The Nova PD550 is a digital temperature controller with two ramp and soak programs capable of storing 15 segments each for precision PID set point control. It is available in 1/16, 3/16, 1/8, and 1/4 DIN sizes. 

At the completion of a program, the controller can hold the set point, stop the outputs, or loop to one of the 30-segment programs. 

Its universal input accepts 23 input varieties, including thermocouple, RTD, and voltage inputs, and it can be easily configured for a 4-20 mA input. 

It is available with up to three (3) relays, two (2) 4-20 mA analog outputs, four (4) digital inputs, and an RS485 serial communication option which includes protocols for master/slave set point control, Modbus® ASCII and RTU, as well as PC software.
