Features:
- Prefabricated Design for Error-Free Installation
- Optimized for PM891 RCU Control Links
- Environmentally Compliant with Global Trade Readiness
The ABB TK856 comes factory-terminated, eliminating the need for on-site soldering or crimping. This prefabricated construction reduces installation errors, speeds up cabinet assembly, and ensures consistent electrical performance across every unit.
Specifically engineered for use with the ABB PM891 controller, the ABB TK856 delivers dedicated RCU control link connectivity. Unlike general-purpose cables, it is verified for signal integrity under the electrical conditions found in AC 800M and 800xA systems, supporting deterministic control loop operation.
The ABB TK856 contains no SVHC substances under EU SCIP regulations and is outside WEEE scope, simplifying end-of-life management. Its HS Code 85444210 is internationally recognized, enabling fast customs clearance for global shipments.
The TK856 ABB Prefabricated RCU Control Link Cablet may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Deterministic Signal Transmission – The ABB TK856 ensures repeatable timing for RCU control links, which is critical for sequence-of-events recording and interlock logic in process automation.
- Passive Link – No Configuration Overhead – As a passive cable, the ABB TK856 introduces no latency, addressing, or firmware dependencies, making it transparent to system diagnostics.
- Physical Layer Integrity Check – System diagnostics on the PM891 can verify the presence of the ABB TK856 by monitoring control link status; an open circuit indicates cable disconnection.
- Compact Cabinet Integration – With a 7mm diameter and 0.09kg weight, the ABB TK856 supports high-density control cabinet layouts where space and weight are constrained.
- No SVHC Under EU SCIP – The ABB TK856 contains no Substances of Very High Concern, allowing its use in regulated industrial facilities and simplifying compliance reporting for system integrators.
- WEEE Exempt – The ABB TK856 falls outside the scope of the Waste Electrical and Electronic Equipment Directive, reducing end-of-life disposal obligations in EU member states.
- RoHS Status – No Declaration Needed – While not formally RoHS declared, the ABB TK856 meets typical industry expectations for restricted substance levels in automation cabling.
- Internationally Recognized HS Code – Classified under 85444210, the ABB TK856 is eligible for streamlined customs processing in most global markets, reducing supply chain delays.
- AC 800M Controller-to-RCU Connectivity – The ABB TK856 links the PM891 controller to remote control units in distributed control systems, supporting auxiliary I/O and status monitoring.
- 800xA System Cabinet Wiring – Used for internal cabinet wiring between controllers and termination units like the ABB TU860, reducing loose cabling and improving system organization.
- Control System Retrofit Projects – Ideal for replacing aged or damaged RCU link cables in existing ABB AC 800M or 800xA installations without modifying system architecture.
- Low-Voltage Control Signal Transmission – Suited for 30V DC control loops where shielded prefabricated cabling is required for noise immunity over short distances (≤1m).
