Yokogawa KS1-02 Signal Cable – 40-Pin to 40-Pin I/O Connection Cable for CENTUM VP and ProSafe-RS

Application Scenarios

In a CENTUM VP DCS installation, engineers are commissioning a new FIO analog input module. The field wiring has been terminated at the marshalling cabinet, but the connection between the I/O module in the FCS rack and the terminal board remains incomplete. Without the proper interface cable, the module cannot receive signals from field transmitters, and the control loops remain non-functional.

The Yokogawa KS1-02 solves this with a factory-terminated 40-pin connector on each end. Engineers simply plug one connector into the I/O module faceplate and the other into the corresponding terminal board port. The 2-meter length accommodates the typical spacing between adjacent cabinets in a control room lineup, while the shielded construction prevents electromagnetic interference from nearby power cables and variable frequency drives from corrupting analog signals. The pre-terminated design eliminates the need for field crimping and continuity testing, reducing commissioning time per channel from several minutes to seconds.

In ProSafe-RS safety instrumented system applications, the KS1-02 provides the same reliable interconnection for safety I/O modules, where signal integrity directly affects safety function performance . For installations requiring CSA non-incendive certification, the KS1-02*B/NL variant supports hazardous area applications .
