Product Description

The VT 3000-3X-ES43A8-2590 is a VT 3000 series analog amplifier from Bosch Rexroth. It is especially designed for control of two types of proportional valves: pilot operated directional valves and direct operated pressure valves. The connection on the amplifier is a 32-pin terminal strip. This strip complies with DIN 41612. The VT 3000-3X-ES43A8-2590 comes in a Euro card format with 100 x 160 millimeter dimensions. The ambient temperature recommended by Bosch for the amplifier card is 0 to 50 degrees Celsius. The storage temperature recommended by Bosch is -25 to 85 degrees Celsius. As the card is open, it must be protected from dust, moisture and corrosive elements. Shipping weight of the VT 3000-3X-ES43A8-2590 is approximately 0.13 kilograms. The height of the card is 128.4 millimeters. The width of the front plate is 5.08 millimeters.

Nominal operating voltage for the VT 3000-3X-ES43A8-2590 amplifier is 24 Volts DC. The operating voltage range is 22 to 39 Volts DC. The power consumption under all operating conditions never exceeds 50 VA. The current consumption under all operating conditions never exceeds 1 Amp. The VT 3000-3X-ES43A8-2590 includes a protective fuse rated for 2.5 Amps.  To prevent damage, the VT 3000-3X-ES43A8-2590 must be plugged in or unplugged only when it is switched off. Bosch does not recommend use of plugs with LED displays or free wheel diodes for connecting the solenoids. Operators must only use measuring equipment with input impedance exceeding 100 kiloohms for making measurements on the amplifier card. The minimum distance between the VT 3000-3X-ES43A8-2590 and aerial lines and other radio frequency (RF) sources should be at least 1 meter. Operators must avoid laying solenoid or signal lines near power lines.
