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.
