CB Series

The CB Series combines leading edge temperature control developments with easy-to-use operation in a cost-competitive package. These versatile controllers can be configured for the most demanding applications. With powerful new features such as Active-tuning, digital communications, user-friendly functions, large, bright displays, IP66, and advanced heater and loop break alarm capabilities, these controllers deliver exceptional temperature performance to your process for the new Millenium.

Active-tuning takes control to a new dimension!
Active-tuning (Self-tuning) is initiated at start-up and when process parameters or conditions change. The CB Series monitors your process and automatically sets new PID parameters when needed. Active-tuning can be manually set on or off. The CB Series offers both Active-tuning and our RKC world-renowned auto-tuning algorithm. * Active-tuning function is not available with heat/cool PID control type.

Digital Communications
The CB Series offers an optional RS-485 communications interface for networking to computers, PLCs and SCADA software for your plant. Up to 31 units can be interlaced on one RS-485 communication line.

RUN/STOP Mode
To toggle between modes, press the RUN/STOP key for one second. The instrument monitors the process value even when in STOP mode.

Close Horizontal Spacing
The mounting bracket has been redesigned to allow closer placement between instruments to save valuable panel space.

Heat/Cool Control
The use of Heat/Cool PID control contributes to energy savings in applications where process-generated heat exists. The controller allows the input of overlap or deadband settings

Loop Break Alarm (LBA)
The LBA monitors and protects an entire temperature control loop. The LBA detects a heater break, an incorrect sensor placement, a sensor break or the failure of output device such as SCR's and SSR's.

Dustproof and Waterproof Protection
For operation in severe environments or when washdown is required, IP66(65) is available.

Temperature Alarms
The CB Series provides a wide selection of alarm types to configure up to two alarm contacts. Alarm Hold action is configured in the controller. Upon start-up, alarm action is suppressed by the Hold function until the process value has entered the non-alarm range.

Heater Break Alarm (HBA)
The HBA detects a fault in the heating or cooling circuit and displays actual amperage on the front of the controller. The HBA monitors the load current of a heater by using a dedicated current transformer (CTL-6-P-N: 0 to 30A, CTL-12-S56-10L-N: 0 to 100A). When the control output is ON and the load current drops below a specified minimum (it is likely that a heater break has occurred), an alarm is turned on. When the control ouput is OFF and the load current is still present (indicating a short circuit in the relays of SSR's etc), the alarm is also turned on.
