Static screened data transmission cable for control technology
RD-Y(ST)Y: PVC Process control data cable for, e.g., control stations/ units and monitoring systems, Maxi TERMI-POINT®, Paired stranding, Static screen foil
- Decoupling of circuits by means of twisted-pair (TP) design (crosstalk effects)
- RD-Y(ST)Y is used as a data transmission cable for applications such as monitoring systems and control units
- Measurement, control and regulation technology and also in control rooms of power plants and industrial facilities.
- Suitable for transmission of analog and digital signals up to a frequency of about 10 kHz
- Designed for fixed installations in enclosed rooms.
- Outer sheath colour: grey or
blue for intrinsically safe systems
- Variant with 2 double cores twisted as star quad
- Flame retardant acc. to IEC 60332-1-2
Norm references / Approvals
- Based on DIN VDE 0815
