Selector Switch Station with Start / Stop Pushbuttons

Part number: PBS-3  |  Drawing D10044  |  Think-PLC Ready-Set-Go Series

A pre-wired, labelled and tested three-device motor control station built on Siemens SIRIUS ACT 3SU pilot devices in a Saginaw 3PBGX painted steel enclosure. A three-position maintained selector switch gives ON / OFF / AUTO mode selection, and two momentary black pushbuttons provide START and STOP commands.

All four normally-open contacts share a common 24 VDC feed and land on a single M12 8-pin A-coded male bulkhead with a 3.2 ft pigtail, so the station wires to a machine or a remote I/O drop with one cable. Legends are snap-in plates held in label holders, so the station can be re-legended in the field without changing hardware. Each unit ships with the customer drawing package it was built from: schematic, model view, cable diagram and bill of material.
