Digital Temperature Controller CENTURY Series REX-C100 REX-C400 REX-C410 REX-C700 REX-C900 General Description The Century Series controllers are designed for precise control performance at the most reasonable cost. Available in five DIN sizes, these instruments are recognized for their solid reliability and ease-of-use. This Series features dual displays, autotuning, PID algorithm, field-selectable °C/°F, reverse or direct action and a full range of temperature alarms. Features Heat/Cool Control Standard autotuning Heater and loop break alarm Numerous control outputs Field-configurable thermocouples Loop Break Alarm The control 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 device such as a mechanical or solid state relay. 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. (Not available on REX-C100) When the PID computed value reaches 100% and the temperature does not respond in a set time, the loop break alarm is activated. Conversely, when the PID value reaches 0% and the temperature does not respond accordingly, the loop break alarm is turned on. In this example, the LBA uses reverse action to control heat. For cool control, the LBA action is reversed and becomes direct. LBA deadband is available to suppress the influence of external disturbances. Heater Break Alarm Standard Features Heat/Cool Control The heater break alarm (HBA) detects a fault in heating or cooling circuit and displays actual amperage 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. HBA for three phase is available. Contact RKC for details. The Century Series offers full PID Control, autotuning on demand, °C/°F, Reverse or Direct action, PV Bias, anti-reset windup and operator lock-out function. Twelve different field-configurable thermocouple types inputs, RTD, DC milliamp or voltage inputs as well as relay, voltage pulse, 4-20 mA and triac trigger outputs are available.
