HoneywellUDC1200 & UDC1700 Universal Digital Controllers Series Micro-Pro Specifications 51-52-03-35 June 2011

Overview 

The UDC1200 & UDC1700 are microprocessor-based 

1/16 DIN and 1/8 DIN controllers, which combine a 

high degree of functionality and reliability at low cost. 

They are fully dedicated to monitor and control 

temperatures, pressures and levels in a wide range of 

applications such as environmental chambers, 

furnaces, ovens, packaging machines and other 

applications in plastics and the food and beverage 

industries. The large and easy-to-read dual 4-digit 

display and tactile keypad make the UDC1200 and 

UDC1700 easy to configure and use. Their 

outstanding flexibility enables you to configure any unit 

for any application and change it if required. 

For the thousands of satisfied UDC1000/1500 users, 

the UDC1200/ 1700 controllers are downward 

compatible to existing UDC1000/1500 applications 

and installations. 

Features 

Dual display 

Two 4-digit displays with 7 LED segments, each 

configurable for: 

 PV and SP (non adjustable) 

 PV and SP (adjustable) 

 PV and Ramping SP 

 PV only 

Easier to configure 

Two different configuration levels (Configuration mode 

and set-up mode) provide easy access to parameters. 

A 4-digit security code prevents unauthorized changes. 

Moisture resistant front-face 

Meets NEMA 3 / IP65 front-face protection against 

dust and water. 

Universal input 

Accept seven different types of thermocouples, RTDs, 

current and voltage linear inputs. All inputs are configurable 

as standard. 

Universal power supply 

The UDC1200 and UDC1700 can operate on any line 

voltage from 90 Vac to 264 Vac at 50/60 Hz. A 24/48 Vac/dc 

model is available as an option. 

Easy upgrade 

All the option boards are jumper free and detected 

automatically by the instrument. 

Easy output selection 

All the outputs (including the control output) of the 

instrument can be changed to meet the exact 

customer’s needs. 

Alarm strategy 

Two soft alarms for PV, deviation high/low/absolute. A 

special loop alarm is also provided to detect faults in 

the control loop by continuously analyzing the PV 

response to the control output. Alarm inhibit is 

available on power up and setpoint switching. 

Manual/Automatic mode 

Manual control (via bumpless transfer) is enabled by 

simply pressing the front-face AUTO/MAN key. The 

“SET” LED flashes and the output power is displayed 

on the lower display. Output can be adjusted with the 

upper and lower keys. 

Pre-tuning and self-tuning strategy 

Pre-tuning is used to set up the PID parameters close 

to the optimum values, which the self-tuning algorithm 

uses to subsequently optimize the tuning parameters. 

Limit controller 

Packaged in 1/16 DIN, the UDC1200 limit controller is 

designed to provide a safety shut-off and optional 

alarm for use in a wide variety of applications. 

Up to three outputs 

The UDC1200 and UDC1700 provide up to three 

outputs for time and current proportioning, duplex 

mode (heat/cool), PV or SP retransmission, and 

alarms. 

Setpoint ramp 

The current setpoint can ramp to a new-targeted 

setpoint by way of a user defined ramp rate. 

Dual setpoint 

Dual setpoint option is available on the UDC1200 and 

UDC1700. The current setpoint is selected by a digital 

input. This option is exclusive with UDC1200 limit 

model remote alarm reset. 

Communication 

An optional RS485 communications interface is 

available on the UDC1200 and UDC1700. It provides a 

link for up to 32 units and a host computer through 

ASCII or Modbus RTU protocol at up to 19200 baud. 

Highly secure 

A non-volatile memory based on EEPROM technology 

ensures data integrity during loss of power supply, with 

retention of more than 100 years. A 4-digit security code 

prevents unauthorized or accidental change. 

UDC1700 UDC1200 

Upper display: 4 characters 

dedicated to show the PV. 

In configuration mode, it shows 

the parameter value or selection 

Lower display: 4 characters 

dedicated in normal operation 

mode to display the SP. In 

configuration mode, it displays 

the parameter name.

Selects manual or automatic mode. Becomes 

« Reset » on UDC1200 Limit model. 

Allows operator mode parameters to be scrolled. 

In combination with the «Upper» key, allows 

configuration mode or Setup mode to be entered. 

Increases setpoint, output or configuration 

parameter values. 

Decreases setpoint, output or configuration 

parameter values.

Optional Features 

The following can be selected via the Model selection 

Guide (see page 8):

 RS485 ASCII communication 

 RS485 Modbus RTU communication 

 Digital Input 

 Output 2 

 Output 3 

 Power Supply 24/48 Vac/dc 

Physical Description
