Frequently Asked Questions - C3RY-8 Crestron

What is the Crestron C3RY-8 control card used for?

The C3RY-8 is a 3-Series control card that provides 8 normally open isolated relays for switching low-voltage loads up to 1 A at 30 V AC/DC. It is used for controlling lights, shades, screens, and other devices in a Crestron automation system.

Which Crestron control systems support the C3RY-8?

The C3RY-8 is compatible with 3-Series Control Systems such as PRO3 and AV3 (with CAGE3 expansion cage), and 3-Series Card Interfaces CEN-CI3-1 and CEN-CI3-3. It is not compatible with 2-Series systems (PRO2, AV2, PAC2).

How do I install the C3RY-8 card?

Installation requires a Phillips screwdriver and a grounding strap. Disconnect power, remove the blank faceplate, align the card in an open slot, firmly press to seat the connector, tighten thumb screws, and restore power. Ensure ESD precautions are followed.

What is the relay rating of the C3RY-8?

Each relay on the C3RY-8 is rated for 1 A at 30 V AC/DC (resistive load). Relays are normally open and isolated, suitable for low-voltage switching applications.

Can I use the C3RY-8 in a 2-Series system?

No, the C3RY-8 is not compatible with any 2-Series control system (PRO2, AV2, PAC2), even if installed in a CAGE3 expansion cage. It requires a 3-Series system.

Does the C3RY-8 require external power?

The C3RY-8 is powered directly from the control system via the expansion slot. No external power supply is needed.

How many relays does the C3RY-8 have?

The C3RY-8 provides 8 relays on two terminal blocks. Each relay is independently controllable and normally open.

What should I do if the card does not function?
