ATC-Automatic Timing & Control TOS Series Data Sheet

OPERATION

\\\

The 1/16 DIN TOS, is one of the most commonly used temperature con­trols because of its low cost and operation simplicity. Primarily employed
in ON/OFF output applications, the unit is also available with proportion­al control if desired.

Operation of the TOS is simple. Set the dial to the required temperature
and the control provides an output until the temperature setting is
achieved. The unit has a hysteresis of 0.2 to 0.5% of full scale to provide
fairly consistent control. Output can be ordered in either relay contact
(2A @ 250VAC, Form C) or output for solid state relay (12VDC, 20mA).
This output flexibility plus selection of J or K thermocouple input provides
a range of models to satisfy application requirements.
