The UDC3200 universal digital controller packs powerful features in the popular 1/4 DIN size.
Unmatched application power includes: infrared (IR) configuration interface, two universal analog inputs and a math algorithm. When these are combined with the Accutune III ™ tuning with fuzzy logic overshoot suppression, the result is price/performance leadership.
Application flexibility is assured by the universal analog inputs, universal AC power supply, two digital inputs, a maximum of five analog and digital outputs, RS422/485 Modbus RTU or Ethernet 10Base-T TCP/IP communication protocols, simple configuration plus total field upgrade capability for any optional feature.
The UDC3200 has two analog inputs with a typical accuracy of ±0.20% of full-scale input and a typical resolution of 16 bits. Both analog inputs are sampled six times per second (every 166 ms).
The first, or process variable input, can be one of the various thermocouple, RTD, Radiamatic or linear actuations. Linear actuations have thermocouple, RTD, and Radiamatic transmitter characterization capability as a standard feature. Linear actuations also have square root capability.
The optional second input is isolated and accepts the same actuations as input one, or it provides the slidewire input for position proportional control.
All actuations and characterizations are keyboard configurable. Cold junction compensation is provided for thermocouple type inputs. Upscale, downscale or failsafe sensor break protection is keyboard configurable. A configurable digital filter of 0 to 120 seconds provides input signal damping.
A pre-configured algorithm is available for easy implementation. This includes the capability of using a ratio and bias with any input. You can select from the following menu:
