Overview
LR-7P relay is a magnetic latching type relay that can be attached to 4eRM as a plug-in type.
LR-7P can be opened and closed by applying DC12V, and can be applied up to the maximum usable capacity indicated in the specifications for tungsten filament, ballast and resistive load. It has a manual OVERRIDE switch, so it can be turned ON/OFF in case of emergency.
Main Feature
Application
LR7P relay is a plug-in type relay installed in the 4eRM relay module, and there is a switch and status display for manual operation of the relay on the top, so you can check the current ON/OFF status. This relay is normally mounted on the relay module, and there is an LED status indication on the front of the relay module, and the relay itself is also equipped with a status indication by a manual switch.
Install in the 4eRM module as a Plugin method.
By selecting the two separate low-voltage coil (24V), it maintains and ON(OFF) the contact point by mechanically.
It maintains the ON/OFF status to make no change of status when black-out.
It minimizes the power consumption by charging the status of Relay when power is consumed.
The manual control is possible through the lever that placed at top of Relay.
