Product Description
The model VT-VSPA1-1-11D-V0-0 is produced by Bosch Rexroth. This valve amplifier is designed for precise control of direct and pilot operated proportional pressure valves. This amplifier is optimized for systems without electrical position feedback and utilizes a single solenoid as its actuating component.
The VT-VSPA1-1-11D-V0-0 valve amplifier operates on a + 24 VDC power supply. This amplifier supports input ranges from 0 to + 9 V or 4 to 20 mA configurable for differential inputs. It features a maximum power consumption of 50 VA, safeguarded by a 2.5 A slow-blow fuse with current consumption capped at 1.8 A. The valve amplifier offers selectable ramp times from 30 ms to approximately 5 s adaptable for varying application demands. Output options include pilot currents with a maximum of 800 mA or 1600 mA adjustable using onboard controls and support clock frequencies of 100 or 160 Hz. The model integrates protections for cable breaks, reverse polarity and solenoid conductor short circuits. To ensure optimal performance and prevent any issues, use the model only with the accessories and attachments specified by the manufacturer.
The device connects via a 32-pole male multipoint connector and has a compact Euro card design measuring 100 x 160 mm. The model's operating temperature ranges from 0 to + 50 degrees C with storage tolerance from - 25 to + 85 degrees C. Additional features include cable break detection for current inputs, regulated voltage measuring sockets and a "Ready for Operation" signal indicator. This ensures system reliability in critical applications. The valve amplifier's robust design and protective features make it ideal for industrial automation and hydraulic systems needing efficient and precise pressure valve control.
