The PTC-1A timer is a low-power, LCD control product
designed to combine a harmonized appearance with
simple-to-operate, flexible functions and highreliability. It is ideal for frequent user-adjustable
applications such as hot foil printing, window sealing,
and environmental ovens, which often require both
temperature and timing control.
The use of the PTC-SW momentary switch, included
with the PTC-1A, allows cycle reset from a remote
location for the PTC-1A. The switch has tamper-proof
range and mode settings for added security.

bracket (included).
