightning Detector. The
RLO-10 provides a means for connecting customer supplied equipment to the LD-250's Close
Storm Alarm, Severe Storm Alarm, and Strike indicator. Each of the three relay outputs is a
normally open solid-state contact which closes whenever the respective alarm is activated, as
indicated by the LD-250's front panel LED's. The RLO-10 uses solid-state relays capable of
switching up to 50VDC or 35VAC at up to 1.5 Amps.

Installation

Remove the top cover of the LD-250 by removing
the four cover screws. Locate the relay connector at
the front of the unit near the red alarm indicators.
