YOKOGAWA KS2-50*B Signal Cable

Configured for point-to-point analog and digital signal interconnectivity in CENTUM VP and CS 3000 systems, the YOKOGAWA KS2-50*B (KS2 Signal Cable) provides direct physical/electrical execution. The assembly routes field instrumentation signals between terminal units and DCS I/O modules through multi-pair twisted conductors.

Process Control & Signal Integrity Features

The 20-pair cable architecture features continuous foil shielding and drain wire configurations to optimize cross-talk suppression and limit high-frequency electromagnetic interference (EMI). The integrated copper conductors maintain low loop resistance and low capacitance, preserving signal amplitude and phase linearity across 4-20 mA HART loop protocol lines and high-speed digital I/O channels. Dual 40-pin molded connectors enforce strain relief and provide secure locking mechanisms at the DCS interface base.

Frequently Asked Questions

Q: How does the internal shielding prevent cross-talk between adjacent signal pairs?

A: Individual pair twisting combined with overall metallic shielding redirects induced ambient EMI and high-frequency noise straight to the protective earth connection before it affects adjacent wire pairs.

Q: Does the cable support online connector insertion and removal during active control operations?

A: Because the cable acts as a passive physical conductor with isolated pin channels, field technicians can mate or unmate the 40-pin connectors without interrupting system logic power.

Q: Can the cable carry HART digital communication signals concurrently with 4-20 mA analog signals?

A: Yes, the conductor geometry and low capacitance profile pass frequency-shift keying (FSK) HART signals overlaid on standard 4-20 mA DC analog current loops without signal distortion.

Field Installation Guidelines

Inspect the 40-pin connectors at both cable ends for bent pins or debris before engagement. Align the connector keyways with the receptacle on the I/O module or terminal board, then seat the connector firmly until the retention latches lock into position. Maintain a minimum bend radius equal to ten times the outer cable diameter during routing to prevent internal conductor strain.

Route the signal cable through grounded metallic cable trays, keeping it isolated from AC power distribution lines by at least 300 mm. Ensure the overall cable shield drain wire terminates to the system ground bar at one end only to eliminate circulating ground loop currents.
