Product Description:
The VT-VSPA2-50-10/T1 is a valve amplifier manufactured by the reputable Bosch Rexroth Indramat for controlling direct operated proportional pressure valves. The servo amplifier has a power supply unit with making current limiter, this unit supplies all internally required positive and negative supply voltages. This servo amplifier is tested and certified to meet the highest quality standards before it is delivered. The amplifier is intended to be used as an integral component in industrial applications, it does not have any enclosure and should be protected from external interference. The installation, and handling of the VT-VSPA2-50-10/T1 valve amplifier should be handled by a well trained professional who is familiar with Bosch Rexroth products and have gone through the documentation delivered with the servo amplifier. The VT-VSPA2-50-10/T1 valve amplifier operates with a voltage of about 24 volts, the permissible lower limit range of input operating voltage for this valve amplifier is about 18 volts, while the upper limit is 35 volts. This valve amplifier also consumes a power of about 24 volts per ampere during operation, a current less than 2 amperes. A 2 ampere medium time-leg fuse is integrated into this amplifier, the fuse protects the amplifier and it is exchangeable in case of damage. The clock frequency of this valve amplifier is about 250 hertz. The analog inputs of this valve amplifier operates with a current input of about 4 to about 20 miliamperes, while the differential imputes for these analog inputs fall between 0 to about 10 volts. The VT-VSPA2-50-10/T1 is designed to be operated at an ambient temperature that falls between 0 to about 50 degrees Celsius, however during storage the amplifier can withstand a temperature as high as 85 degree Celsius. The total weight of this amplifier is about 0.15kilograms.
Frequently Asked Questions about VT-VSPA2-50-10/T1:
Q: Can the VT-VSPA2-50-10/T1 be unplugged during operation?
A: No. The VT-VSPA2-50-10/T1 amplfier card may only be plugged or unplugged when disconnected fron the power supply.
Q: Can plugs with LED lamps be used for solenoid connection with the VT-VSPA2-50-10/T1?
A: For solenoid connection, plugs fitted with free wheeling diodes or LED lamps must not be used.
Q: What type of instruments can me used to take measurement on the VT-VSPA2-50-10/T1?
A: Measurement on the VT-VSPA2-50-10/T1 amplifier may only be taken with instruments with resistance greater than 100 kiloOhms.
Q: Can unshielded cables be used for as command value cables with the VT-VSPA2-50-10/T1?
A: No. All electrical cables used as command value cables must always be shielded. Sheilds should be connected to 0v operating voltage on the card side and left open on the other end.
Q: What type of fuse should be used as backup fuses with the VT-VSPA2-50-10/T1 amplifier?
A: Backup fuses must have slow-blowing characteristics. This is due to the charging current of the smoothing capacitor on the card.
