YOKOGAWA 16137-223 16137-222 Communication cable

The Yokogawa 16137-223 is a specialized communication cable, specifically an M-Bus B-Side Cable with a length of 2.5 meters. 

It is primarily utilized in legacy control environments where Yokogawa systems interface with Siemens APACS+ or QUADLOG architectures.

1. Introduction

The 16137-223 is an industrial-grade interface cable used to establish robust data links within a distributed control environment.

 While it carries a Yokogawa part reference in certain procurement databases, it is most frequently identified as the Siemens M-Bus B-Side Cable.

 Its purpose is to provide the physical connection for the "B" (redundant) side of an M-Bus communication network, ensuring that if the primary "A" side fails, the control system maintains continuous communication with I/O modules and processors.

2. Technical Parameter Table

These cables are often purchased in pairs or sets to satisfy the requirements of a redundant communication bus:

16137-151: The Side A equivalent (often in 4m or 2.5m lengths) for primary M-Bus communication.

16137-153: A 4-meter version of the B-Side cable for larger cabinet spans.

16137-225: I/O Bus B Cable (used for I/O rack-to-rack communication rather than the main M-Bus).

6EP Series: Siemens power supplies often found in the same APACS+ racks.

4. Product Advantages and Features

Redundancy Support: Specifically keyed for the "B" side of the M-Bus to ensure physical and logical separation from the primary bus.

Plug-and-Play Reliability: Pre-terminated with industrial connectors to eliminate wiring errors common with manual terminations in the field.

Noise Immunity: Heavy shielding protects critical control data from the electromagnetic interference common in motor control centers and power plants.

Durability: Designed for permanent installation in 19-inch racks with strain relief to prevent connection loss during vibration.

5. Application Cases

Control System Upgrades: Often used when a Yokogawa system (like CENTUM VP) is integrated with an existing Siemens APACS+ installation through a gateway.

Nuclear and Fossil Power Plants: Used in older safety-critical systems (QUADLOG) where high-availability bus communication is required by law.

Refinery Modernization: Connecting legacy I/O nests to updated controllers during "phased" system upgrades.

6. Other Models in the Same Series

The 16137 series includes various lengths and bus types to accommodate different rack distances:

16137-140 through 16137-230: A range of cables covering both M-Bus (Management Bus) and I/O Bus needs.

Side A vs. Side B: Most models in this series come in "A" and "B" variants to facilitate the dual-redundant architecture typical of APACS+ and ProSafe systems.
