Installation

INSTALLATION WORKFLOW
Selection, wiring and verification
Confirm the exact system configuration before installation.
1 · Identify the station
Confirm the installed system uses the SIMATIC SC TB16SC mechanical and electrical format.
2 · Plan the module set
Count the required single-width analog and digital SC modules; the official limit is eight slots.
3 · Calculate loading
Verify the total 1L+/2L+ current and the 1.5 A maximum per parallel-fed slot.
4 · Prepare spring terminals
Use conductor preparation and wiring practices specified for the installed SIMATIC SC station.
5 · Inspect the assembly
Check terminal retention, polarity, module seating and supply distribution before energizing.

Compatibility

SELECTION CHECK
Compatibility and model identity
The complete part number and system requirements must match.
Module family
Designed for compatible analog and digital SIMATIC SC electronic modules.
Slot format
Accepts up to eight single-width module positions.
Electrical loading
The connected module set must remain within the 8 A total and 1.5 A-per-slot limits.
Terminal variant
This 0BH01 model uses spring terminals; screw-terminal TB16SC variants are not identical replacements.

FAQ

BUYER AND ENGINEER CHECKLIST
Six model-specific questions
Checks for product identity, condition, supplier evidence and technical fit.
Q1 · How is the exact terminal block verified?
Match 6ES7120-0BH01-0AA0 and the TB16SC spring-terminal description on the label, photos and quotation. Do not accept only the shortened TB16SC name.
Q2 · How can New, Used or Refurbished condition be distinguished?
Inspect current photos of every spring terminal, the module slots, supply markings and enclosure. Bent contacts, conductor residue, tool marks or repaired latches should be disclosed.
Q3 · How should a supplier be qualified?
Verify its legal identity, payment beneficiary and traceable transaction process, then require the official Siemens one-page data sheet tied to the complete part number.
Q4 · What must engineering check before ordering?
Confirm the SIMATIC SC platform, spring-terminal requirement, eight-slot capacity, 8 A total limit, 1.5 A-per-slot limit and mechanical dimensions.
Q5 · What evidence should be requested before payment?
Request dated front, rear and terminal close-ups showing the complete code, supply rails, all slot positions and packaging condition.
Q6 · Can a similar TB16SC suffix be substituted?
Not automatically. Spring and screw terminal versions differ, and supply distribution, slot arrangement and mechanical fit must be checked against the installed station.
