Johnson Controls HE-68N3-0N00WS Penn System 450 Series Wall Mount Humidity Transmitter with Nickel Temperature Sensor: 10 to 90 +/-3% RH; 0 to 55° C

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.
