Honeywell UDC1200&UDC1700 Universal Digital Controller Series

Honeywell UDC1200&UDC1700 Universal Digital Controller Series

Overview

UDC1200 and UDC1700 are 1/16 DIN and 1/8 DIN controllers, respectively, based on microprocessors, with high functionality, reliability, and low cost. They are dedicated to monitoring and controlling temperature, pressure, and liquid level, and are widely used in environmental testing chambers, furnaces, ovens, packaging machines, as well as industries such as plastics, food, and beverages. It is equipped with large and easy to read dual 4-digit displays and tactile buttons, making it convenient to configure and use. It has high flexibility and can be configured for different applications, and is compatible with UDC1000/1500 downwards.

Characteristics

Dual Display Screen: Two 4-digit 7-segment LED displays, configurable to display PV and SP (non adjustable), PV and SP (adjustable), PV and slope SP, PV only, and other content.

Easy to configure: Two configuration levels (configuration mode and setup mode) facilitate access to parameters, and a 4-digit security code prevents unauthorized changes.

Moisture resistant front: Complies with NEMA 3/IP65 front protection standards and is dustproof and waterproof.

Universal input: can accept seven different types of thermocouples RTD、 Linear input of current and voltage, all inputs can be configured as standard.

Universal power supply: can operate at any line voltage from 90 Vac to 264 Vac, 50/60 Hz, and also offers 24/48 Vac/dc model options.

Easy upgrade: All option boards do not require jumpers, and the instrument can automatically detect them.

Convenient output selection: All outputs of the instrument (including control outputs) can be changed to meet the exact needs of customers.

Alarm strategy: Two soft alarms for PV, including deviation high/low/absolute alarms, as well as special circuit alarms that can suppress alarms during power start-up and setpoint switching.

Manual/Automatic Mode: Manual control (disturbance free switching) can be enabled through the front AUTO/MAN button.

Pre tuning and self-tuning strategies: Pre tuning is used to set PID parameters close to optimal values, while self-tuning algorithms are subsequently used to optimize tuning parameters.

Limit Controller: The UDC1200 limit controller is packaged in 1/16 DIN and designed to provide safe shutdown and optional alarms.

Up to three outputs: can provide up to three outputs for time and current ratio, duplex mode (heating/cooling), PV or SP retransmission, and alarm.

Setpoint Slope: The current setpoint can be sloped to a new target setpoint at a user-defined slope rate.

Dual Setpoints: UDC1200 and UDC1700 offer dual setpoint options, selecting the current setpoint through numerical input.

Communication function: RS485 communication interface is optional, which can connect up to 32 units and one host at up to 19200 baud rate through ASCII or Modbus RTU protocol.

High security: Non volatile memory based on EEPROM technology ensures data integrity in the event of power failure, with a retention time of over 100 years, and a 4-digit security code to prevent unauthorized or accidental changes.

Optional Features

RS485 ASCII communication, RS485 Modbus RTU communication, digital input, output 2, output 3, 24/48 Vac/dc power supply and other functions can be selected through the model selection guide.

Physical description

UDC1200: The shell depth is 110 mm (4.33 inches), with a standard UDC gray border, and can be installed at 1/16 DIN panel cutouts.

UDC1700: The shell depth is 100 mm (3.94 inches) and can be installed at the 1/8 DIN panel cut. It can be easily and safely installed to the panel cut using the accompanying pre assembled installation fixture. The modular plug-in structure is easy to access, and all inputs and outputs are connected to the rear terminal block by screws.

Operator interface

Provide four display combinations, the upper 4-digit 7-segment display is always used to monitor PV, and the lower display can display set points (read-only), set points (adjustable), slope set points (slope mode), blank, and other content. There is an AUTO/MAN button on the front (to select manual or automatic mode, which changes to "reset" on UDC1200 limit models)
