Multipurpose, All-in-One Control Modules Enable simple stand-alone, single-module control systems that are temperature, pressure, and humidity capable out of the box and easy to set up in the field to replace a wide variety of OEM HVAC/R and process controls. An Extensive Suite of Compatible Temperature and Humidity Sensors and Pressure Transducers Allows you to monitor and control a wide range of HVACR and process conditions in a variety of standard and global units of measurement. High Input Signal Selection Enables your control system to monitor a temperature, pressure, or humidity condition with two or three sensors (of the same type) and control your system outputs based on the highest condition value sensed by the referenced sensors. Differential Control Enables your control system to monitor and maintain a temperature, pressure, or humidity differential between two sensor points within a system, process, or space. Selection chart Refer to the System 450 Compatible Sensors, Transducers, and Accessories Catalog Page (LIT-1900662) for temperature sensors, humidity sensors, and pressure transducers compatible with the System 450 Control Modules with Analog Outputs. Table 332: Standard System 450 Modules and Accessories Ordering Information Product Code Number Product Description C450CPN-4C Standard Control Module with LCD, Four- Button Touchpad UI, and Analog Output; provides one analog output (0 to 10 VDC or 4 to 20 mA self-selecting signal) for proportional control. C450CQN-4C Standard Control Module with LCD and Four- Button Touchpad UI, and Analog Output; provides two analog outputs (0 to 10 VDC or 4 to 20 mA self-selecting signals) for proportional control.
