Product Description:

The VT-UK2-3X/ES-E61-A057/U527 is a plug-in universal analog processing card used in hydraulic and motion-control racks. It belongs to the VT-UK2 Universal Cards series and serves as a compact interface for rack-based analog control tasks. The board provides standardized conditioning and comparison functions for sensors, command signals, and servo-valve drives in modular industrial automation platforms. Its layout supports signal handling functions that are often required between field inputs and downstream control stages. It is intended for applications that rely on stable analog signal conditioning inside modular control assemblies.

The board follows the Eurocard 100 x 160 mm format, so it fits directly into 3U subracks without custom guides. A reference or summing node can be driven from a 10 V input, allowing the card to accept typical command voltages from PLC analog outputs. Internally, 6 operational amplifiers support differential amplification, summing, and filtering across separate functional blocks. This arrangement allows multiple analog processing tasks to be handled on one card rather than through external conditioning modules. The board also includes 5 null-point potentiometers for zero-shift correction on each amplifier channel to reduce static offsets in closed-loop circuits. At the front connector, the conditioned reference is available as a 10 V, 5 mA output signal for pilot cards or high-impedance measurement chains. Signal routing stays centralized on the card, which can simplify rack organization in dense control assemblies.

For powered operation, the card draws from either 15 VDC or +24 VDC, giving flexibility when only a single low-voltage rail is available. These supply options support installations that use either symmetrical control voltage or an auxiliary DC source. Ambient resilience is supported by a storage range of -20 to +70 °C, allowing spare boards to be stored on-site without climate control. The card uses common pinouts, identical board depth, and front-edge test points for consistent integration in modular racks. That combination helps the board fit established rack layouts where space and front-side access are limited.
