Watlow’s SERIES 96 is a powerful 1⁄16 DIN dual display
controller that offers many advanced functions. This new
controller can be tailored to perform hardware and software
needs with hardware modules that are pluggable and
exchangeable and software menus that may be user
programmed to fit exact application requirements.

With one universal input, a second auxiliary input and four
outputs the SERIES 96 can be programmed to perform:
temperature measurement, input event switching, remote
set point input, heating, boost heating, cooling, alarms,
digital communications, ramp and soak and retransmit.
These features make this controller ideally suited for
applications in markets such as plastics packaging,
semiconductor, food processing and lab equipment.

Set point ramping operations include two files with eight
steps in each. The files can be linked to create a 16-step
profile.

With fast 10Hz sampling, variable time base burst firing
outputs, NEMA 4X front panel and 0.1 percent calibration
accuracy this control can easily handle some of the
toughest application needs.

The SERIES 96 is manufactured by ISO 9001 registered
Watlow Controls and reliably backed by a three-year
warranty.
