Serial Interface and Cable Configuration
The TK 821F uses a prefabricated two-channel cable assembly with integral connectors. It connects the FI 820F interface directly to the TB 870F terminal block. Therefore, the cable provides the physical serial interconnection without requiring field termination of individual conductors.
The specified cable length is 0.5 m. ABB also identifies the DFA 021 as an identical cable designation. Because the supplied documentation does not define conductor allocation, pin assignment, shielding construction, or electrical interface levels, those parameters should be verified against the associated FI 820F and TB 870F documentation before replacement or wiring work.
Frequently Asked Questions (FAQ)
Q: What equipment does the ABB TK 821F connect?
A: The cable connects an FI 820F interface to a TB 870F terminal block and supports two serial channels.
Q: Does the TK 821F require field-installed connectors?
A: No. The supplied description specifies integral connectors as part of the prefabricated cable assembly.
Q: Is the TK 821F RoHS compliant?
A: No. The supplied ABB data explicitly identifies the product as not RoHS compliant.
Field Installation Guidelines
Verify the cable designation, product ID, and connector configuration before installation.
Confirm that the receiving equipment is the specified FI 820F interface and TB 870F terminal block.
Isolate system power according to the applicable site maintenance procedure before making or removing connections.
Inspect both integral connectors for mechanical damage, contamination, or bent contacts.
Route the serial cable separately from high-current power conductors where practical to reduce electromagnetic interference.
Avoid sharp bends, excessive tensile loading, crushing, or repeated mechanical movement of the cable.
Do not modify the prefabricated connector assembly unless ABB documentation explicitly permits modification.
After installation, verify connector engagement and cable routing before restoring system power.
Check serial communication after installation and confirm that both intended channels operate correctly.
Use the applicable ABB wiring documentation to verify pin assignments and shielding or grounding requirements because those details are not specified in the supplied product data.
