Johnson controls A350AA-1C electronic temp. control
A350AA-1 (C) ELECTRONIC TEMPERATURE CONTROL
A350AA-1C TEMPERATUR RANGE -30/130F, 24 VOLT, SPDT SWITCHING (SINGLE POLE DOUBLE THROW)
Control Sensor Included Sensor lead length is 9-3/4 in. (0.25 m):
A99BB-25C; Range: -40 to 212°F (-40 to 100°C)
The A350A/B Series is an on/off electronic temperature control with a Single-Pole, Double-Throw (SPDT) relay output and a Light-Emitting Diode (LED) relay status indicator. Designed to operate with both heating and cooling equipment, this control includes an adjustable differential and an interchangeable temperature sensor.
As are all System 350â„¢ products, the A350A/B is housed in a NEMA 1, high-impact plastic enclosure. The modular design provides easy, plug-together connections for quick installation and future expandability.
Modular Design Enables stage, display, and power modules to be purchased and installed as needed
Plug-together Connectors and 35 mm DIN Rail Mounting Eliminates wiring between modules and reduces installation costs
Two Standard Models Cover Wide Setpoint Ranges -30 to 130°F (-34 to 55°C) or 90 to 250°F (32 to 121°C) Reduces inventory by encompassing temperature ranges required to support the majority of Heating, Ventilation, Air Conditioning, and Refrigeration (HVAC/R) applications
Wide Adjustable Differential of 1 to 30F° (0.6 to 16.7C°) Enables the user to match equipment cycle rate and/or sequencing for a given application
Field-Selectable Mode Jumpers Operates in both heating and cooling applications
Available with Either External or Concealed Setpoint Helps deter accidental and unauthorized adjustments
Interchangeable Temperature Sensors Increases versatility and serviceability
