process controllers tS COM ECO CONTROL & MEASUREMENT WWW.COMECOGROUP.COM Universal Programmable Controller RT1900-R ♦ DIN-rail or wall mounting ♦ 4-digit display ♦ Universal programmable input ♦ PID-fuzzy auto-tuning ♦ Up to 3 relay and 1 analog outputs ♦ RAMP/SOAK pattern control ♦ RS485 MODEBUS serial interface ♦ USB port for parameter storage RT1900-R is a microprocessor-based controller for DIN-rail mounting, with universal input accepting Pt100, 10 thermocouple types and various linear signals. It can have up to 3 relays (control or alarm) and analog output that may be controlled through ON/OFF and self-tuning PID-fuzzy algorithms as well as optional RAMP/SOAK pattern control. A bumpless auto-manual change-over is also built in the PID algorithm. RT1900-R is equipped with a 4-digit LED display and a 4-button keyboard for programming. A triple input/output/supply isolation protects the controller from electromagnetic disturbances. Communication features include RS485 MODEBUS interface and USB port for program parameter storage. RT1900-R is well equipped for trouble-free operation in harsh industrial conditions.
