RKC Instruments has announced the release of a high performance temperature control series condensed into a slim 60 mm 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 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 or setpoint change and may be set as OnlyOnce or AlwaysOn. These features mean stable control to eliminate overshoot/undershoot, and offer stability against external disturbances. The RB high performance controller provides precise control by sampling every 0,25 seconds.
It is equipped with the ability to store up to four set values, two digital inputs, up to four alarm outputs which include loop and heater break alarming as well as standard alarms, and a USB loader port for setting parameters. 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 RS485 communications to interface with a PC or PLC.
The RB series is for end users and the OEM market in industries such as semiconductor, chemical, food processing, plastics, packaging, and electronics.
