Series:
The VT-VSPD-1-2X/V0/0 belongs to the 2X series of digital amplifiers from REXROTH (Bosch Rexroth).
Features:
PC configuration: Valve selection, configuration and parameter setting can be done through the PC program BODAC.
Serial interface: Can be used for serial connection and local bus communication of up to 32 amplifiers.
Control value input: Support voltage or current control value input.
Programmable output: Supports programming of output stage frequency, leader, step, and final current or characteristic curve correction.
Ramp generator: A digital input can be used to invoke a preset given value parameter.
Error detection: Has error logic identification function, such as control value input cable interrupt detection.
Functions:
The VT-VSPD-1-2X/V0/0 is a digital amplifier for proportional valves without electronic stroke feedback. It receives the voltage or current signal from the controller, and after amplification and processing, outputs the corresponding current or voltage signal to control the spool position of the proportional valve, so as to achieve accurate control of flow, pressure and other parameters.
