Rated 24 V, with a maximum of 60 V across the cable assembly. It is designed for digital signal transmission — the unshielded construction and 0.14 mm² conductor suit 24 VDC I/O loops, not analog or high-speed fieldbuses.
Physical build and environment
Black PVC sheath, 11.5 mm outer diameter. The cores are coded-wire marked for identification.
