Description
The Johnson Controls C450CCN-1 is a System 450 Series control module with two SPDT line-voltage relay outputs for On/Off control. It is both a sensing control and an operating control, with a backlit LCD and four-button touchpad user interface that allows the whole control system to be set up and adjusted at the module itself - no laptop, cable or configuration software required.
System 450 is the Johnson Controls/PENN modular digital electronic control platform, designed to replace the older System 350 and System 27 ranges. Every module is multipurpose and field configurable out of the box: a single control module can work stand-alone, or plug together with expansion modules to drive up to ten outputs from as many as three control sensors, controlling temperature, pressure and humidity simultaneously if the application requires it. Modules join with plug-together connectors so no field wiring is needed between them, and the assembly mounts on DIN rail or directly to a flat, even surface. Power comes either from a C450YNN power supply module within the assembly or from an external 24 VAC Class 2 supply. Temperature sensing uses A99 PTC sensors; pressure and humidity sensors feed a 0 to 5 VDC input.
