System 450 is a family of modular, digital electronic controls that is easily assembled and set up to provide reliable temperature, pressure, and humidity control for a wide variety of HVAC/R applications, commercial process applications, and industrial process applications. The System 450 control system is designed to replace System 350 and System 27 control systems, and to provide many additional features and benefits with fewer than twenty model variations. System 450 control modules provide a field-configurable out-of-the-box solution. Most System 450 control modules can control temperature, pressure, and humidity systems simultaneously. System 450 Control Modules with Communications enable you to connect System 450 control systems to Modbus or Ethernet networks for remote monitoring and setup. The Modbus communications control module is an RS485, RTU-compliant slave device. The Ethernet communications control module has an integral web server that can deliver web pages by means of a direct connection, on your LAN, or across the Internet. System 450 Reset Control Modules provide many of the features of the standard models for temperature and humidity control. In addition, these modules provide set point reset, real-time setback scheduling, and run-time balancing (equal run time) capability. The System 450 Control Module with Hybrid Analog Output has a single self-selecting analog output to optimize and extend the controlled speed range of variable speed electronically commutated (EC) motors.
The P599 Series Electronic Pressure Transducers are compact, economical, rugged, direct-mount pressure transducers designed for use in commercial and industrial refrigeration and air conditioning applications. These transducers provide a proportional analog signal based on the sensed pressure. The P599 Series Transducers feature environmentally protected electronics with stainless steel construction. The digitally compensated P599 Transducers are highly accurate over a broad temperature range, resisting the effects of wide ambient temperature swings, high humidity, condensation, and icing. The pressure port is machined from 304L stainless steel. No O-rings or organic materials are exposed to the pressure media, allowing for a leak-proof, all-metal, sealed pressure system. The P599 Series Transducers operate with any corrosive or non-corrosive refrigerants that are compatible with stainless steel (304L SS), including water condensate, carbon dioxide, glycol, most refrigerants (including ammonia), and many other compatible fluids and gases. The P599 Transducers also can be used with the following natural refrigerants: NH3 (ammonia) and CO2 (carbon dioxide) in accordance with hazardous location requirements. The P599 Series provides transducers in a variety of pressure ranges, covering most common refrigeration and air conditioning applications. Refer to the P599 Series Electronic Pressure Transducers Product/Technical Bulletin (LIT-12012446) for important product application information.
