The VT-VSPA1-1-1X-SO43A-1616 is a Bosch valve amplifier designed for proportional pressure valves. This device is compatible with all direct and pilot operated pressure valves without electrical position feedback, using a single solenoid as an actuating element. It facilitates differential input, which can be switched from voltage to current, as well as an additional command value input ranging from 0 to +9V. With functionally versatile clock frequencies of 100Hz and 160Hz, its ramp generator can be adjusted independently in both directions. This amplifier also offers reverse polarity protection. Its operating voltage is 24V DC, with an upper and lower limit of 35V and 22V DC, respectively. The unit consumes up to 50 VA power, with a current consumption of 1.8 Amps. It hosts a 32-pole male multi-point connector and measures 100 x 160mm. Its operating temperature ranges from 0 to 50°C, with a storage temperature between -25 to 85°C. The unit's front plate houses a "Ready for Operation" LED display. Before use, the DIL switches on the circuit board must be set according to the application. Training is needed to handle this device, and standard ESD precautions must be followed during its operation.
