Festo
3929313
Positioner CMSX-P-S-C-U-F1-D-50-A
The Festo 3929313 is a digital, electropneumatic positioner featuring double-acting operation with a linear potentiometer sensing range of 0 degrees to 100 degrees and a 0.5 percent to 10 percent dead space size. This component operates on a 24 V DC nominal operating voltage with a 21.6 V to 26.4 V range, a maximum current consumption of 600 mA, and includes analog inputs supporting 0 to 10 V, 0 to 20 mA, and 4 to 20 mA signal ranges. It functions within an operating pressure of 0.3 MPa to 0.8 MPa utilizing compressed air as per ISO 8573-1:2010 [7:4:4] with a normal nominal flow rate of 50 l/min and features a 7-segment, backlit LCD display with key-based setting options.
