System 350™ MODULAR TEMPERATURE CONTROL SYSTEM

A flexible, expandable and economical system of modular controls which allows cus- tom tailoring to any of a wide range of refrigeration, commercial HVAC and process temperature control requirements. The basis for the system is the temperature control module. Add-on modules for staging, LED display and 24 volt power are easily added to meet the needs of the specific application. The modules are commonly mounted on a rail, and snap together with built-in plugs so that there is no interconnecting wiring. Electrical; ratings: 9.8 amps @ 120v, 4.9 amps @ 240v.

TEMPERATURE CONTROL A350 Series

MODULAR

Automatic reset electronic SPDT temperature control can be used independently or with any of the plug-in accessory modules to make up a wide variety of single or multiple stage refrigeration or HVAC control systems. Designed with heat/cool switch, adjustable differential, LED operation indicator and interchangeable temperature sensors.

S350 Series STAGING MODULE

Receives power, set point and sensor input from A350 temperature control. Up to 5 stage modules can be added to the basic System 350™. Designed with heat/cool switch, adjustable differential and

adjustable offset (amount of offset from A350 setpoint determines point at which S350 relay energizes).

D350 Series DISPLAY MODULE

Receives power, sensor and setpoint information from A350 control, continuously displays sensor temperature with 3-digit LCD.

Momentary push button switches display to show setpoint. Can be mounted on rail with System 350™ or remotely with optional cable.
