Weidmuller Introduces New Modular Compact Terminal Blocks

Weidmuller USA, a leading provider of automation and industrial connectivity solutions, has recently announced the introduction of a new range of modular terminal blocks for distributed control system (DCS) signal marshaling. The new Klippon® Connect W2C and W2T terminal blocks offer flexibility in handling complex signal wiring in a very compact panel design.

W2C and W2T DCS Marshaling Terminal Blocks

Managing complex wiring in any process or manufacturing industry needs to offer flexibility for installing and maintaining automated systems.

Designed for complex circuit diagrams, the new Klippon Connect W2C and W2T terminal blocks come in four basic functions: continuity (the standard feed-through style), disconnect, fuse, and ground, all in a compact single or double-level arrangement for wiring flexibility.

When it comes to installation, the integration of PE contact on the DIN rail saves control cabinet space for both the single and double-level terminal blocks. Additionally, W2C and W2T terminal blocks come with multiple marking strip and marker tag options that make troubleshooting and maintenance simple.

Available as an accessory, the blocks allow the use of a potential-free shield bus offering a second alternative to PE connections for the single-level terminal blocks. For convenience in the distribution of analog and digital inputs and outputs, the terminal blocks are equipped with up to three cross-connection channels on all levels.

The new terminal blocks do have approval to be used in marine applications and harsh environments. For maximum operational safety and simplicity in planning, the terminal block design features clamping yoke connection technology. To further add unique connection security, the terminal blocks also feature Weidmuller's self-locking technology. With short-term function changes like the disconnection and additional fuse to terminal blocks, last-minute changes can be made in control cabinets without interfering with the existing wiring.

Another valuable benefit of the new terminal block ranges is the ability to connect multimeter leads in a wide number of locations throughout the block, including the screws themselves. This allows technicals to easily troubleshoot faults, regardless of installation method.

 

Additional Signal Marshaling Technologies

Beyond the new W2C and W2T DCS models, the company offers a range of signal marshaling technologies such as the Klippon Connect PRV and WMF terminal blocks. The PRV marshaling blocks come in a unique A-shaped design that not only reduces contact resistance but also saves up to 50% of cabinet space. In the switch cabinet, up to 1,700 signals per meter can be connected to the block through its secure push-in tension clamp.

The WMF (Weidmuller Multi-Functional) terminal block series comes with three cross-connection channels for a more flexible potential distribution. The terminal block's multi-functional signal marshaling solution makes it ideal for process control and power generation industries.

Klippon Connect: Industry Perspectives

According to Carlus Hicks, Director of the Cabinet Products Division for Weidmuller USA, the new signal marshaling solution handles a range of automation problems which includes late changes to the wiring without having to change the pre-existing setup. Adding to the potential of the new products, Carlus highlighted the concept of free shielding as a better alternative to conventional methods.

As the complexity of signal wiring and marshaling in modern industrial plants grows, engineers seek solutions that will not only offer flexibility in handling complex signal connections but also reliably save on installation space and time. Signal marshaling solutions like the new Weidmuller's Klippon Connect W2C and W2T ranges offer efficient, flexible, and reliable ways of managing complex signal wiring, making it a potential choice for engineers seeking modern signal marshaling solutions.
