Emerson Alco 097793 Pressure Control

The Emerson Alco 097793, also identified as the PSC-W6S Pressure Switch, is a commercial-grade mini high pressure control engineered for precision sensing in refrigeration and air conditioning systems. This unit features a versatile SPDT switch configuration, allowing for seamless integration of both safety cut-out and auxiliary alarm circuits. Designed with a robust stainless steel bellows and a built-in pressure pulsation snubber, the 097793 excels in direct compressor head mounting where mechanical vibration and discharge pulses are present. The 145-623 PSI range makes it a reliable head pressure control for high pressure limit applications and condenser fan cycling. The auto reset function ensures system continuity once pressures return to safe operating levels. Installation is streamlined via the 1/4" flare with valve depressor and a DIN plug with 36" cable, providing a secure electrical and mechanical interface for the PSC-W6S in demanding environments.

• High Pressure Protection: Safeguards compressors by providing a reliable high-pressure cut-out within the 145-623 PSIG range.
• Versatile SPDT Switching: Single Pole Double Throw action enables simultaneous system shutdown and remote alarm notification.
• Durable Construction: Engineered with stainless steel sensing elements to withstand high-temperature discharge gas and mechanical stress.
• Simplified Service: Includes a 1/4" female flare with a valve depressor for direct mounting without requiring additional Schrader tools.
• Flexible Connectivity: Outfitted with a DIN plug and 3-foot cable for quick electrical termination in tight mechanical spaces.

Is the Emerson 097793 compatible with all refrigerants?
This high pressure control is designed for use with common HFC, HCFC, and CFC refrigerants found in commercial HVACR systems. Always verify chemical compatibility with stainless steel bellows if using specialized or flammable refrigerants.

Can I use the PSC-W6S for fan cycling?
Yes, the Emerson PSC-W6S is frequently utilized for condenser fan cycling to maintain head pressure in low ambient conditions, thanks to its adjustable range and SPDT configuration.

What is the difference between 097793 and PSC-W6S?
There is no functional difference; 097793 is the specific Part Code Number (PCN) for the PSC-W6S model configuration with the DIN plug and 36" cable.
