ZC-DJYPVP 300/500V Shielded Flame-Retardant Computer Cable
ZC-DJYPVP carries process-control signals (4–20mA, HART, RS-485) through cable trays that share space with VFD outputs and high-current power feeders. The pair structure rejects common-mode noise; the per-pair and overall foil shielding blocks external EMI; the flame-retardant outer sheath meets IEC 60332-3 bunched-cable flame propagation.

Overview
Class 2 stranded copper twisted pairs, each pair individually shielded with aluminum-mylar foil + drain wire, overall shielding of aluminum-mylar foil + drain wire, ZR-classified flame-retardant PVC outer sheath. Standard pair counts 1, 2, 4, 7, 8, 10, 12, 16, 19, 24 — sized to actual signal count plus 10–20% spare.
Key Features
Individual + overall shielding
Cancels both differential and common-mode noise — keeps 4–20mA accuracy in trays shared with VFD outputs.
Flame-retardant outer sheath
ZR-class flame-retardant compound suitable for dense cable trays in process plants and data centers.
Applications
Process plant instrumentation
DCS, PLC, and field-instrument loops in refining, chemical, water treatment plants.
BMS analog and digital
Temperature, pressure, flow, valve-position signals between field devices and head-end controllers.
