Yokogawa KM55-020 Connector Terminal Block Cable for FA-M3 Systems
Product Introduction
The KM55-020 from Yokogawa is a dedicated accessory cable for the FA-M3 and FA-M3V programmable logic controller families. Specifically, this cable facilitates the electrical connection between a compatible I/O module and its associated connector terminal block. The 2.0-meter length offers extra reach in cabinet layout, allowing engineers to route wiring neatly across larger panel spaces.
Technical Specifications and Compatibility
First, it is crucial to understand the core function of this part. The KM55-020 serves as the physical bridge for signal transmission. The screw terminal assignments on the connector block directly match the pin assignments of the module connector, ensuring straightforward installation.
Specifically, the model code KM55-020 decodes to a 2.0-meter length. The KM55 series also offers other lengths, such as the -005 (0.5 m), -015 (1.5 m), and -030 (3.0 m), to accommodate different cabinet dimensions. However, there is a critical compatibility note for engineers. This cable cannot be used with certain 48-pin connector modules, including the F3YP04, F3YP08, F3YP14, F3YP18, F3YP22, F3YP24, F3YP28, F3NC32, and F3NC34.
Mechanical and Environmental Parameters
Moreover, this cable is built to withstand demanding industrial environments. The operating temperature range spans from 0 to 55°C, while storage conditions permit temperatures between -20°C and 75°C. Humidity tolerance is rated at 10 to 90% RH (non-condensing) for both operating and storage states.
Additionally, the surrounding atmosphere must be free from corrosive gases, flammable gases, or heavy dust. These specifications ensure that the KM55-020 maintains signal integrity and physical durability in standard factory automation settings.
Installation Guide
Next, proper installation is essential for reliable system performance. Before making any connections, always verify that the module and terminal block models are compatible with the KM55 series cable.
One key point to note is that the connector terminal block itself does not ship with this cable. Therefore, you must order the KM55-020 separately. During installation, confirm the pin assignment diagram for your specific module. The screw terminals on the block correspond directly to the module connector pins, which simplifies the wiring process. Route the 2.0-meter cable away from high-voltage power lines to minimize electromagnetic interference.
