Analog Inputs

The UDC3500 has three universal analog inputs with a typical accuracy of ±0.10% of

full-scale input and a typical resolution of 16 bits. 

These can be configured to act as one Universal and four High Level Inputs for a total of five analog inputs. 

All analog inputs are sampled six times per second (every 166 ms).

The 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 and third inputs are isolated from each other and all other inputs and outputs and accept the same actuations as input one. 

Input 3 provides the Slidewire input for Position Proportional control. These optional inputs can each be split into two high level inputs. 

The fourth input is enabled by first configuring Input 2 as a 20 mA or 5 Vdc input type (high level) and moving a jumper on the Second Optional Input Board. 

Input 4 will then be available as a high level input. 

The fifth input is enabled by first configuring Input 3 as a 20 mA or 5 Vdc input type (high level) and moving a jumper on the Third Optional Input Board. 

Input 5 will then be available as a high level input.

Features:

Powerful 32-bit processor

2 GB of memory

128 GB of storage

Supports a wide range of I/O modules

Easy to use and configure

Reliable and durable

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.

Digital Inputs

Four isolated digital inputs are provided for remote dry contact closure to select one of 25

actions. Also, two of these digital inputs can allow one of six additional selections to be

combined with one of the above selections.

Outputs

Output Types - The UDC3500 may have up to seven of the following outputs:

 Current Outputs (4-20 or 0-20 mA)

 Electromechanical Relays (5 amps)

 Solid State Relay (1 amp)

 Dual Electromechanical Relays (2 amps)

 Open Collector Output (+30 VDC @ 20 mA)

Alarms

Up to four electromechanical alarm relays are available to activate external equipment

when preset alarm setpoints are reached. Each of the four alarms can be set to monitor

two independent setpoints. Each alarm setpoint can be either high or low alarm. The

alarm type can be selected to be either of the inputs, the Process Variable, Deviation,

Output, Shed from communications, PV rate of change, or to alarm on manual mode

activation or a Current Output Open failure. It can also be used as an On or Off event at

the beginning or end of a Ramp/Soak segment. An individual alarm hysteresis setting is

provided for each relay and these are configurable from 0 to 100% of range.

 Alarms can be configured as latching or non-latching. continued

 Alarm blocking is also available which allows start-up without alarm energized

until after it first reaches the operating region.

 PV rate of change alarm.

 Loop break alarm.

 Timer output reset.

 Diagnostic Alarm

Communications

A communications link is provided between the UDC3500 and a host computer or PLC

via the RS422/485 Modbus® RTU or Ethernet TCP/IP * communications option. 

An infrared communication link is also available allowing a non-intrusive configuration of the instrument.
