1/4 DIN Ramp/Soak Temperature/Process Controllers with Modular Outputs and Communications

Item# CN3251-DD

1/4 DIN Ramp/Soak Temperature/Process Controllers with Modular Outputs and Communications 1/4 DIN Ramp/Soak Temperature/Process Controllers with Modular Outputs and Communications
The CN3251 1/4 DIN temperature and process controller is a low cost, high performance single loop controller that can be used for temperature, flow, pressure and level control applications. With universal sensor inputs and front panel operator setup, one CN3251 controller can be easily field configured for a wide variety of applications, and simply reconfigured as application needs change. This makes it an exceptional choice for applications requiring multiple control needs, manufacturing facilities, testing facilities and testing applications.
