A350E Series: Temperature Modular Control

Systems 350 Modular Temperature Control System: A350E Series

Description

The A350E is an on/off electronic cooling only control with SPDT relay output and LED indication. Besides being a cooling only control, the A350E has two features that differentiate it from the A350A/B Electronic Temperature Control: an adjustable minimum setpoint and short/open circuit protection.
The A350E also has an adjustable differential and an interchangeable temperature sensor. The A350E will accept up to nine S350 Temperature Stage Modules to control a total of ten stages of cooling.
Like all System 350 products, the A350E is housed in a NEMA 1, high-impact plastic enclosure. The modular design provides easy, lug-together connections for quick installation and future expandability.

Features 
  • Minimum setpoint selection allows greater control over the cooling system
  • Short circuit and open circuit protection safeguard the equipment by de-energizing the relay and shutting off the equipment if the sensor or sensor wiring fails shorted or open
  • Wide adjustable differential of 1 to 30F° (0.5 to 17C°) enables the user to match equipment cycle rate and/or sequencing for a given application
  • Modular design provides the flexibility to add up to nine S350 Stage Modules, a D350 Temperature Display Module, and a Y350R Power Module
  • Plug-together connectors and 35 mm DIN rail mounting eliminate wiring between modules, reducing installation costs and wiring errors
  • One dual-scale model covers a temperature range of 10 to 65°F (-12 to 18°C)
  • Interchangeable temperature sensors increase versatility and serviceability


Applications

  • Frozen/refrigerated food cases
  • Space Temperature control
  • Cooling Tower Control (cooling only)
  • Beverage Coolers
  • Chiller Staging


Accessories

  • A99BC-25C  (included with each A350E Control)
