Product Description:

The VT-UK2-3X/ES-E61-A083/U209 is a universal signal-conditioning card manufactured for the VT-UK2 Universal Cards series. Installed in 19-inch control racks, the board provides adjustable analog processing for hydraulic valves, position sensors, and motion controllers. By combining power-supply adaptation, amplification, and relay logic on a single Eurocard, it serves as an interface layer that simplifies wiring and stabilizes 0–10 V command loops in automated production equipment where proportional drives require precise reference voltages. This arrangement helps separate low-level control signals from rack-level supply distribution and gives the system a consistent analog stage for command handling and interlock functions.

Its electronics accept either 15 VDC or +24 VDC from the rack backplane, allowing the same PCB to fit low-power logic bays and higher auxiliary rails. A reference input of 10 V feeds the internal summing node, while signal conditioning is carried out by 6 operational amplifiers configured for gain, filtering, and polarity reversal. The conditioned path delivers a 10 V output that can supply 5 mA to downstream devices, which is suitable for proportional solenoid drivers and analog PLC channels. Stable amplifier operation and relay timing are maintained across the 0 °C to +50 °C ambient range, helping limit offset drift and keeping the processed command signal predictable during normal cabinet operation.

The card maintains Eurocard mechanics, standing 160 mm tall and 100 mm wide, and mates through a blade connector built to DIN 41 612. This connection brings power, analog signals, and relay contacts to the backplane in a single insertion step, which keeps the front edge free for adjustment access and status observation. When its analog stage sources the specified 5 mA at 10 V, heat rise stays within limits, provided the air temperature remains between 0 °C and +50 °C. Relay control is deterministic because pull-in occurs at +17 V and remains energized up to +28 V, so power-up and shutdown sequences stay consistent.
