The CB Series combines easy-to-use operation with the latest temperature control advances at a competitive price. With powerful new
features such as RKC's new self-tuning for precise automatic control, digital communications for networking, IP6
6(IP65) for waterproof/dustproof
protection and heater and loop break alarm capabilities to detect system failures, these controllers deliver exceptional process performance for
the most demanding industrial applications.

IP66(65) - Waterproof/dustproof protection
The CB Series features large, bright LED displays that have
been designed to be easy-to-read from greater distances.

The Heat/Cool PID control features heat and cool outputs for
use where process-generated heat exists. This allows the input
of overlap or deadband settings which contribute to energy
savings.

The CB series offers an optional RS-485 communications
interface for networking to computers, PLCs and SCADA
software in your plant. Up to 31 units can be interfaced on one
RS-485 communication line. MODBUS protocol is also available.

Self-Tuning Algorithm
The CB Series offers a new self-tuning feature that is initiated
at start-up and when process parameters or conditions change.
In these situations, the controller evaluates whether the preset
PID parameters should be maintained or replaced by the latest
self-tuning parameters to achieve the best control for the
process. Self-tuning can be manually turned ON/OFF in the
parameter setting mode. This feature is not available with the
Heat/Cool control.
In addition to self-tuning, The CB Series has standard
autotuning (AT) so that either function can be selected to
achieve optimum process control.
