About TC
The CB Range of Dual Display Temperature and Process Controllers
Fully programmable PID or ON/OFF with adjustable hysteresis as configured by the user.
Active Tuning and Self Tuning
In addition to self tuning the CB range also features continuous active tuning. Active tuning which can be manually selected, automatically adjusts PID values as a result of a process disturbance, to ensure optimum performance.
Up to two low cost alarms may be specified and configured by the user to act as deviation or process alarms.
One alarm may be configured by the user to detect a fault in the control loop caused by failure of the heater element, load relay or sensor circuit.
In the event of a heater failure this option produces an alarm output. A matching current transducer available from TC Ltd is required for this option.
A wide range of thermocouple and resistance thermometer inputs can be specified.  Current and voltage inputs are also available.
Relay, SSR and current outputs are available for heat and heat/cool action.
RS485 communication is available (as ANSI serial code or Modbus protocol) allowing the CB range to be connected to PCs and PLCs. Up to 32 instruments can be connected to a single communication port.
Heating/Cooling Control Action
Heating/Cooling control action is available with self tuning. A choice of control signals is available for both heating and cooling outputs.
Simple Panel Mounting Feature
The CB range mounting brackets enable up to six controllers to be fitted horizontally in a single panel cut out thereby saving space and installation time.
Waterproof and Dustproof Version
An IP66 version of the CB100 and IP65 version of the CB400 and CB900 are available.
Process Value Bias  
This option allows the measured object temperature to be offset on the display to compensate for errors due to difficulties in correct placement of the sensor.
Data Security
Non volatile memory and set data lock prevents loss or inadvertent change of data due to power failure or incorrect operation.
A choice of 85/264V AC or 24V AC/DC supplies is available.
