The RB series is a performance temperature control series condensed into a slim 60mm depth case. Offered at an economical price, a new auto-tuning algorithm calculates optimum PID values to shorten the time to reach set value. After the PID values have been auto-tuned, Fine Tuning (FT) allows the operator to adjust control response speed with a 6-level adjustment parameter (-3 to +3) without changing the PID value. A start-up tuning function is used for applications which require a long time for conventional auto-tuning. This function can be selected at power-up, setpoint change, at power-up/setpoint change, and may be set as Only-once or Always-ON. These features mean stable control to eliminate overshoot/undershoot, and offers stability against external disturbances. The RB high performance controller provides precise control by sampling every 0.25 seconds.
It is offered as Heat only or Heat/Cool and comes equipped with the ability to store up to 4 set values, 2 digital inputs, up to 4 alarm outputs which include loop and heater break alarming as well as standard alarms, and a USB loader port for setting parameters. (Communication converter COM-K is necessary for USB connection.) Sizes include 1/16, 1/8 and 1/4 DIN in a NEMA4X/IP66 rated case.
Options include a retransmission output for a chart recorder or data acquisition and RS-485 communications to interface with a PC or PLC.
