Johnson Controls S350AA-1C

STAGE ADDER MODULE; TEMPERATURE STAGE MODULE SPDT; DIFF. 1 TO 30 F; OFFSET 1 TO 30 F

The S350A Stage Module is intended to be used with System 350? controls. This stage module plugs into the respective control module to add multiple-stage capability. This stage modules has a Single-Pole, Double-Throw (SPDT) relay output with Light-Emitting Diode (LED) indication.

As are all System 350 products, the stage modules are housed in NEMA 1, high-impact thermoplastic enclosures. The modular design provides easy, plug-together connections for quick installation and future expandability.

Features:

• Modular Design - Permits system to be configured to equipment, with convenient, future expansion made easy
• Plug-together Connectors and 35 mm DIN Rail Mounting - Eliminates wiring between modules and reduces installation costs
• Selectable Mode of Operation - Provides independent relay energization, either above or below setpoint, for cooling/heating (S350A), dehumidification/humidification (S351A), or direct acting/reverse acting (S352A)
• Adjustable Differential Enables user to match the range of temperature, humidity, or pressure stage modules to specific application requirements
• Adjustable Offset Allows multiple stage sequencing of 1-30F° (0.5-17C°) (S350A), 2-30% RH (S351A), or 2-50 psi (S352AA-2)
