WEIDMULLER 17234700000 Replacement for Klippon Connect Series

Product Overview

WEIDMULLER 17234700000 Replacement for Klippon Connect Series: Smooth Transition from Legacy PCB Terminal Blocks

The WEIDMULLER 17234700000 is a PCB terminal block connector from the Klippon Connect series, engineered for reliable signal and power distribution on printed circuit boards in industrial control panels, PLC racks, and DCS marshalling cabinets. As legacy control systems age and original components reach end-of-life or become difficult to source, engineers and procurement teams increasingly seek verified replacement units that preserve wiring layouts, PCB footprints, and system certification without triggering a full redesign cycle.

This listing provides a direct replacement or upgrade solution for the WEIDMULLER 17234700000, sourced from authorized supply channels and tested prior to shipment. Whether you are maintaining an existing Klippon Connect installation or migrating a legacy terminal block assembly to a current-generation equivalent, this unit is stocked and ready to ship from Xiamen with a 12-month warranty.

Seamless Upgrade Solutions

Replacing the WEIDMULLER 17234700000 is rarely an isolated task. In most industrial retrofit projects, the PCB terminal block sits within a broader control architecture that may also require attention during the same maintenance window. When upgrading Klippon Connect terminal assemblies, engineers commonly address adjacent components in the same pass to minimize future downtime.

On the signal side, WEIDMULLER WDU 2.5 and WDU 4 feed-through terminal blocks are frequently found in the same marshalling cabinet, providing the field-side wiring interface that connects to the PCB assembly. These are available as direct replacements and share the same DIN rail mounting standard. For power distribution within the same panel, WEIDMULLER W-Series power terminals and the ZDU 6 ground terminal blocks are common companions, ensuring that the protective earth and neutral conductors are properly terminated alongside the signal circuits.

In PLC-integrated installations, the PCB terminal block often interfaces with I/O modules from Siemens S7-300 or S7-1200 series, where the terminal block serves as the field-wiring breakout point between the I/O card and the field device. During a migration from S7-300 to S7-1500, the terminal block assembly is typically retained if the footprint is compatible, making the 17234700000 a cost-effective way to preserve the existing wiring infrastructure while upgrading the controller platform.

For DCS environments — particularly those running Honeywell Experion or ABB 800xA — the marshalling cabinet may contain WEIDMULLER SAK 2.5 or SAK 4 modular terminal blocks alongside PCB-mounted connectors. Replacing the 17234700000 in this context is straightforward, but technicians should also inspect the adjacent WEIDMULLER ZQV 4/3AN jumper links and WTR 4 test disconnect terminals, which are often due for replacement at the same service interval.

Where signal isolation is required between field devices and the control system, WEIDMULLER WAS 4/U signal conditioners or third-party DIN rail isolators may be installed in the same cabinet row. These do not require replacement during a terminal block swap but should be verified for continuity after re-termination. Similarly, WEIDMULLER ACT 20P analog signal converters installed in the same rack should be powered down and re-verified after any terminal block replacement to confirm signal integrity.

For projects involving communication-intensive upgrades — such as migrating from hardwired I/O to PROFIBUS DP or PROFINET — the WEIDMULLER IE-SW-BL05-5TX industrial Ethernet switch or equivalent PROFIBUS repeater modules may be installed in the same cabinet. While these are independent of the PCB terminal block, coordinating their replacement or firmware update during the same shutdown window reduces total project risk.

Retrofit Guidance FAQ

Q: Is the WEIDMULLER 17234700000 a direct drop-in replacement for the previous Klippon Connect generation?
A: Yes. The 17234700000 maintains the same PCB pitch and through-hole footprint as its predecessor in the Klippon Connect series. No PCB rework or re-drilling is required. Existing wiring can be re-terminated directly to the new connector without modification.

Q: What wiring tools are required for installation?
A: Standard screw-clamp termination requires a flat-blade screwdriver sized to the terminal’s torque specification (refer to WEIDMULLER datasheet for 17234700000). No special crimping tools are required for solid or fine-stranded conductors within the rated cross-section range. Ferrule crimping is recommended for fine-stranded wire to ensure long-term contact reliability.

Q: Does replacing this terminal block require any PLC program changes?
A: No. The 17234700000 is a passive terminal block with no active electronics or firmware. It does not appear in the PLC program, I/O configuration, or network topology. Program changes are not required, and the replacement does not affect PROFIBUS addresses, PROFINET device names, or any other communication parameters.

Q: Is this replacement compatible with existing DIN rail and cabinet space?
A: Yes. The Klippon Connect series uses standardized DIN rail mounting dimensions. The 17234700000 fits standard 35 mm DIN rail and occupies the same panel space as the unit it replaces. No cabinet modification or additional mounting hardware is required.

Q: What communication protocols are supported?
A: As a passive PCB terminal block, the 17234700000 is protocol-agnostic. It supports any signal type within its rated voltage and current range, including analog 4–20 mA loops, 24 VDC digital I/O, thermocouple signals, and RTD circuits. It is compatible with all major industrial communication architectures including PROFIBUS, PROFINET, Modbus RTU, and DeviceNet when used as the field-wiring termination point.

Q: Can this unit be used in SIL-rated safety applications?
A: WEIDMULLER Klippon Connect terminal blocks are used in safety-instrumented systems in many installations. Confirm the specific SIL rating and functional safety documentation for the 17234700000 with WEIDMULLER’s official datasheet before use in IEC 61508 or IEC 61511 applications.
