A350A/B Series
Electronic On/Off Temperature Control
Description Features
The A350A/B Series are On/Off temperature • field selectable heat/cool mode
controls with a SPDT relay output and LED • adjustable setpoint and differential
indication. These controls are used in • surface or DIN rail mounting
conjunction with the A99B Series (PTC silicon) • LED indication of relay status
Temperature Sensors. • 5-pin connectors eliminate wiring between
Two basic models cover a temperature range modules
of -30 to 250°F with an adjustable differential
of 1 to 30F°. A350A controls incorporate Applications
Fahrenheit scales; the A350B models have • frozen/refrigerated food cases
Celsius scales. The S350 Stage, • space temperature control
D350 Display, and Y350R Power Modules can
• cooling tower control
be used with the A350A/B.
• beverage coolers
Accessories • chiller staging
The base silicon sensor (A99BC-25C, not A350
immersible) is included with each .
A350A/B Control.
