Digital Temperature Controller D series REX-D100 REX-D400 REX-D900 General Description The D series controller features wide variety of functions, such as fuzzy logic algorithm, universal input/output, retransmission and digital communication. The D series controller eliminates bothersome modifications, and is ideal for applications to which simple standard controller does not fit. The REX-D900Z for control motor is also available. Feedback resistance is not necessary so that you can save wiring cost and do not have to worry about feedback resistance failure. Features Fuzzy logic algorithm Standard universal inputs and outputs Ramp rate setting of setpoint change Input type can be selected from twelve different Standard universal inputs and outputs thermocouples, two RTDs or eight different DC current inputs, and be easily changed through the front keys. The D series Retransmission also offers a choice of three different standard outputs, relay, Two setpoints voltage pulse for SSR drive or 4-20mA DC. The D series eliminates bothersome plug-in modules or modification with soldering. Retransmission (Analog output) Fuzzy logic algorithm The D series provides a retransmission output. Output types can be chosen among the measured value, set value, The D series controller features an advanced fuzzy logic algorithm that suppresses and eliminates overshoot and deviation, manipulated output, or current transformer input. Output signal can be selected from 0-5V, 0-10V, 1-5V, 0-20mA undershoot on startup and SV change. or 4-20mA. Fuzzy "OFF" Two setpoints Fuzzy "ON" Fuzzy "ON" You can have two independent setpoints values, and switch it Fuzzy "OFF" from each other by contact input. Various optional functions Various optional functions are available. Ramp rate setting of setpoint change Three phase or single phase heater break alarm Loop break alarm You can limit the ramp rate of setpoint change by setting the NEMA4X waterproof/dustproof protection for REX-D100 maximum tolerable amount of SV change per minute. This RS-422A/RS-485 digital communications function makes the D series suitable for applications which do not allow radical output amount change.
