4-20 mA HART Loop Protocol and Channel Isolation

The cable assembly incorporates dual-layer shielding to suppress electromagnetic interference across analog 4-20 mA HART loop channels and high-speed digital communications lines. Consequently, field transmitters pass raw sensor values through the heavy-gauge copper conductors without signal attenuation or phase distortion. While the outer sheath resists chemical exposure, the inner XLPE insulation maintains high channel-to-channel isolation, which prevents ground loops from corrupting critical control signals before they reach system terminal boards.

Frequently Asked Questions

Q: How do technicians maintain effective EMI/RFI noise suppression during cable routing?

A: Installers must ground the integrated tinned copper braid shield at a single point, usually at the system cabinet earth bar, because two-point grounding can create ground loop currents that induce noise into sensitive analog channels.

Q: Can engineers bend the KS1-20 cable sharply inside tight control cabinet ducting?

A: No, field crews must observe the minimum bending radius of approximately 55.2 mm (6 times the outer cable diameter). Exceeding this bend radius damages the internal aluminum foil shield, which degrades signal isolation performance.

Q: Does the KS1-20 cable support direct connection to Yokogawa MUB, MUD, and MRT series terminal boards?

A: Yes, the cable connectors mate directly with MUB, MUD, and MRT terminal assemblies, whereupon the locked connector shell prevents accidental physical disconnection caused by cabinet vibration.

Field Installation Guidelines

Lay the cable inside dedicated low-voltage instrument raceways, and separate it from high-power AC motor drives by at least 300 mm to avoid inductive cross-talk. When pulling the cable through cable trays, operators must maintain smooth, continuous tension without exceeding the maximum rated pulling force.

Inspect the pre-molded connectors at both ends for pin alignment before insertion. After seating the connector into the corresponding terminal board header, tighten the retaining screws securely. Finally, clamp the overall cable braid shield firmly to the control panel earth rail using a conductive grounding strap to complete the shield assembly ground.
