Basic Temperature and Limit Controllers Provide Economical

Solution for a Wide Range of Applications

The basic and limit microprocessor-based controllers from

Watlow® provide an economical solution for applications

requiring simple on-off control. These controllers and limits

are available in a broad range of packaging options, allowing

users to select the best version for their individual application.

The controllers and limits are available with or without an

operator interface and can be ordered in a 1/8 DIN square panel

mount, DIN-rail mount or open-board design configurations.

The basic and limit design provides significant improvements

in the performance, repeatability and accuracy offered by

analog basic temperature and limit controllers.

The variable options for the SERIES CV (controller) and

SERIES LV (limit) include an operator interface for viewing

and selecting the set point. A red, four-character, seven

segment LED displays the set point to show the process

option. The set point selection is made with a continuous

turn rotary encoder, or with discrete up/down cursor keys.

Operating range temperature values are customer definable

in the product configuration part number.

The fixed options for the SERIES CF (controller) and

SERIES LF (limit) offer fixed set points and are supplied

without an operator interface. Operating set point

temperature values are customer definable in the product

configuration part number. The SERIES TM temperature

indicator is available as an additional order option.

These basic and limit controllers are UL® recognized and

include CE approvals. The limit controllers are FM approved

with special UL® approval for the open-board potted versions.

CV and LV panel mount controllers ordered with discrete

up/down cursor keys include NEMA 4X/IP65 seal protection.

Watlow’s basic temperature and limit controllers include

industry leading service and support and are backed by a

three-year warranty.
