R8845U Universal Switching Relay

Transcription

1 Universal Switching Relay PPLIION he Universal Switching Relay provides intermediate switching of line- and low-voltage devices from a line- or low-voltage controller. he may be used to replace several Honeywell or competitive switching relays and is typically applied in hydronic heating systems. SPEIFIIONS Electrical Ratings: Voltage: 0 Vac, 60 Hz. hermostat Heat nticipator Setting: 0.. ransformer Ratings: Primary: 0V, 60 Hz. Secondary: Vac, V maximum; 9 V available for external loads. Output protected by replaceable automotive fuse. INSLLION INSRUIONS ontact Ratings:. FL,. LR on each set of line voltage contacts; maximum connected load is 000 V. Switching ction: Spst, plus Powerpile rated low-voltage Spst. If normally closed contacts are needed, use R889 Switching Relay. Electrical onnections: No. 8 captivated wire clamp screw terminals. Dimensions: See Fig.. ross Reference: he replaces Honeywell models R8,,,J; R8,,,J; R85, R88,,,J and R8, as well as several competitive models. See able for additional cross reference information.

For new installations, locate the relay vertically on a solid wall or partition as close as possible to the device to be controlled. Select a location that is easily accessible for installation and service.

Follow all instructions furnished with the controlled equipment. Fig.. dimensions in in. (mm). INSLLION When Installing this Product.... Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition.. heck the ratings given in the instructions and on the product to make sure the product is suitable for your application.. Installer must be a trained, experienced service technician.. fter installation is complete, check out product operation as provided in these instructions. 5. Follow local codes for installation and application. WRNING Electrocution Hazard. Power supply can cause severe injury, or death. ransformer core not bonded. Disconnect power supply before wiring. IMPORN he switching relay terminals are approved only for use with copper wires. When two or more line-voltage load devices are to be controlled in parallel, the total current must not exceed the rating for the relay load outputs. Never connect load terminals to a load that uses more current than the amount listed in the electrical ratings on the relay. See able for maximum low-voltage wiring length specifications.
