VT-SWMA-1-11/V0/0

The VT-SWMA-1-11/V0/0 is an auxiliary switching and monitoring module manufactured by Bosch Rexroth Indramat and supplied under the VT-SWMA Modules series. Installed inside a control cabinet, the unit distributes 24 V power and relays discrete status lines to programmable logic controllers, creating a direct interface between field sensors and central automation hardware. It fits onto standard DIN rails and consumes minimal panel depth. The slim board profile allows multiple modules to be installed side by side without requiring enclosure modifications.

Primary power is accepted at a nominal 24 VDC, yet the circuitry remains active when the rail dips to 18 V and tolerates surges up to 35 V. This wide operating window protects against brownouts caused by cable losses or battery float conditions. With all channels energized, the board draws no more than 0.5 A, resulting in a peak power demand of 12 VA that must be considered when sizing cabinet supplies and thermal management systems. Operation within this range keeps the regulators out of dropout and preserves stable switching thresholds as temperatures change. Inrush current is negligible, so a 1 A slow-blow fuse can provide protection during startup and fault conditions.

Field conductors terminate on 12 screw terminals, providing vibration-resistant connections without requiring special crimp tools. The plastic enclosure carries an IP20 rating, so live parts are protected against finger contact when the module is mounted on a DIN rail inside a closed panel. Components operate across the available input range without auxiliary regulators, simplifying installation in systems that already provide 24 V rails. All control electronics operate at a DC control level, enabling direct pairing with relays, optoisolators, and low-power solenoid drivers used throughout industrial machinery. Clear terminal markings help users identify connections during routine maintenance without disturbing adjacent wiring.
