TC-2000 Process Controller Description
The TC-2000 Process Controller is a rugged two-stage On/Off process controller featuring data communications monitoring,
control and access with a Logix® Industrial Control System or monitoring and setpoint access with a standard PC. The unit is
housed in a water-tight Type 4X rated enclosure suitable for washdown and outdoor locations. Additional features include
independently adjustable setpoints and separate relay outputs. Each stage is configurable for operation in the Cooling or Heating
mode. High and Low temperature alarms providing a visual warning (flashing display) if the process temperature exceeds either
of the alarm setpoints. Additionally, the second relay output can be configured as an alarm output allowing direct control of an
external alarm horn or beacon. The controller comes complete with a reliable highly accurate solid-state temperature sensor
encased in a stainless-steel probe with eight feet of cable. An optional second temperature sensor is available which allows split
temperature monitoring and control. Also, a user field "scratchpad" setpoint is provided allowing computer access to field entered
information (e.g. specific gravity).
Button Functions
On/Off button - used to activate and deactivate the controller. When deactivated, the controller enters the standby
