EBA-TEQ-706-A-10 by Vickers

The EBA-TEQ-706-A-10 electronic board is manufactured by Vickers as part of the Vickers Accessories series. Designed for hydraulic motion systems, the board acts as an interface between a machine controller and proportional or servo valves. It accepts dual LVDT feedback, provides reference voltages, and includes onboard switches that can activate or bypass command conditioning. By placing these functions on a single accessory, the module simplifies cabinet wiring and supports repeatable adjustment of valve position loops in industrial automation equipment.

Signal conditioning starts with a board-mounted command potentiometer that allows local trimming of the analog setpoint. A fixed attenuation of 1:10 further scales the external command. The card supports 2 drive channels that share a common supply. A jumper sets the input mode to Selectable (INT/EXT), allowing either the internal potentiometer or an external source. Each channel reads the main spool position through a 4-20 mA LVDT signal, and a second 4-20 mA pilot sensor can also be monitored. The board provides a stable ±10 V reference for external transmitters and measures 350.0 mm in length. Connector rows b, d, and z organize the field cabling, while drive-enable and ramp-enable switches support direct functional checks.

Power distribution across the rack is routed through 4 current link pairs that deliver the regulated supply to each channel without extra jumper wires. A supply test point exposes 24 V at the card edge so the bus voltage can be checked directly during operation. All plug-in terminals share a socket diameter of 2 mm, matching common laboratory leads and minimizing insertion force. The board layout combines signal access, power distribution, and measurement points in one card format for rack-based hydraulic control systems.
