VT 1516-S-11

The VT 1516-S-11 card holder by Bosch Rexroth Indramat is part of the VT 3000 Analog Amplifiers series and provides a stable platform for the easy installation of a single amplifier card. It is equipped with an integrated power supply and supports a 10V differential amplifier input interface for seamless communication with microprocessors, programmable controllers, or computers. Designed primarily to control proportional valves with pilot valves, this holder ensures reliable card fixation and straightforward system integration.

Featuring four internal contact relays that switch all input signals through a built-in relay circuit and a change-over relay capable of polarity switching, the VT 1516-S-11 excels in versatility. It offers a pulse-width modulated output with a dithering effect to minimize hysteresis and ensure precise valve control. The holder provides a 20 mA minimum output bias current and two selectable ramp times of one and five seconds for tailored response characteristics. A built-in voltage stabilizer delivers a constant voltage supply, while four LEDs on the faceplate offer quick visual status indication of the input relays.

Terminals with the "ac" suffix feature pre-established internal connections and must not be repurposed. For accurate readings, measurements should be taken only with a high-impedance meter, and the amplifier should be positioned at least 1 meter away from radio transmitters or similar devices. Solenoid cabling must not run adjacent to the card to avoid interference. The VT 1516-S-11 can be shipped worldwide and is backed by a one-year warranty. Its robust construction, efficient signal handling, and comprehensive technical safeguards deliver dependable performance, making it ideal for demanding industrial automation and hydraulic control applications.
