Omega Engineering’s Platinum Series of microprocessor-based PID controllers is CE, UL and cUL compliant. The controllers feature bright 3-color (red, green, and amber), 9-segment LED display, high accuracy inputs and outputs, full autotune PID with fuzzy logic adaptive control, up to 99 chainable ramp soak programs with 16 ramps and soaks including ramp/soak events and built-in excitation firmware selectable at 5V, 10V, 12V and 24V. The series also has universal inputs for thermocouples, RTDs, thermistors, bidirectional and process voltage and process current. It comes with two or three programmable control/alarm/retransmission outputs: choice of DC pulse, solid-state relays, mechanical relays, analog voltage and current. All units come standard with USB communications; Ethernet and serial communications are offered as options. The controller is suited for laboratory, factory automation and chemical industries.
