VT-MUXA2-2-1X/V0/1A

The VT-MUXA2-2-1X/V0/1A is a plug-in monitoring module produced by Bosch Rexroth Indramat for the VT-SWMA Modules series. It is designed for use in 24-volt control circuits that operate hydraulic or pneumatic solenoids in automated machinery. The device monitors electrical loads and interrupts the output when the current rises above the permitted level. This protective response helps prevent coil damage while supporting stable valve operation in process lines, material-handling equipment, and other electrically controlled systems.

The module operates from a nominal 24 VDC supply, allowing direct integration with common industrial control circuits without an additional voltage converter. Field conductors connect through screw terminals, which provide secure electrical contact in control cabinets exposed to normal machine vibration. The housing mounts on a DIN rail, allowing the unit to be positioned alongside relays, power supplies, and related control components. Its circuitry provides support for one or two connected solenoids and measures the load current in each active branch. The primary function is current monitoring and limiting, with the measured current compared against an adjustable reference during operation. If the permitted threshold is crossed, the internal switching stage responds automatically rather than allowing the excessive current to continue flowing through the coil.

When an overcurrent condition occurs, the module performs a rapid solenoid current shutoff to disconnect the affected load before excessive heat damages the winding. This action also helps isolate the fault from the remaining control circuit, reducing the likelihood that one overloaded branch will interfere with other connected equipment. The assembly weighs 0.28 kg, which keeps the added load on the DIN rail and enclosure structure low. Its circuit board, monitoring electronics, comparison stage, and switching output are contained in a single integrated module. The plug-in format provides accessible wiring and a compact arrangement for panels where available mounting space is limited. Its terminal-based connections also allow individual conductors to be inspected or secured without disturbing unrelated devices in the enclosure.
