描述

The UDC 2800 is the next generation of panel-based temperature controller. It’s more connected, more accurate, faster and more efficient, delivering improved performance and a lower cost of ownership. With Bluetooth and remote connectivity, app-based configuration and a full-color TFT screen it’s an easy to use, powerful solution for single loop control of furnaces, ovens, boilers, heaters, environmental chambers, cookers, dryers and freezers.

The UDC2800 delivers 0.15% accuracy and a market-leading scanning speed of 100ms to capture trends quickly and enable users to achieve their targeted temperature profile. It supports up to 64 setpoints segment and four PID sets, with RTD, TC, mV, mA, RH, carbon and oxygen inputs as standard, as well as two universal analogue inputs.
UDC2800 can meet the needs of even the most complex operations. The controller is ASM2750F aerospace standard compliant as well as NEMA4X for food and beverage wash downs. FM standard for high limit heat treatment feature coming soon in 2021 and it’s also IP66 certified. ​
The controller is a single solution upgrade from both UDC2500 and UDC3200 controllers with a single solution for simpler maintenance, stock management and orders. It’s also entirely backwards compatible, retaining the same 1/4 DIN form factor, terminal arrangement and back panel as previous models.

The UDC2800 is a single solution for efficient and accurate temperature control to meet regulatory requirements, optimize performance, ensure product quality and minimize waste.

Analog Inputs

UDC2800 has two analog inputs with a typical accuracy of ±0.15% of full-scale input and a typical resolution of 16 bits. Both analog inputs are sampled ten times per second (every 100 ms)

The first, or Process Variable input, can be one of the various thermocouple, RTD or linear actuations. Linear actuations have thermocouple and RTD 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.
Math Function

Algorithm—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:
Feedforward Summer—Uses either input, followed by a Ratio/Bias calculation, summed directly with the computed PID output value to provide a resultant output to the final control element (standard feature).
Weighted Average —Computes the weighted average of a PV or SP for the control algorithm from two inputs (standard feature).
Feedforward Multiplier—Uses any input, multiplied by the calculated PID output to provide a resultant output which is sent to the final control element (standard feature).
Summer/Subtractor—Will add or subtract inputs with the result used as the derived PV.
Multiplier/Divider—Uses the analog inputs to calculate a derived PV. Available with or without Square Root.
Input High/Low Select—Specifies the PV input as the higher or lower of the two inputs.
Digital Inputs

Two isolated digital inputs are provided for remote dry contact closure to select one of the following actions.
Manual control mode
Local setpoint 1, 2, 3, 4

Outputs

Output Types – UDC2800 may have up to four outputs made up of the
following output types:
Current Outputs (4-20 or 0-20 mA)
Electromechanical Relays (5 amps)
Dual Electromechanical Relays (2 amps)
Open Collector Outputs (Transmitter Power)
Alarms

One or two electromechanical alarm relays are available to activate external equipment when preset alarm setpoints are reached. Each of the two 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. The alarm hysteresis is configurable from 0 to 100% of range.
Alarms can be configured as latching or non-latching.
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 UDC2800 and a host computer or PLC via the RS485 Modbus® RTU (optional) or Ethernet
TCP/IP (optional) communications option. A Bluetooth communication link is also available allowing a non-intrusive configuration of the instrument
