LR7P
25 Ampere Latching Relay
Overview
LR-7P relay is a magnetic latching relay that can be installed in a 4eRM module.
LR-7P operates with 12V DC input and can switch tungsten lamps, ballasts, and resistive loads up to its rated capacity.
A manual OVERRIDE switch is provided for emergency ON/OFF control.
Feature
- Installed via plug-in type in 4eRM module
- Dual low-voltage (12V) coils enable mechanical ON/OFF latching
- Maintains ON/OFF state without power loss effects
- Consumes power only during switching operation
- Manual lever control available on top of relay
Operation
Application
LR7P relay is a plug-in type relay installed inside the 4eRM relay module.
It includes a manual control switch and status indicator on the top, allowing users to check ON/OFF status.
The relay is normally mounted in the module, which also provides LED status indication on the front panel and mechanical status feedback on the unit itself.
