IA-DJYPVP 300/500V Intrinsic-Safety Shielded Instrument Cable
IA prefix on the model code designates the cable as suitable for intrinsic-safety loops in hazardous areas — refineries, LNG terminals, paint plants. Light-blue outer sheath visually distinguishes IS cable from standard process instrumentation so the two cannot be confused at termination.

Overview
Same conductor + pair construction as ZC-DJYPVP, but with: light-blue outer sheath (per IEC 60079 hazardous-area cable color convention), tighter geometric tolerances to limit pair-to-pair capacitance, individual + overall shielding to minimize cross-talk between IS and non-IS pairs. Suitable for Zone 0 / Zone 1 / Zone 2 explosion-risk areas per IEC 60079-14 wiring rules.
Key Features
Light-blue IS color
Visually unmistakable from standard instrument cable — eliminates IS/non-IS terminal mix-ups during commissioning.
Bounded capacitance and inductance
Geometric tolerances control L/C per IEC 60079-14 simple-apparatus wiring rules — IS-loop barrier calculations stay valid.
Applications
Petrochemical instrumentation
Refinery, LNG terminal, chemical plant IS loops where Zone 0/1 cable rules apply.
