Product Description

The VT 16000-2X-151-A is a Bosch Rexroth servo amplifier. It is designed for industrial applications. Specifically, the amplifier works with servo valves. The amplifier converts an input signal to a proportional output current for the torque motor, which controls the pressure balance in the pilot valve. In an unregulated power supply system, the VT 1600 voltage regulators must be used (option code “1”). The dual supply is connected to pins 14ac (+22 Volts, +28 Volts), pins 16ac (0 Volt), pins 20ac (–22 Volts, –28 Volts). The card provides regulated voltage at pins 12ac (+15), pins 22ac (–15 Volts). In a regulated ± 15 Volts power supply system, the VT 1600 voltage regulators must be removed (option code “0”). Otherwise, incorrect operation will result. The regulators are mounted on black heat sinks along the edge connector.

Note that installing a card without regulators into an unregulated system will damage the amplifier. Regulated power is connected to pins 14ac (+15 Volts), pins 16ac (0 Volts), pins 20ac (–15 Volts). The VT 16000-2X-151-A is available in Euro card format. You can install it in either a Euro magazine or a card holder. The front plate dimensions are 128 x 5 millimeters. The Euro card dimensions are 100 x 160 millimeters. The ambient temperature should not fall below 0 degrees Celsius or rise above 50 degrees Celsius. The amplifier can get damaged if it is connected while powered on. Electromagnetic interference can affect amplifier performance. Therefore radios and similar devices should be kept at least 1 meter apart from an installed amplifier. Only high impedance meters should be used for making measurements. Only qualified personnel should handle the VT 16000-2X-151-A amplifier.
