Relay packs SC2300E5045 are used in conjunction with the 8000 and 7000 series SER8300 and SER7300 Room Controllers for Low Voltage Fan Coil Unit applications. The relay packs are specifically used for other applications such as Motor, Compressor or mixed voltage fan coil control. The relays rated supply voltage is between 220 and 240V AC 1 Phase at 50 or 60Hz. The rated power is 12VA at 0.5A, 0.25hp at 2.5A The pack has 3 digital inputs for fan speed. It has 3 outputs for fan relays and 2 outputs for power supply output. The output voltage is 24V AC for control circuit. The relay pack has a NEMA 2 degree of protection. The ambient air temperature for operation is between 32 and 122 oF. The ambient air temperature for storage is between -22 and 122 oF. The relative humidity for operating or storage is between 5 and 95% non condensing.
