Features:
- Spring-clamp service: field conductors retained without terminal-screw torque
- Three-wire rows: I/O, common, and +V distribution in one base
- Modular backplane: DIN-rail mounting with Flexbus continuation
1794-TB3S provides spring-clamp field termination beneath compatible FLEX I/O modules.
Its main service distinction is the conductor-retention method; electrical limits still come from the module and station design.
Acceptance should document module pairing, keying, wire preparation, retention results, V/COM loading, and base order.
Apter Power can coordinate official-document review, quotation, and sourcing support for 1794-TB3S.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Wire preparation: apply the documented conductor size and strip length.
- Insertion: seat the conductor fully with no exposed copper or loose strands.
- Retention: perform a controlled tug test after each serviced connection.
- Exact module: use the official installation instructions to approve the base.
- Keyswitch: preserve the module-specific position during replacement.
- Electrical limits: apply the required voltage, current, and isolation boundaries.
- De-energize: remove station power before opening the Flexbus connection.
- Sequence record: preserve the order of every downstream base and module.
- Final check: verify communication and field status across the restored station.
- Repeated panel service: use spring-clamp connections where approved module pairing permits.
- Three-wire sensors: distribute signal, common, and supply in a remote station.
- DIN-rail I/O: continue the FLEX I/O backplane through adjacent bases.
