Yokogawa PLC FA-M3 Temperature Control and PID Module F3CU04-1S
Specifications
General - The F3CU04-0S, occupying a single slot, controls up to four loops. - The F3CU04-1S, occupying two slots, controls up to four loops. - PID constants, set points and some other control parameters are stored in the module, eliminating the need to set up parameters before each operation. A specific SP backup procedure needs to be executed to store set points to the EEPROM. Otherwise, set points are not stored to the EEPROM when updated. Input - Individual input channels are isolated from each other, as well as from the internal circuit. Control - Auto-tuning and the “super” feature that makes use of fuzzy logic to suppress output overshooting are provided as standard functions to achieve optimal control. - Heating and cooling control are also supported. Using a cooling output, however, may require reduced number of output loops, or use of another output module. (The F3CU04-1S allows both a heating output and cooling output without reduction in the number of output loops.) - The module offers cascade control and other compound loop controls. Output - The control output type is time-proportional PID. Depending on the wiring, the module can be connected to a relay or an SSR. - The F3CU04-1S also provides continuous PID output (4-20 mA).
