We offer Super Digitronik Digital Indicating Controllers.The DigitroniK SDC45A46A is a highly advanced, high-precision compact digital indicating controller, featuring dual 5-digit indicators, an input sampling cycle of 25 ms, indication accuracy of 0.1 % of reading, and up to 2 control loops. It offers PID control using the latest "RationaLOOP" and "Just-FiTTER" algorithms. Up to seven control outputs (depending on the model) are available, selectable from relay contact, voltage pulse, triac (for position proportional output), current, continuous voltage, and transmitter power (24 Vdc).
