GR 2400 Relay Panel
The GR 2400 Relay Panel is a 100% digital solution for lighting control, designed for centralized panel applications. It is part of the expansive GR 2400 system and can connect up to 127 addresses of digital devices, including other LC&D panels and switches. Devices daisy-chain together using Cat. 5 patch cables with RJ45 connectors.
Features
- Astronomical time clock with 32-channels and a large display (21 x 8 characters) for system programming. Non-volatile memory retains all programming indefinitely.
- 10-year battery back-up for time-of-day functions.
- Supports mixed voltage (120V, 277V) for power controllability.
- Manual override capability for the entire panel, individual relays, and zones.
