Temperature Controller General Description 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, IP66(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. Features Bright, easy-to-read LED Displays Advanced self-tuning Digital communications Heat/Cool action Heater/Loop break alarms Bright, Easy-To-Read LED Displays The CB Series features large, bright LED displays that have been designed to be easy-to-read from greater distances. 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. Digital Communications (Optional) 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. Heat/ Cool Control (Optional) 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. Host computer

Temperature Controller CB Series Features Heater Break Alarm (HBA) (Optional)Loop Break Alarm (LBA)_(Optional) The HBA detects a fault in the heating or cooling circuit and displays actual amperage on the display on the front panel. If the measured value becomes lower than the preset value, the alarm is activated. The HBA function requires a current detector for measuring and monitoring the current load. The loop break alarm (LBA) monitors and protects an entire temperature control system. The LBA detects heater breaks, thermocouple or RTD failures, short circuits, or the failure of an operating...
