Auto-Tuning PID Controllers

Advantages of IDC include automated logging of key process variables, increased accuracy and ease of use for recipe or con­figuration setups. Infrared data communications enhances controller data exchange in physically restricting environments (such as semiconductor clean rooms, governmental radio-active test labs or those hard to reach areas) and reduces the use of paper to record instrument information as well as human transposition errors.

• Process output (Non Isolated) User-selectable 0-10V=(dc), 0-5V^(dc), 1-5V=(dc) @

1KQ minimum, 0-20mA, 4-20mA @ 8000 maximum

• Electromechanical relay. Form C, rated 5A @ 120V~(ac),

5A @ 240V~(ac) or 5A @ 30V^(dc)

• Open collector 42V^(dc) @ 250mA maximum

• EIA-485 serial communications with Modbus™ protocol

• 9600, 19.2K or 38.4K baud rates

The Infrared Data Communications (IDC) option is available on all SERIES SD controller models except the /32 DIN and can support complete SERIES SD parameter configuration and operation. The IDC option supports wireless communications with PDAs (personal digital assistants) or other devices equipped with infrared communications that support the Infrared Data Association (IrDA) 1.0 Standard.

The actual user interface or configuration is dependent on the master device application software. A source for this software is Instant HMI from Software Horizons, For more information, visit www.instanthmi.com/watlow,

WATVIEW, Watlow's Windows® based HMI (Human Machine Inter­face) software, supports the SERIES SD controllers. The software can be used to setup, monitor and edit the values of controller parameters, to monitor and manage alarms and to log and graph process data.
