Complete Panel Systems
Temperature Control Panels are self-contained completely wired
and ready to use. Installation is simple in that only line, load
and thermocouple connections are necessary. Included is a completely
solid state temperature control such as the ETR-4120 shown or
other model. The control output signal matches the input of the
SCR or other output device. Full range temperature indication
is provided for visual monitoring. A digital process temperature
set point provides accuracy and readability.
A second thermocouple is normally included
to sense an overheat condition. A solid state high-limit control
with manual reset will shut down the circuit. Temperature and
Process Control Panels are designed based upon specific application
requirements. The following standard features can be included:
