General Description

Congratulations, you’re about to become a fully-qualified user of the Watlow

Series

920!

This versatile microprocessor-based ramping control is powerful, yet

simple to learn. A ramp progresses from one set point to another set point over a

period of time.

In this chapter of the user’s manual, you’ll get an overview of the

920 and its operation.

Figure 1 is a simplified view of the Series

920’s

capabilities. It is a dual output,

microprocessor-based, 1/

DIN-sized ramping temperature control. The 920

accepts a single, front panel-selectable input. This includes Type

K, T,

or B thermocouple input, a 1° or 0.1°

RTD

input, or one of two process inputs. It

has a full control temperature range, offset calibration, and a front panel lock-out

feature.
