Honeywell UDC1200 & UDC1700 Universal Digital Controllers Series Micro-Pro Agent

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.
