2 UDC 6300 Process Controller Product Manual 1/03

1.1 Introduction, Continued

Inputs

Four high-level inputs are standard. They can be:

• 1 to 5 Volts,

• 4 to 20 mA, or

• 10 to 50 mA

A fifth input is available as an option and can be one of several types:

• a low-level Thermocouple or RTD sensor

• a linear input (mA, Volts, mV, or Radiamatic)

• a pulse counter input for use with frequency output devices. This Pulse

counter input can be used as a frequency input or as a setpoint adjustment

input whereby each pulse is counted as one least significant digit change

to the setpoint. A digital input selection determines the direction of

setpoint change.

Any input can be used as:

• the process variable for either loop

• remote setpoint signal

• for computing the weighted average of two inputs

• Input for Math algorithms such as feedforward Summer or Multiplier,

Input Summing with Ratio and Bias, HI/LO Input Select with Ratio and

Bias, Multiplier/Divider.

Outputs

The controller has a current output and is available with an optional

second current output for control, or a signal representing any of several

controller parameters for control or recording purposes.

Output Algorithms

Depending on how many loops you configure, the UDC6300 is available

with various preselected output algorithms including:

• On/Off,

• On/Off Duplex,

• Time Proportional Simplex or Duplex,

• Current Proportional Simplex or Duplex,

• Current/Time Duplex.

Digital Inputs /

Outputs

Four points, each of which can be an open-collector type Digital Output

for alarm and control, or a Digital Input. There are also two dedicated

Digital Inputs.
