The UDC3500 monitors and controls temperature, pressure, flow, level and other process variables in a wide range of single loop and cascade control options. The UDC3500 features two loops of cascade/internal control with a typical accuracy of +/-10 percent. Up to five analog inputs, three analog outputs and configurable math functions enable the UDC3500 to be used in both complex process control applications and to control variables such as carbon potential and oxygen in thermal processing applications. Other features include a NEMA 4X/IP66 rated front faceplate, and an infrared communications port with accompanying software.
