s Manual

Watlow's Series 321 is a dual output, digital

countdown timer with an easy-to-use control

and display panel. The display allows you to

track remaining time and process status. On-

board memory retains the most recent time

setting for easy recall, even after power is

removed. The interlock feature interrupts

timer operation immediately when it is

opened. This feature can be used as an

interlock, remote off, or emergency shut-off.

The housing and connectors are designed for

fast and reliable installation in your product.
