Product Details：
Product Dimensions：
The Beckhoff ZB3100 is a bus end terminal designed for use with the Beckhoff Bus Terminal system (KLxxxx). Its primary function is to terminate the K-Bus within a Bus Terminal block, ensuring correct data transmission and signal integrity.
Product Designation: Bus end terminal
Part Number: ZB3100
System Compatibility: Beckhoff Bus Terminal system (KLxxxx series)
Function: K-Bus termination
Terminal Points: 2 connection points (for K-Bus power supply connection)
Connection Technology: Cage clamp technology (tool-free connection for solid wires, or fine-stranded wires with a ferrule)
Connection Cross-section (Single-wire): $0.08 \text{ mm}^2$ to $1.5 \text{ mm}^2$ (28 AWG to 16 AWG)
Connection Cross-section (Fine-wire with ferrule): $0.25 \text{ mm}^2$ to $1.5 \text{ mm}^2$ (24 AWG to 16 AWG)
Operating Temperature: $0 \text{ °C}$ to $55 \text{ °C}$ (32 $\text{ °F}$ to 131 $\text{ °F}$)
Installation: Snaps onto the standard 35 mm DIN rail.
Essential System Component: It is mandatory for proper operation of a Bus Terminal block, ensuring the K-Bus signal integrity at the end of the segment.
Easy Installation: Like all Beckhoff Bus Terminals, the ZB3100 snaps easily onto the DIN rail and is designed for quick assembly.
Reliable Connection: Utilizes robust cage clamp connection technology, which provides reliable, vibration-resistant, and maintenance-free wiring.
Compact Design: Features the standard terminal housing design, maintaining a small footprint within the control cabinet.
Mandatory Use: The ZB3100 is absolutely necessary to properly close a Bus Terminal block. Without it, the K-Bus will not function correctly, leading to communication errors or system failure.
Installation Location: It must be the last element in the Bus Terminal block assembly, placed directly after the final I/O terminal.
Power Connection: While it terminates the K-Bus, the two integrated terminal points can be optionally used to feed the K-Bus power supply (e.g., $24 \text{ V}_{\text{DC}}$) through the block, but this is typically done via the Bus Coupler or a Power Feed Terminal. Refer to the specific system documentation.
Compatibility: Ensure it is used exclusively with the Beckhoff KLxxxx series of Bus Terminals. It is generally not used with the newer EtherCAT Terminal system (ELxxxx), which has different termination requirements.
Wiring Practice: Follow standard industrial wiring practices, ensuring proper stripping length and use of ferrules for stranded wires to ensure the best cage clamp connection.
The ZB3100 Bus End Terminal is used in any industrial automation and control system that utilizes the Beckhoff Bus Terminal system (KLxxxx).
Its application is systemic rather than functional, as it is required in any location where an I/O station is built using these terminals.
Typical applications include:
Machine Control: Essential in I/O stations for controlling machinery across various industries (e.g., packaging, printing, assembly).
Building Automation: Used in distributed control systems for HVAC, lighting, and security monitoring.
Process Instrumentation: Employed in small to medium-scale process control applications where the robust and modular nature of the Bus Terminals is beneficial.
Distributed I/O: Any configuration where a Bus Coupler (e.g., BKxxxx) is used to connect a series of I/O Terminals to a fieldbus network (like PROFIBUS, CANopen, or EtherCAT via a dedicated Bus Coupler) requires the ZB3100 at the end of the terminal segment.
