Analog Inputs

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.

Thermocouple Health – In addition to the standard configurable upscale, downscale

or failsafe output burnout selections, the condition of the thermocouple can be

monitored to determine if it is good, failing or in danger of imminent failure.
