Siemens Control box base AGM16.1

This is a plug-in terminal base intended for Siemens LOK burner control units, including LOK16. It provides 16 contacts and supports a rated voltage of 250 V and a rated current of 10 A. The housing is made of heat-resistant plastic and the cable entry uses an M16 thread. Electrical connection is made through terminal blocks; the base contains no active electronics. It is intended for gas, oil and dual-fuel burners and complies with European standards for burner equipment.

Control box bases of this type are selected by the exact control series and type designation, since pin layout and terminal assignment vary between models. Compare the part number with the existing control’s housing pattern and confirm that terminal markings match the wiring diagram. The base is a passive interface with no electronics. Verify the cable entry thread size, number of contacts, and plug configuration against the old base before ordering.

Failure of such a base usually shows as cracked housing, corroded terminals, or bent pins. The burner may then produce intermittent faults during the ignition sequence, lose signals, or fail to start. Inspect the base for visible damage, check that terminals are clean and tightly held, and ensure the control unit’s pins are straight.
