Product Description:
Bosch Rexroth Indramat makes the VT 2000-48 E2. The VT 2000-48 E2's energy efficiency is a key factor in its functionality. That's because it uses less than 25 VA of power and draws less than 1 A of current. This low power consumption—about as low as you can get—helps keep control cabinets cool and industrial systems energy-efficient. By reducing heat production and the need for significant power sources and wiring, you avoid overheating and electrical risks. A safeguard against overcurrent situations is a 2.5 A T (time-delay) fuse built right into the amplifier. This fuse is designed to melt if the current exceeds a specific limit for a set amount of time. That's when it protects the amplifier and other system components from damage. A range of inputs and outputs on the VT 2000-48 E2 lets you accurately control hydraulic systems. One of the essential inputs is a voltage signal between 0 and +9 V that sets the intended position or flow rate of the proportional valve. That input converts the control signal directly into valve action and is linked to a standard potential—usually ground. The amplifier also has a differential input with 100 kΩ input resistance.
By cutting down on common-mode noise, that differential design ensures precise signal transmission. The amplifier can modify ramp time—from as little as 30 ms to 1 or 5 seconds (depending on the jumper setting)—to dynamically control the proportional valve. That means you can make either quick or gradual changes in valve position based on your application's needs. The VT 2000-48 E2's adaptability and integration into larger automation systems are improved by a number of auxiliary functions. One of those is the amplifier's controlled biasing current output, which can be adjusted from 10 mA to 300 mA. That helps the proportional valve overcome deadband and static friction. By fine-tuning the valve's initial response characteristics, you can get the performance you need.
The amplifier also produces a clock frequency output that can be set between 100 and 200 Hz for synchronization with other system components or pulse width modulation (PWM). You get precise control over the solenoid current output, which regulates the electromagnetic actuator of the valve. That output can be set to a maximum of 800 mA with a tolerance of ±10%. You also get voltage and current measurement sockets for monitoring and troubleshooting applications. These outputs, along with a regulated ±9 V voltage output to power additional sensors, make the amplifier a very accurate and versatile tool for hydraulic system management.
