RT1800 is a microprocessor-based controller with universal input, analog output, and up to 4 relays (control or alarm) that may be controlled through a number of algorithms such as ON/OFF, ON/OFF heating/cooling duplex, motor-valve control, PID, and self-tuning PID. A bumpless auto-manual change-over is built in the PID algorithm. A start-on timer allows one of output relays to be time-controlled. Two displays (for the measured value and for the set point) as well as an output-control bargraph ease operator duties. Carefully protected from electromagnetic disturbances by featuring both input and output optical isolation, RT1800 is well equipped for trouble-free operation in harsh industrial conditions
