Festo
8171508
Positioner CMSX-P-SE-C-U-F1-D-50-C
The Festo 8171508 is a digital, electropneumatic positioner featuring a double-acting design with a safety position that keeps pneumatic outlets closed. It operates within a pressure range of 0.3 MPa to 0.8 MPa (3 bar to 8 bar, 43.5 psi to 116 psi) using compressed air conforming to ISO 8573-1:2010 [7:4:4] and requires a 24 V DC nominal operating voltage with an analog signal range of 0–10 V, 0–20 mA, or 4–20 mA. Equipped with a backlit 7-segment LCD display, a linear potentiometer measuring principle, and a G1/8 pneumatic connection, it supports any mounting position using accessories.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
