About the Crestron GLR-HD-1P
The GLR-HD-1P switches a single pole and supports 120, 230, 277 and 347 V applications. Each output has a positive air gap, and the rating is 20 A and 1.5 HP per channel. The relay integrates with the GLXX-HDSW8 and GLXX-HDSW16 modules and is part of a complete, Crestron engineered GLPX Green Light Express panel.
When replacing a relay, match the pole count and voltage to the circuit. The GLR-HD-1P is the single pole relay for 120, 230, 277 and 347 V applications, while the GLR-HD-2P is the double pole relay for 120/208, 277/480 and 230/400 V 3-phase applications. Both carry the same 20 A, 1.5 HP rating per channel.

Questions about the Crestron GLR-HD-1P
What is the Crestron GLR-HD-1P?
It is a heavy duty single pole relay from the Green Light Express range. The modular relay is designed for the GLXX-HDSW8 and GLXX-HDSW16 switch modules and forms part of a complete, Crestron engineered GLPX Green Light Express panel for heavy duty loads such as motors and electronic ballasts.
Which modules does the GLR-HD-1P work with?
Crestron lists integration with the GLXX-HDSW8 and GLXX-HDSW16 modules. The GLXX-HDSW16 is a switching module chassis for up to 16 channels, and it requires GLR-HD-1P single pole or GLR-HD-2P double pole heavy duty relays.
Can the GLR-HD-1P switch motor loads?
Yes. Crestron intends it for heavy duty loads, including motors and electronic ballasts. It is rated 20 A and 1.5 HP per channel, and each output has a positive air gap.
What is the difference between the GLR-HD-1P and GLR-HD-2P?
The GLR-HD-1P switches a single pole and supports 120, 230, 277 and 347 V applications. The GLR-HD-2P switches two poles and supports 120/208, 277/480 and 230/400 V 3-phase applications. Both are rated 20 A and 1.5 HP per channel and work with the same switch modules.
How does the relay fit into a lighting panel?
The relay is part of a complete, Crestron engineered GLPX Green Light Express panel. Within the panel it integrates with a GLXX-HDSW8 or GLXX-HDSW16 heavy duty switch module; the GLXX-HDSW16 chassis provides up to 16 channels and its modular design allows relays to be added when needed.
How much is the Crestron GLR-HD-1P?
Crestron asks its dealers to give the price of the GLR-HD-1P directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.
Can 1Install supply, install and programme the GLR-HD-1P?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the GLR-HD-1P on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.
Does the GLR-HD-1P come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the GLR-HD-1P develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.
Is the GLR-HD-1P in stock?
We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.
Can I buy the GLR-HD-1P without installation?
Yes. We supply Crestron to end users, with or without installation. Like most Crestron devices of this type, it needs setting up or programming before it works in a system, and we can quote for that too.
