Allen-Bradley 1734-TB3 Terminal Base Screw Clamp

Allen-Bradley 1734-TB3 Terminal Base is a POINT I/O terminal base that provides 12 screw-clamp terminations for field wiring. As a 12-position IP20 screw-terminal base, it forms the wiring interface for a POINT I/O module when paired with the removable terminal block (RTB3). The 1734-TB3 is designed to work with the POINT I/O mounting base and terminal block assembly (1734-MB + 1734-RTB3) and accepts a 1734-RTB3 for terminal connections; the screw terminals are tightened to 0.6 Nm (7 lb-in) to ensure secure connections. This base is intended for DIN-rail mounted POINT I/O installations, enabling reliable, space-efficient wiring for up to 12 field signals. Typical applications include industrial automation and machine control where POINT I/O modules require robust, field-wiring interfaces for sensors and actuators. The base supports screw-clamp termination to distinguish it from the TB3S variant, which uses spring-clamp terminations. It is part of the POINT I/O ecosystem that includes TB-series bases and RTBs for modular I/O expansion.
