Product Description:

The Bosch Rexroth Indramat VT 11118-11 belongs to the VT series as a versatile servo amplifier enhancing industrial automation system performance.

This amplifier utilizes a 24 VDC power source and operates from a voltage range of 21 V to 35 V to support standard industrial power variation. The VT 11118-11 device functions with minimal energy usage thanks to its 25–30 VA power consumption and 1.2 to 1.3 A current requirements. With 50 kΩ minimum input impedance, the servo amplifier requires 0 to ±10 V differential voltage input to respond promptly and precisely to control signals. This servo amplifier lets users customize output current within a range from 10% of its maximum (I10%) to the entire maximum current (Imax). The device also offers adjustable ramp times spanning 50 ms to 5 s. The controller device responds correctly to control signals by altering the solenoid voltage when the command polarity changes to ensure better performance control. This servo amplifier controls valve type 4WRA efficiently through 1.75 A of solenoid current that flows through a 5.4 Ω resistance.

The 12 screw terminals ensure strong and dependable links between all power supply, signal input, and output components. The VT 11118-11 measures 40 x 79 x 85.5mm with a 0.15kg weight, making it simple to install on top hat rail TH 35–7.5 for carrier rail mounting (EN 60715). The amplifier has basic solid object protection, which meets the IP20 standard of EN 60529 to withstand typical industrial settings. This product achieves dependable results within temperatures between 0 °C and 50 °C for operation while keeping it usable between -25 °C and +70 °C during storage. It can be purchased at Wake Industrial with a one-year warranty.
