VT3002-2X/64G

The VT3002-2X/64G analog amplifier board is manufactured by Bosch Rexroth Indramat for the VT 3000 Analog Amplifiers series. The board serves as a plug-in interface that receives low-level reference signals and conditions them for proportional valves and other electrohydraulic loads in industrial automation lines. Its plug-in layout provides convenient access within machine control racks when signal channels require calibration.

The board occupies a single Euro-format footprint, so it slides into 100 mm × 160 mm card cages commonly used in modular control chassis. Signal and power lines reach the printed circuit board through a backplane connector that follows the DIN 41612 profile, allowing standardized mating with compatible rack headers. Traces and copper planes support a continuous load of 3 A, accommodating the current drawn by typical proportional solenoids without excessive temperature rise. For panel integration on hat rails, the carrier accepts a vertical orientation only, which keeps ventilation paths clear and prevents lateral stress on the solder joints. Internally, the amplifier channels use a 64-pole backplane assignment that provides separate pins for differential inputs, reference voltages, and diagnostic outputs.

Wiring to discrete field devices is completed through front-mounted plug-in screw terminals rated for conductors up to 4 mm², providing a secure clamp for multistrand machine cabling. A lever-actuated latch locks the terminal block to the faceplate, enabling tool-free removal during service while preserving the coding for the connector form used by this model. The module supports screw or hat-rail mounting, allowing either attachment method to suit the enclosure hardware. All terminal rows are rated for a maximum of 48 VAC/DC, allowing low-voltage logic and sensor circuits to share the module without exceeding the terminal voltage limit. The front-access wiring arrangement also keeps field connections separate from the backplane interface, reducing interference with adjacent cards during routine adjustments.
