Series SD Temperature Controllers
Economical with the Latest Advanced Features
The Watlow SERIES SD family of PID temperature controllers utilizes today's advanced technology to provide the value, benefits and accuracy you've come to expect from Watlow. The features and performance offered by SERIES SD controllers make them ideally suited for a broad range of applications in temperature and process control.

The SERIES SD single channel controllers include a universal sensor input with up to three outputs that can be programmed for heat or cool temperature control, or to operate as process or deviation alarms. Programming inverse scaling is also simplified with the user-friendly set-up menu, providing additional value without additional cost.

Advanced features of SERIES SD controllers include EIA 485 ModbusTM serial communications, Watlow's INFOSENSE sensor technology, infrared remote communications operation, Watlow's patented User Definable Menu System and a "Save and Restore" feature that allows the restoration of either factory or user-defined settings. Available in 1/32, 1/16, 1/8 and 1/4, DIN panel mount sizes.

Watlow's SERIES SD family is backed by an industry leading three-year warranty from Watlow Winona. The SERIES SD controllers are UL and C-UL listed, CSA and CE certified and include the NEMA 4X (IP65) seal. The controllers are also available in FM limit approved versions.

WATLOW SERIES SD31Controllers

The Watlow Series SD31 Control offers many of the same features as the standard Series SD control in a smaller more economical package. The SD31 is a 1/32 DIN control with a single display. The SD31 offers improved accuracy of 0.1 percent of span as well as a faster sampling rate of 6.5Hz. An optional full featured countdown timer operates in a choice of delay-on, delay-off, signal-on or signal-off modes. This timer supports set point tracking during countdown for both heat and cool process variables. With optional EIA-485 communications,you can configure, monitor and data log with such optional software products like WATVIEW.

WATLOW SERIES SD Limit Controllers

The WATLOW SERIES SD family of limit controllers has been designed with the same microprocessor-based technology as the SERIES SD PID family of temperature controllers. The limits come with the FM (Factory Mutual) agency approval - the industry's most recognized designation for insurance concerns.

Limit controllers are typically added to thermal applications to monitor an over-temperature condition as a safety precaution. Limit controllers provide a redundant safety assurance to guard against instances where a high temperature runaway condition could result from a shorted input sensor, or from an output device that fails in a closed position.

Limits are recommended and are often required in applications where thermal runaway could result in costly operator safety concerns, product scrap, damage to capital equipment or a fire hazard.

Infrared Communications

The Infrared Data Communications (IDC) option is available on all SERIES SD controller models except the 1/32 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.

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.
