SDC45V/46V Digital Indicating Controller with Multi-Input Computation Function
The DigitroniK SDC45V/46V is a highly advanced, high-precision compact digital indicating controller, featuring a 5-digit indicator, an input sampling cycle of 100 ms, indication accuracy of ±0.1%* of reading, and either 2 full multi-range analog inputs or 1 full multi-range input plus 2 DC current/voltage inputs. A dual-input computation function can be used for each input and output processing unit, allowing sensor input changeover, control based on the average of 2 PV values, control output changeover, feed-forward control, override control, etc. In addition, the input processing unit has a temperature-pressure correction function (2-input model: temperature correction or pressure correction).
*A representative figure. Indication accuracy differs depending on the input range type and temperature band.
- Dual-input computation capability and temperature-pressure correction are built in.
- The number of analog inputs, either two (full multi) or three (1 full multi and 2 DC current/voltage), can be selected (by model number).
- Control, ranging from cascade to backup control, is available for 1 or 2 loops.
- Sampling cycle of 100 ms and accuracy of ±0.1% rdg.
- Ample room for indication of vital information on dual 7-segment, 5-digit LED displays and an auxiliary 11-segment, 3-digit LED display
- Heat/cool control, using two control outputs
- Using the optional transmitter power supply function, a pressure transmitter can be directly connected.
- IP65 protection for the front panel
- Up to 16 recipe settings involving SP, event settings, etc., and 8 groups of fixed-value control output settings support automatic operation of equipment.
- Support for nonlinear processes using input/output broken line linear approximation tables
- Customizable parameter keys and LED
- A variety of inputs and outputs:
2 inputs, 7 outputs, 14 DIs, 8 DOs, 2 CT or AT inputs, RS-485 communications
